Merge #10821: Add SSE4 optimized SHA256
6b8d872 Protect SSE4 code behind a compile-time flag (Pieter Wuille)
fa9be90 Add selftest for SHA256 transform (Pieter Wuille)
c1ccb15 Add SSE4 based SHA256 (Pieter Wuille)
2991c91 Add SHA256 dispatcher (Pieter Wuille)
4d50f38 Support multi-block SHA256 transforms (Pieter Wuille)

Pull request description:

  This adds an SSE4 assembly version of the SHA256 transform by Intel, and uses it at run time if SSE4 instructions are available, and use a fallback C++ implementation otherwise. Nearly every x86_64 CPU supports SSE4. The feature is only enabled when compiled with `--enable-experimental-asm`.

  In order to avoid build dependencies and other complications, the original Intel YASM code was translated to GCC extended asm syntax.

  This gives around a 50% speedup on the SHA256 benchmark for me.

  It is based on an earlier patch by @laanwj, though only includes a single assembly version (for now), and removes the YASM dependency.

2f21e55514 Remove legacy InstantSend code (#3020)
* Remove ppszTypeName from protocol.cpp and reimplement GetCommand

This removes the need to carefully maintain ppszTypeName, which required
correct order and also did not allow to permanently remove old message
types.

To get the command name for an INV type, GetCommandInternal uses a switch
which needs to be maintained from now on.

The way this is implemented also resembles the way it is implemented in
Bitcoin today, but it's not identical. The original PR that introduced the
switch case in Bitcoin was part of the Segwit changes and thus never got
backported. I decided to implement it in a slightly different way that
avoids throwing exceptions when an unknown INV type is encountered.

IsKnownType will now also leverage GetCommandInternal() to figure out if
the INV type is known locally. This has the side effect of old/legacy
message types to return false from now on. We will depend on this side
effect in later commits when we remove legacy InstantSend code.

* Stop handling/relaying legacy IX messages

When we receive an IX message, we simply treat it as a regular TX and relay
it as such.

We'll however still request IX messages when they are announced to us. We
can't simply revert to requesting TX messages in this case as it might
result in the other peer not answering due to the TX not being in mapRelay
yet. We should at some point in the future completely drop handling of IX
messages instead.

* Remove IsNewInstantSendEnabled() and only use IsInstantSendEnabled()

* Remove legacy InstantSend from GUI

* Remove InstantSend from Bitcoin/Dash URIs

* Remove legacy InstantSend from RPC commands

* Remove legacy InstantSend from wallet

* Remove legacy instantsend.h include

* Remove legacy InstantSend from validation code

* Completely remove remaining legacy InstantSend code

* Remove now unused spork

* Fix InstantSend related test failures

* Remove now obsolete auto IS tests

* Make spork2 and spork3 disabled by default

This should have no influence on mainnet as these sporks are actually set
there. This will however affect regtest, which shouldn't have LLMQ based
InstantSend enabled by default.

* Remove instantsend tests from dip3-deterministicmns.py

These were only testing legacy InstantSend

* Fix .QCheckBox#checkUsePrivateSend styling a bit

* s/TXLEGACYLOCKREQUEST/LEGACYTXLOCKREQUEST/

* Revert "verified via InstantSend" back to "verified via LLMQ based InstantSend"

* Use cmd == nullptr instead of !cmd

* Remove last parameter from AvailableCoins call

This was for fUseInstantSend which is not present anymore since rebase

780bffeb78 Enable stacktrace support in gitian builds (#3006)
* Remove use of -rdynamic

This causes check-symbols to fail horribly and also turned out to be not
required when using libbacktrace. It was only required when using
"backtrace()" from "<execinfo.h>"

* Remove spurious ], from configure.ac

* Add -DENABLE_STACKTRACES=1 to CMakeLists.txt

* Remove unused method my_backtrace_simple_callback

* Use fs::path().filename() instead of basename()

* Add static g_exeFileName and g_exeFileBaseName

* Use .exe.dbg file when available

* Use uint64_t instead of uintptr_t

* Implement GetBaseAddress() for unix and win32

* Implement unified crash_info and use it everywhere before printing crash info

* Print a serialized version of crash_info when there is no debug info

* Implement "-printcrashinfo" command line option

* Compile stacktrace support unconditionally and only make crash hooks conditional

This also renames the --enable-stacktraces option to --enable-crash-hooks

* Enable crash hooks in win/linux Gitian builds

* Try to load .debug file on MacOS and enable crash hooks for osx Gitian builds

* Check for dsymutil and if it needs --flat

* Create .debug files in osx Gitian build

* Handle review comments

* Also print crash description when no stacktrace is available

* Unconditionally add -g1 debug information

Instead of making it dependent on "--enable-crash-hooks". We will need the
debug info every time now, even in release builds.

* Put MacOS debug info into dSYM symbols instead of plain .debug files

* Implement MacOS specific GetBaseAddress

Implement MNAUTH and allow unlimited inbound MN connections (#2790)
* Sort evo/* source files in Makefile.am

* Keep track of proRegTxHash in CConnman::masternodeQuorumNodes map

We will later need the proRegTxHash

* Fix serialization of std::tuple with const rvalue elements

Having serialization and deserialization in the same specialized template
results in compilation failures due to the "if(for_read)" branch.

* Implement MNAUTH message

This allows masternodes to authenticate themself.

* Protect fresh incoming connections for a second from eviction

Give fresh connections some time to do the VERSION/VERACK handshake and
an optional MNAUTH when it's a masternode. When an MNAUTH happened, the
incoming connection is then forever protected against eviction.

If a timeout of 1 second occurs or the first message after VERACK is not
MNAUTH, the node is not protected anymore and becomes eligable for
eviction.

* Avoid connecting to masternodes if an incoming connection is from the same one

Now that incoming connections from MNs authenticate them self, we can avoid
connecting to the same MNs through intra-quorum connections.

* Apply review suggestions

48d92f116e Implement optional pretty printed stacktraces (#2420)
* Add libbacktrace to depends

This is currently only useful to extract symbols. It fails to gather
stacktraces when compiled with MinGW, so we can only use it to get symbol
information from a stack trace which we gathered outside of libbacktrace.

* Add -mbig-obj to CXXFLAGS for MinGW builds

* Implement stacktraces for C++ exceptions

This is a hack and should only be used for debugging. It works by wrapping
the C++ ABI __wrap___cxa_allocate_exception. The wrapper records a backtrace
and stores it in a global map. Later the stacktrace can be retrieved with
GetExceptionStacktraceStr.

This commit also adds handlers to pretty print uncaught exceptions and
signals.

* Use GetPrettyExceptionStr for all unhandled exceptions

* Use --enable-stacktraces in CI for linux32/linux64

* Register exception translators to pretty print exceptions in unit tests

* Catch and print python exceptions when stopping nodes

Otherwise the code at the bottom is never executed when nodes crash,
leading to no output of debug.log files on Travis.

* Remove now unneeded/unused TestCrash methods

* Remove CActiveLegacyMasternodeManager

* Remove sentinelping RPC

* Remove unused P2P messages and inv types

There are still places where these are used in the code. The next commits
will clean these up.

* Remove MNB/MNP/MNVERIFY related code from masternode(man).h/cpp

* Remove all legacy code regarding block MN payee voting

* Remove MASTERNODE_SYNC_LIST and MASTERNODE_SYNC_MNW states

Also replace all uses of IsMasternodeListSynced and IsWinnersListSynced
with IsBlockchainSynced.

* Remove unsupported masternode RPCs

* Remove UpdateLastPaid methods

* Remove duplicate deterministicmns.h include

* Remove masternode.conf support

* Remove legacy MN lists support from masternode list GUI

* Remove unnecessary AskForMN call

* Remove compatibility code in CPrivateSendQueue::GetSignatureHash

* Don't add locally calculated MN payee in case GetBlockTxOuts failed

This is not valid in DIP3 mode

* Remove check for IsDeterministicMNsSporkActive in "masternode status"

* Move CMasternode::IsValidNetAddr to CActiveDeterministicMasternodeManager

* Remove use of CMasternode::CheckCollateral in governance code

* Remove uses of MASTERNODE_SENTINEL_PING_MAX_SECONDS/MASTERNODE_SENTINEL_PING_MAX_SECONDS

* Remove support for "-masternodeprivkey"

* Remove pre-DIP3 vote cleanup

* Remove compatibility code for quorumModifierHash/masternodeProTxHash

* Remove check for invalid nBlockHeight in CMasternodePayments::GetBlockTxOuts

...and let it crash instead. We expect this method to be called with the
correct height now (after DIP3 was fully deployed).

* Remove ECDSA based Sign/CheckSignature from CGovernanceObject

Only masternodes sign governance objects, so there is no need for ECDSA
support here anymore.

* Always add superblock and MN reward payments into new block

* Always check block payees (except if fLiteMode==true)

* Always allow superblock and MN payees in same block

* Remove/Fix a few references to masternode.conf and related stuff

Also delete guide-startmany.md and masternode_conf.md

* Implement NotifyMasternodeListChanged signal and call governance maintenance

* Remove non-DIP3 code path from CMasternodeMan::Find

* Remove remaining unused code from CMasternode/CMasternodeMan

* Always load governance.dat on startup

* Mine an empty block instead of incrementing nHeight from chain tip in miner tests

This test is crashing otherwise in GetBlockTxOuts as it tries to access a
previous block that is not existing.

* Skip MN payments verification on historical blocks (pre-DIP3 blocks)

Even though DIP3 was active on BIP9 level, the spork was not active yet at
that point meaning that payments were not enforced at that time.

* Remove unused state and CollateralStatus enums

* Unconditionally return false from IsBlockPayeeValid when IsTransactionValid returns false

IsTransactionValid already handles the case where IsDIP3Active() returns
false, making it return true.

* Add override keyword to CDSNotificationInterface::NotifyMasternodeListChanged

* Fix help for masternodelist status (POSE_BANNED and no OUTPOINT_SPENT)

Implement CDummyDKG and CDummyCommitment until we have the real DKG merged (#2492)
* Add SPORK_17_QUORUM_DKG_ENABLED spork

* Implement CDummyDKG and CDummyCommitment until we have the real DKG merged

This is only used on testnet/devnet/regtest and will NEVER be used on
mainnet. It is NOT SECURE AT ALL!

See comment in quorums_dummydkg.h for more details.

* Test simple PoSe in DIP3 tests

* Generate 2 instead of 4 blocks per iteration in PoSe tests

4 was based on old chainparams where I used larger phases.

* Only sleep when necessary in PoSe tests

* Fix typo in comment

* Give PoSe tests more time and sync after fast-forward

Implement and enforce DIP6 commitments (#2477)
* Add LLMQ parameters to consensus params

* Add DIP6 quorum commitment special TX

* Implement CQuorumBlockProcessor which validates and handles commitments

* Add quorum commitments to new blocks

* Propagate QFCOMMITMENT messages to all nodes

* Allow special transactions in blocks which have no inputs/outputs

But only for TRANSACTION_QUORUM_COMMITMENT for now.

* Add quorum commitments to self-crafted blocks in DIP3 tests

* Add simple fork logic for current testnet

This should avoid a fork on the current testnet. It only applies to the
current chain which activated DIP3 at height 264000 and block
00000048e6e71d4bd90e7c456dcb94683ae832fcad13e1760d8283f7e89f332f.

When we revert the chain to retest the DIP3 deployment, this fork logic
can be removed again.

* Use quorumVvecHash instead of quorumHash to make null commitments unique

Implementation of https://github.com/dashpay/dips/pull/31

* Re-add quorum commitments after pruning mempool selected blocks

* Refactor CQuorumBlockProcessor::ProcessBlock to have less nested if/else statements

Also add BEGIN/END markers for temporary code.

* Add comments/documentation to LLMQParams

* Move code which determines if a commitment is required into IsCommitmentRequired

This should make the code easier to read and also removes some duplication.

The also changes the error types that are possible from 3 to 2 now. Instead
of having "bad-qc-already-mined" and "bad-qc-not-mining-phase", there is
only "bad-qc-not-allowed" now.

* Use new parameter from consensus parames for the temporary fork

Implement mt_pooled_secure_allocator and use it for BLS secure allocation (#2375)
* Add pooled_secure_allocator and mt_pooled_secure_allocator

* Use mt_pooled_secure_allocator for BLS secure allocation

The old solution relied on thread-local-storage and was thus not compatible
to libc6 2.11 (which is the minimum supported version we use).

Also, the old solution turned out to be erroneous. It would have crashed
or memory leaked when ownership of CBLSPrivateKey would be handled over
to another thread.

* Add new header files to Makefile.am

* Fix copyright headers of new files

* Bail out early from secure deallocation

* Clean up global BLS keys when shutting down
