bb20b4e7b5 Few cleanups after backporting (#1903)
* Remove remains of workaround that was needed while backporting

* Add missing closing round bracket to help string

* Remove now unnecessary .encode() calls in wallet.py

Now that we only support python3, we can fix this TODO.

Drop BOOST_FOREACH and use references in loops (const ref where applicable, Dash code only) (#1899)
* Drop BOOST_FOREACH in Dash-specific code (only), no changes in behavior

* Use references in loops (use const references where applicable) in Dash-specific code (only)

And adjust related code to make it compilable.

* Loop through nodes via connman.ForEachNode in dsq Relay instead of creating a copy

99b2789a73 Fix DeserializeAndCheckBlockTest benchmark and store hashDevnetGenesisBlock in consensus (#1888)
* Use Dash block for DeserializeAndCheckBlockTest

Replaced Bitcoin block with the largest Dash block I could find on mainnet.

* Store hashDevnetGenesisBlock in Consensus::Params

Remove the need for chainparams to be available when the devnetGenesis hash
is needed. Fixes a crash in CheckBlockHeader() when called from benchmarking
code, which does not initialize the Params() function.

cd9c6994c2 Implement named devnets (#1791)
* Initial devnet

* Move genesis block adding into its own method

* Introduce -allowprivatenet to lift limitation on RFC1918 addresses

Normally, RFC1918 (192.168.x.x/10.x.x.x/...) addresses are not allowed
to be relayed. Also, masternodes won't start when the address is considered
invalid.

This is needed to test local devnet or regtest based networks.

* Lift the requirement of minimum MN age for regtest/devnet

* Implement named devnets

This allows the creation of multiple independent devnets. Each one is
identified by a name which is hardened into a "devnet genesis" block,
which is automatically positioned at height 1. Validation rules will
ensure that a node from devnet=test1 never be able to accept blocks
from devnet=test2. This is done by checking the expected devnet genesis
block.

The genesis block of the devnet is the same as the one from regtest. This
starts the devnet with a very low difficulty, allowing us to fill up
needed balances for masternodes very fast.

Also, the devnet name is put into the sub-version of the VERSION message.
If a node connects to the wrong network, it will immediately be disconnected.

* Allow to select multiple addresses from the same group in devnet/regtest

The selection code normally only allows to select addresses from the same
group (e.g. 192.168.x.x) once. This results in connecting to only a single
node in devnet/regtest.

* Show the devnet name in the title bar and on the loading screen

* Add AllowMultipleAddressesFromGroup to chainparams and use it in net.cpp

* Remove unused/unneeded scripts from devnet geneses creation

1. OP_RETURN not needed in input script of devnet genesis
2. genesisOutputScript was unused

* Fix copy/paste error in -allowprivatenet description

* Improve -devnet parameter error handling

- Only allow one of -devnet, -regtest or -testnet
- Only allow -devnet=name to be specified once

* Use different datadir for each devnet

* Fix `devnet-devnet` issue

* Fix devnet splashscreen (should use testnet img)

* Avoid passing devNetName around (most of the time)

* Remove nMaxTipAge from CDevNetParams

masternode sync and it gives the impression of being stuck after the block
chain sync is done.

* Don't include chainparams.h in sendcoinsdialog.cpp

This was just a remainder of a backported PR which meant to change some
calculation in this file which does not apply to Dash.

* Also check for fNetworkActive in ConnectNode

Pull request description:

  Fixes https://github.com/bitcoin/bitcoin/issues/10291, https://github.com/bitcoin/bitcoin/issues/11265

  progressDelta may be 0 (or even negative according to 11265), this checks for that and prints unknown if it is, because we cannot calculate an estimate for the time remaining (would be infinite or negative).

4f0618ae8a Fix sync issues (#1599)
- add `MASTERNODE_SYNC_WAITING` sync state/asset and initial timeout
- wait for block headers to be downloaded (new signal `AcceptedBlockHeader`)
- wait for blocks to reach best headers tip before switching to masternode list sync (new signal `NotifyHeaderTip`)
- switched sync from `UpdatedBlockTip` to a combination of `AcceptedBlockHeader` and `NotifyHeaderTip`
- all blockchain-related bumps should take place only while we are still syncing blockchain, should be no such bumps after that

ccee103a0e Backport "assumed valid blocks" feature from Bitcoin 0.13 (#1582)
* IBD check uses minimumchain work instead of checkpoints.

This introduces a 'minimum chain work' chainparam which is intended
 to be the known amount of work in the chain for the network at the
 time of software release.  If you don't have this much work, you're
 not yet caught up.

This is used instead of the count of blocks test from checkpoints.

This criteria is trivial to keep updated as there is no element of
subjectivity, trust, or position dependence to it. It is also a more
reliable metric of sync status than a block count.

* Remove GetTotalBlocksEstimate and checkpoint tests that test nothing.

GetTotalBlocksEstimate is no longer used and it was the only thing
 the checkpoint tests were testing.

Since checkpoints are on their way out it makes more sense to remove
 the test file than to cook up a new pointless test.

# Conflicts:
#	src/Makefile.test.include
#	src/test/Checkpoints_tests.cpp

* IsInitialBlockDownload no longer uses header-only timestamps.

This avoids a corner case (mostly visible on testnet) where bogus
 headers can keep nodes in IsInitialBlockDownload.

* Delay parallel block download until chain has sufficient work

nMinimumChainWork is an anti-DoS threshold; wait until we have a proposed
tip with more work than that before downloading blocks towards that tip.

* Add timeout for headers sync

At startup, we choose one peer to serve us the headers chain, until
our best header is close to caught up.  Disconnect this peer if more
than 15 minutes + 1ms/expected_header passes and our best header
is still more than 1 day away from current time.

* Introduce assumevalid setting to skip presumed valid scripts.

This disentangles the script validation skipping from checkpoints.

A new option is introduced "assumevalid" which specifies a block whos
 ancestors we assume all have valid scriptsigs and so we do not check
 them when they are also burried under the best header by two weeks
 worth of work.

Unlike checkpoints this has no influence on consensus unless you set
 it to a block with an invalid history.  Because of this it can be
 easily be updated without risk of influencing the network consensus.

This results in a massive IBD speedup.

This approach was independently recommended by Peter Todd and Luke-Jr
 since POW based signature skipping (see PR#9180) does not have the
 verifiable properties of a specific hash and may create bad incentives.

The downside is that, like checkpoints, the defaults bitrot and older
 releases will sync slower.  On the plus side users can provide their
 own value here, and if they set it to something crazy all that will
 happen is more time will be spend validating signatures.

Checkblocks and checklevel are also moved to the hidden debug options:
 Especially now that checkblocks has a low default there is little need
 to change these settings, and users frequently misunderstand them as
 influencing security or IBD speed.  By hiding them we offset the
 space added by this new option.

* Add consensusParams to FindNextBlocksToDownload

* Adjust check in headers timeout logic to align with 144 blocks in Dash

105713c10a Sync overhaul (#1564)
* Change sync process:
- IsBlockchainSynced(): drop CheckNodeHeight() and all complicated code, use fInitialDownload in UpdatedBlockTip() to switch initial states
- ProcessTick(): detect sleep mode like it was in IsBlockchainSynced(), not by number of masternodes

* Changes for sync in governance:
- do not keep sync alive on ConfirmInventoryRequest()
- skip some governance actions until we are synced to some level

* do not run CMasternodeMan::UpdateLastPaid() until winners list is synced

* start syncing mn list on the same node right after requesting sporks

* replace nTimeLast<Asset> with the unified nTimeLastBumped, bump on UpdatedBlockTip

* fix comments and LogPrintf-s

* remove excessive MASTERNODE_SYNC_IBD

* a bit more descriptive BumpAssetLastTime in few cases

df6d458b85 Backport Bitcoin PR#9260: Mrs Peacock in The Library with The Candlestick (killed main.{h,cpp}) (#1566)
* Remove orphan state wipe from UnloadBlockIndex.

As orphan state is now "network state", like in
d6ea737be1,

UnloadBlockIndex is only used during init if we end up reindexing
to clear our block state so that we can start over. However, at
that time no connections have been brought up as CConnman hasn't
been started yet, so all of the network processing state logic is
empty when its called.

* Move network-msg-processing code out of main to its own file

* Rename the remaining main.{h,cpp} to validation.{h,cpp}
