c9d2745188 Use BLS keys for the DIP3 operator key (#2352)
* Use BLS keys for operator keys

* Add "bls generate" RPC to generate BLS keys

* Use unique_ptr to store blsKeyOperator and blsPubKeyOperator

Needed because the Chia BLS library crashes when keys are created before
the library is initialized, even if keys are not used. This is the case here
as we have static instances here.

* Remove unnecessary CheckSignature calls

This seems to be some garbage I left in by mistake.

* Fixed review comments

* Fix rpc help for operator keys

All keys that are used as examples are random. None of the secret keys
belongs to any of the public keys.

* Use .GetHash() instead of ::SerializeHash() for BLS pubkeys in txmempool.cpp

* Rename mapProTxBlsPubKeys to mapProTxBlsPubKeyHashes

Pick rounds with the most inputs available to mix first (#2278)
* Alternative solution: pick rounds with the most inputs available to mix first

* randomly skip some inputs when we have at least one of this denom already

* More randomization in PrepareDenominate

* fix `vecSteps[nBit] >= 1 ?` and adjust speed/privacy ratio for more speed i.e. `GetRandInt(5) == 0`

* fix typos

* no comments

89f744d064 pack of small cleanup fixes / optimizations (#2334)
* remove vector, extra loop in cleanup function

This commit removes 2 loops and a vector which I don't believe are necessary in
CMasternode::FlagGovernanceItemsAsDirty. I could be missing something, but
can't think of any good reason why this was implemented this way.

* use range operator to range over vectors

* remove deprecated wire message types

* mn: simplify govobj map mgmt a bit

* remove extra semicolons

* invert if/else condition and drop else

* remove if/else logic from Qt

This is the entire purpose of the Get<X>String methods on MNP class.

* Revert "remove deprecated wire message types"

This reverts commit 9de88a3fda999555c00cb829d60e322b2fd3800d.

* Revert "remove if/else logic from Qt"

This reverts commit c0f43c9b85274b13a3ac9625775817bc5b53bb9d.

Add more variance to coin selection in PS mixing (#2261)
* Lean towards "from high to low" branch but still mix via "from low to high" one someties

* Try to mix non-duplicate txids only

* Lean towards edges but still mix starting from the middle sometimes

If failed when started from the middle try mixing from the edges right away.

Note: liqudity providers always start from 0

* map -> set

* Refactor nRoundStart calculations

Split PS into Manager and Session and allow running multiple mixing sessions in parallel (client side) (#2203)
* Split PS into Manager and Session

* Adjust log messages accordingly

* add -privatesendsessions cmd-line option

* address review comments

* bump MAX_OUTBOUND_MASTERNODE_CONNECTIONS to 30

+10 for parallel mixing

* protect vecSessions

* constructors

* Rewrite CMasternodeMan::ProcessMasternodeConnections() to use CPrivateSendClientManager::GetMixingMasternodesInfo().

This should solve potential deadlock cs_vecqueue vs cs_vNodes.

* Drop no longer used IsMixingMasternode()

* lock cs_wallet when mixing uses balance related functions

25545fc1e7 Split keyIDMasternode into keyIDOwner/keyIDOperator/keyIDVoting (#2248)
* Split keyIDMasternode into keyIDOwner/keyIDOperator/keyIDVoting

keyIDOwner is the key used for things which should stay in control of the
collateral owner, like proposal voting.

keyIDOperator is the key used for operational things, like signing network
messages, signing trigger/watchdog objects and trigger votes.

keyIDVoting is the key used for proposal voting

Legacy masternodes will always have the same key for all 3 to keep
compatibility.

Using different keys is only allowed after spork15 activation.

* Forbid reusing collateral keys for operator/owner keys and vice versa

* Bump SERIALIZATION_VERSION_STRING in CMasternodeMan

532b9fa3db Use OpenNetworkConnection instead of calling ConnectNode directly in Dash code (#1857)
ConnectNode is meant to be private and should not be leaked outside of
CConnman. This leaking resulted in multiple problems with AddRef/Release
behaviour. We use OpenNetworkConnectio/OpenMasternodeConnection from now on
and use appropriate ForNode calls to access the CNode* instance.

This commit also changes the behaviour for already connected nodes which
are afterwards requested for a masternode connection. We don't set
fMasternode=true anymore on such nodes, which means it won't be auto
disconnected anymore from ProcessMasternodeConnections.
