Bump PROTOCOL_VERSION and DMN_PROTO_VERSION to 70213 (#2557)
* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION to 70213

This will disconnect all nodes from the old testnet chain when DIP3 gets
activated through BIP9.

Also update comments where 70212/70213 was referenced.

* Also bump MIN_PEER_PROTO_VERSION_DIP3 and MIN_PRIVATESEND_PEER_PROTO_VERSION

Add 5th denom, drop deprecated logic and bump min PS version (#2318)
* Bump PS
- add 5th denom (0.001)
- always allow OP_RETURN in PS collaterals
- collateral amount is always 1/10 of the smallest denom
- bump MIN_PRIVATESEND_PEER_PROTO_VERSION to 70211

* drop backward compatibility in dsa/dsq serialization

* Use GetSmallestDenomination() in GetCollateralAmount()

* bump MIN_PRIVATESEND_PEER_PROTO_VERSION to 70212

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

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

753b1e486b Eliminate remaining uses of g_connman in Dash-specific code. (#1635)
This monstrous change eliminates all remaining uses of
g_connman global variable in Dash-specific code.

Unlike previous changes eliminating g_connman use
that were isolated to particular modules, this one covers
multiple modules simultaneously because they are so interdependent
that change in one module was quickly spreading to others.

This is mostly invariant change that was done by
* changing all functions using g_connman to use connman argument,
* changing all functions calling these functions to use connman argument,
* repeating previous step until there's nothing to change.

After multiple iterations, this process converged to final result,
producing code that is mostly equivalent to original one, but passing
CConnman instance through arguments instead of global variable.

The only exception to equivalence of resulting code is that I had to
create overload of CMasternodeMan::CheckAndRemove() method without arguments
that does nothing just for use in CFlatDB<CMasternodeMan>::Dump() and
CFlatDB<CMasternodeMan>::Load() methods.
Normal CMasternodeMan::CheckAndRemove() overload now has argument of
CConnman& type and is used everywhere else.

The normal overload has this code in the beginning:

    if(!masternodeSync.IsMasternodeListSynced()) return;

Masternode list is not synced yet when we load "mncache.dat" file,
and we save "mncache.dat" file on shutdown, so I presume that it's OK
to use overload that does nothing in both cases.
