088525bde3 Multiple fixes for LLMQs and BLS batch verification (#2674)
* Check aggPubKey for IsValid() instead of aggSig

aggSig is not reliable here as it might already be initialized by the
previous message.

* Significantly reduce sleep time for each DKG phase

Turns out the DKG is much faster then expected, and waiting multiple
minutes for each phase in a devnet is not much fun.

* Correctly use SIGN_HEIGHT_OFFSET when checking for out of bound height

* Introduce startBlockHeight to make things more explicit

18950f923e Optimize DKG debug message processing for performance and lower bandwidth (#2672)
* Allow sub-batch verification in CBLSInsecureBatchVerifier

* Implement batch verification of CDKGDebugStatus messages

* Use uint8_t for statusBitset in CDKGDebugMemberStatus and CDKGDebugSessionStatus

No need to waste one byte per member and per LLMQ type.

* Reserve 4k of buffer for CSerializedNetMsg buffer

Profiling has shown that a lot of time is spent in resizing the data
vector when large messages are involved.

* Remove nHeight from CDKGDebugStatus

This field changes every block and causes all masternodes to propagate
its status for every block, even if nothing DKG related has changed.

* Leave out session statuses when we're not a member of that session

Otherwise MNs which are not members of DKG sessions will spam the network

* Remove receivedFinalCommitment from CDKGDebugSessionStatus

This is not bound to a session and thus is prone to spam the network when
final commitments are propagated in the finalization phase.

* Add "minableCommitments" to "quorum dkgstatus"

* Hold cs_main while calling GetMinableCommitment

* Abort processing of pending debug messages when spork18 gets disabled

* Don't ask for debug messages when we've already seen them

"statuses" only contains the current messages but none of the old messages,
so nodes kept re-requesting old messages.

Fix LLMQ related test failures on Travis (#2666)
* Use fast_dip3_enforcement instead of fast_dip3_activation

DashTestFramework was refactored before ChainLocks got merged, causing tests
to fail now.

* Move updating of DKG debug status into WaitForNextPhase

Otherwise callers of the RPCs might believe that the next phase has already
started and start producing more blocks, which would then cancel the
current session if it happens faster than the phase handler thread can
progress to the next phase.

Bring back ResetLocalSessionStatus call (#2639)
It was dropped accidentally on refactoring.

A couple of fixes/refactorings for CDKGSessionHandler (#2637)
* Fix confusion: `quorumHash` is both a class member and an argument of a function

Rename `height` too while at it

* Make sure height and hash we pass to InitNewQuorum are related

* Don't update expectedQuorumHash, make it const

This also streamlines logic a bit

* Compact phase calculation

* Decouple invCs and cs_vPendingMasternodes

Not an issue atm but we'd better avoid any potential interlocking if possible

* wrap `%` in `()`
