f81ea67a08 Remove hashes from setAskFor (#1264)
We should remove hash from setAskFor when the message corresponding to previous inv arrives, otherwise it's stays there forever and setAskFor overflows (i.e. AskFor returns immediately without processing).

f995a264e2 Do not try to check or verify mns until synced to some stage (#1261)
Verification creates new conections, which we also use to sync but then we disconnect on ProcessMasternodeConnections every minute which at least could lead to excessive node load (for our peers). But could also interfere with sync process itself and we'd better keep them separate.

34fd8daf5a Fix sync issues (#1225)
* Store time we saw mnb last time, bump sync timeout
if we received seen mnb but we are too close to MASTERNODE_NEW_START_REQUIRED_SECONDS

* Reset blockchain sync status if new blocks were accepted during sync

* Add some debug log output

* wait for at least one new block to be accepted

* bump CGovernanceManager-Version

70b374062b [WIP] Few mn list sync changes (#1223)
* Few mn list sync changes:
- add more mn states
- only remove spent
- send mn ping in addition to mn announce on sync
- manage mn announces more carefully
- expire mns created from broadcasts with invalid ping
- old fWaitForPing logic for old nodes, should be helpful during migration period

This also adjusts active mn auto-start logic accordingly.

1c6c0d8b7e fix AskForMN (#1217)
Should also store/check node we asked for mn list entry, not outpoint only. This should help to get mn list in sync when some nodes refuse to answer thus blocking such requests for the same outpoint for the next 3h and increasing mn list inconsistency.

a0c93ebaa5 cleanup/fix includes: (#1214)
- some were not used, some were included twice, some were in the wrong place, some were missing (but it compiled because some were in the wrong place)
- organized a bit better, grouped dash specific includes in original bitcoin files, should save some time solving conflicts when/if merging patches later

17cebbed15 fix excessive banning, remove some redundant logic (#1172)
* Since we send all mnb's now regardless of mn state, ping check for sigTime being too old is obsolete (and wrong).
Also removing fRequireEnabled, this logic is deprecated too it seems.

* remove (pre-)enabled check in CMasternodeMan::Add

0600a6ce1a Fix (dead)locks (#1169)
* locks in PS

* lock in governance

* locks in IS

* lock in ProcessGetData

* locks in CMasternodeSync

* centralize mnodeman.Check call

* locks order in mnpayments

* use current block chainTip when possible (less locks)

* LOCK2 in CheckMnbAndUpdateMasternodeList, CheckAndUpdate, SendVerifyRequest

* LOCK(cs) is not needed here

* Decouple governance init actions from serialization
Should fix this:
```
Assertion failed: lock governance.cs not held in governance-classes.cpp:117; locks held:
cs_Shutdown  init.cpp:200 (TRY)

* PoSe changes:
- use helpers to alter nPoSeBanScore within predefined range only
- use nPoSeBanHeight instead of timeout of inactivity to ban masternodes till some block in the future (currently should block for the whole payment cycle)
- add log output on pose score increase in CheckSameAddr
