8ea1bd0f55 remove unused method GetObjectSubtype (#1914)
I believe this was stubbed to eventually read the string in the 1st
field of the inner array in the gobject JSON. Currently only Sentinel
uses this and I would like to move to just a single JSON object, so
don't think this is necessary any longer.

Various fixes and refactoring for Cache*Map classes (#1896)
* CacheMap::Insert should not update existing item, should return `false`

* Use `emplace` operator instead of `[]` to add new items in Cache*Map implementation

* Use prefix cm/cmm for CacheMap/CacheMultiMap maps respectively to distinguish them from each other and from std::map-s

* Avoid excessive processing of already known valid votes

Also prettify debug log output a bit

* Drop nCurrentSize from Cache*Map classes

Use `size()` and `empty()` of std classes instead, they have constant complexity since c++11

* Do not create an explicit iterator if it's never used later (in Cache*Map)

* Do not prune last item in CacheMultiMapInsert when trying to insert a duplicate one

7765c87e79 Remove nType and nVersion from Dash related serialization code
Also remove bogus "nVersion = this->nVersion" assignments. These were
leftovers from old times.

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.

f1ee9d9c71 Change governance sync process (#1265)
* On gov sync first sync objs, then ask for votes on per-obj basis from different peers.

This should help to sync obj list initially and split the load among many peers. Also adds ability to catch up votes later after the sync.

* ask for all objects, do this in cycles

* Fix Sync() code, better readability

* ask multiple nodes at once when possible, perf boost for large numper of objs

* Addressed comments: pass reference, more peer version check

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
