Introduce CDSNotificationInterface - validation interface to listen to tip updates and trigger updates in DS, payments and budgets. Should significantly reduce number of references to chainActive.Tip() i.e.we should have less cs_main in dash-darksend thread and potential deadlocks.

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.

// CValidationInterface
Fix sync issues (#1599) - add `MASTERNODE_SYNC_WAITING` sync state/asset and initial timeout - wait for block headers to be downloaded (new signal `AcceptedBlockHeader`) - wait for blocks to reach best headers tip before switching to masternode list sync (new signal `NotifyHeaderTip`) - switched sync from `UpdatedBlockTip` to a combination of `AcceptedBlockHeader` and `NotifyHeaderTip` - all blockchain-related bumps should take place only while we are still syncing blockchain, should be no such bumps after that
