25fa44d5a9 fix DIP0001 implementation (#1639)
According to DIP0001 description we should be using payment queue to select current masternode:
>As a block is mined the version number is determined by the miner who mined it and the masternode that is selected for that block.
>...
>The selection of a round consisting of 4032 blocks is made based on masternodes not being randomly selected, rather they are in a queue.

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.

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.

eaf57b3fb7 Implemented masternodebroadcast
This set of rpc commands provide an ability to create masternode broadcast messages offline
and relay them from online node later (messages expire in ~1 hour).

Arguments:
1. command        (string or set of strings, required) The command to execute
2. passphrase     (string, optional) The wallet passphrase
Available commands:
  create-alias  - Create single remote masternode broadcast message by assigned alias configured in masternode.conf
  create-all    - Create remote masternode broadcast messages for all masternodes configured in masternode.conf
  decode        - Decode masternode broadcast message
  relay         - Relay masternode broadcast message to the network

Closes #741

eeb53b9682 Vastly faster syncing process / small budget system changes
- Syncing process is now event based, rather than timeout based. This means the system can tell when it's done with each step and moves on between phases much faster. In initial testing it seems to be about 10-15x faster and has synced everytime successfully.
- Please remove print debugging when the syncing system is proven to be debugged.
