0e689341d2 Implement Governance ZMQ notification messages (#2160)
* fix whitespace

* added zmq stuff for governance objects and votes
it seems that zmq is currently not in a working state, need to figure that out.

Need to:
plug in the new methods added
possibly plug in the old methods, as it doesn't look like they are.

* formatting fix. Will probably need to revert for this PR

* continue linking new zmq messages in

* added comment, might need to revert

* fixes error of it not knowing about the classes

* Actually link in, all new govobjects and govvotes should be broadcast over zmq now.

* fix compile error, forgot to change params when copying

* fix compile error

* add imports to the header files in zmqconfig.h

* fixing linking(i think) error

* Revert "added comment, might need to revert"

4f0618ae8a 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

a3c8cb20df Backport Bitcoin PR#8865: Decouple peer-processing-logic from block-connection-logic (#1556)
* Make validationinterface.UpdatedBlockTip more verbose

In anticipation of making all the callbacks out of block processing
flow through it. Note that vHashes will always have something in it
since pindexFork != pindexNewTip.

* Remove duplicate nBlocksEstimate cmp (we already checked IsIBD())

* Remove CConnman parameter from ProcessNewBlock/ActivateBestChain

* Remove SyncWithWallets wrapper function

* Move net-processing logic definitions together in main.h

* Use CValidationInterface from chain logic to notify peer logic

This adds a new CValidationInterface subclass, defined in main.h,
to receive notifications of UpdatedBlockTip and use that to push
blocks to peers, instead of doing it directly from
ActivateBestChain.

* Always call UpdatedBlockTip, even if blocks were only disconnected

* Use BlockChecked signal to send reject messages from mapBlockSource

a9d771e497 Backport Bitcoin PR#8085: p2p: Begin encapsulation (#1537)
* net: move CBanDB and CAddrDB out of net.h/cpp

This will eventually solve a circular dependency

* net: Create CConnman to encapsulate p2p connections

* net: Move socket binding into CConnman

* net: move OpenNetworkConnection into CConnman

* net: move ban and addrman functions into CConnman

* net: Add oneshot functions to CConnman

* net: move added node functions to CConnman

* net: Add most functions needed for vNodes to CConnman

* net: handle nodesignals in CConnman

* net: Pass CConnection to wallet rather than using the global

* net: Add rpc error for missing/disabled p2p functionality

* net: Pass CConnman around as needed

* gui: add NodeID to the peer table

* net: create generic functor accessors and move vNodes to CConnman

* net: move whitelist functions into CConnman

* net: move nLastNodeId to CConnman

* net: move nLocalHostNonce to CConnman

This behavior seems to have been quite racy and broken.

Move nLocalHostNonce into CNode, and check received nonces against all
non-fully-connected nodes. If there's a match, assume we've connected
to ourself.

* net: move messageHandlerCondition to CConnman

* net: move send/recv statistics to CConnman

* net: move SendBufferSize/ReceiveFloodSize to CConnman

* net: move nLocalServices/nRelevantServices to CConnman

These are in-turn passed to CNode at connection time. This allows us to offer
different services to different peers (or test the effects of doing so).

* net: move semOutbound and semMasternodeOutbound to CConnman

* net: SocketSendData returns written size

* net: move max/max-outbound to CConnman

* net: Pass best block known height into CConnman

CConnman then passes the current best height into CNode at creation time.

This way CConnman/CNode have no dependency on main for height, and the signals
only move in one direction.

This also helps to prevent identity leakage a tiny bit. Before this change, an
attacker could theoretically make 2 connections on different interfaces. They
would connect fully on one, and only establish the initial connection on the
other. Once they receive a new block, they would relay it to your first
connection, and immediately commence the version handshake on the second. Since
the new block height is reflected immediately, they could attempt to learn
whether the two connections were correlated.

This is, of course, incredibly unlikely to work due to the small timings
involved and receipt from other senders. But it doesn't hurt to lock-in
nBestHeight at the time of connection, rather than letting the remote choose
the time.

* net: pass CClientUIInterface into CConnman

* net: Drop StartNode/StopNode and use CConnman directly

* net: Introduce CConnection::Options to avoid passing so many params

* net: add nSendBufferMaxSize/nReceiveFloodSize to CConnection::Options

* net: move vNodesDisconnected into CConnman

* Made the ForEachNode* functions in src/net.cpp more pragmatic and self documenting

* Convert ForEachNode* functions to take a templated function argument rather than a std::function to eliminate std::function overhead

* net: move MAX_FEELER_CONNECTIONS into connman

Regression test for ResendWalletTransactions
Adds a regression test for the wallet's ResendWalletTransactions function, which uses a new, hidden RPC command "resendwallettransactions."

I refactored main's Broadcast signal so it is passed the best-block time, which let me remove a global variable shared between main.cpp and the wallet (nTimeBestReceived).

I also manually tested the "rebroadcast unconfirmed every half hour or so" functionality by:

1. Running bitcoind -connect=0.0.0.0:8333
2. Creating a couple of send-to-self transactions
3. Connect to a peer using -addnode
4. Waited a while, monitoring debug.log, until I see:
```2015-03-23 18:48:10 ResendWalletTransactions: rebroadcast 2 unconfirmed transactions```

One last change: don't bother putting ResendWalletTransactions messages in debug.log unless unconfirmed transactions were actually rebroadcast.
