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

ef8dfe4 Prevent block.nTime from decreasing (Mark Friedenbach)

ef8dfe41d1 Prevent block.nTime from decreasing
Under some circumstances it is possible for there to be a significant,
discontinuous jump in a node's clock value. On mining nodes, this can
result in block templates which are no longer valid due to time-based
nLockTime constraints. UpdateTime() is modified so that it will never
decrease a block's nLockTime, thereby preventing such invalidations.

c8b74258ba setgenerate creates multiple blocks in -regtest mode
I'm writing some wallet regression tests using -regtest mode, and
need to generate an initial multi-hundred-block chain. Repeatedly
calling setgenerate to generate one block is slow and doesn't
work properly, because block creation happens asynchronously.

This adds two features to setgenerate in -regtest mode:

1) Instead of being interpreted as number of threads to start, the
third argument is the number of blocks to generate.

2) setgenerate will not return until the block creation threads
have created the requested number of blocks.
