Add a few more tests to FullBlockTestGenerator.

stuff.

Give Blocks/Transactions an idea of their optimally-encoded size.
...
In the case of Blocks/Transactions which are encoded using VarInts
which are not optimally encoded, we need to compare MAX_BLOCK_SIZE
with the optimally encoded size, not the actually encoded size.

Give VarInt a concept of originally serialized size.
...
VarInts have multiple encodings, and during parsing we need to know
the size of the actually encoded form, not the size of the optimal
encoding.

Make FullPrunedBlockStore/Chain upgrade-friendly.
...
This does several things to support the ability to upgrade from a
BlockChain to a FullPrunedBlockChain backed by the same
FullPrunedBlockStore:
* Add two methods to FullPrunedBlockStore to allow it to keep
track of two chain heads - one verified, one normal.
* Change preSetChainHead in AbstractBlockChain to doSetChainHead so
that FullPrunedBlockChain and BlockChain can set only the
appropriate chain head
* Add FullPrunedBlockStore.getOnceUndoableStoredBlock.
This allows a BlockChain to request only StoredBlocks which
were, at one point, associated with a StoredUndoableBlock,
effectively splitting FullPrunedBlockStore into two independent
BlockStores (one FullPruned, one normal).
* Add/use AbstractBlockChain.getStoredBlockInCurrentScope which
relies on the above additions to FullPrunedBlockStore to properly
utilize one FullPrunedBlockStore as two separate block stores
depending on the BlockChain instance used.
Note that this is not used everywhere in AbstractBlockChain as,
barring something being insanely broken, the prev block of a
block in current scope will be in current scope.

Some improvements to the network code:
...
- Delete the PeerGroupThread and replace it with a connectToAnyPeer() method. Getting connected to the network is now significantly faster as there is no sleep-wait loop between connections.
- Delete the connectionTimeMillis param to the PeerGroup constructors.
- Expose the PeerGroup c'tor that lets you specify the ClientBootstrap and expose a utility method to make one. This means users can now customize TCP options directly.
- PeerGroup.setMaxConnections() now actually creates or tears down connections to meet the new required number, if the peer group is running.
- Update the PeerMonitor so there's a spinner that lets you add or remove peers. Connecting and version handshaking is very fast now.
- Misc changes and fixes.
