This sends all outputs in a wallet to a given address, alleviating
the difficulty people have had trying to send all monero but
being left with some small amount left.
Blockchain hashes and key images are flushed, and blocks are
pulled anew from the daemon.
The console command is shortened to match bc_height.
This should make it a lot easier on users who are currently
told to remove this particular cache file but keep the keys
one, etc, etc.
Daemon interactive mode is now working again.
RPC mapped calls in daemon and wallet have both had connection_context
removed as an argument as that argument was not being used anywhere.
wallet RPC now uses wallet2::create_transactions and wallet2::commit_tx instead
of wallet2::transfer. This made it possible to add the RPC call /transfer_split, which
will split transactions automatically if they are too large. The old call to
/transfer will return an error stating to use /transfer_split if multiple
transactions are needed to fulfill the request.
