Add a c library that has some primitive cryptographic functions needed
for working with adaptor signatures.

	get transaction development details from monerod
	including tx lock time; which is different from
	'locked'/'unlocked' which refer to when a tx
	has 10 confirmations. Tx locktime can be any
	number of blocks in the future.

	- Rename monero_functions.inc -> monero_functions
	- Tidy extra whitespace at eol for harness.sh &
	  monero_functions.

	New monero-wallet-rpc server with no attached wallet. This is
 	for programmatically creating/generating and using a new wallet.

	The wallet will be generated in "own" dir but can be named what-
	ever you need: "alice", "Bob", etc.
