Create getaddressinfo RPC and deprecate parts of validateaddress

Moves the parts of validateaddress which require the wallet into getaddressinfo
which is part of the wallet RPCs. Mark those parts of validateaddress which
require the wallet as deprecated.

Validateaddress will  call getaddressinfo
for the data that both share for right now.

Moves IsMine functions to libbitcoin_common and then links libbitcoin_wallet
before libbitcoin_common in order to prevent linker errors since IsMine is no
longer used in libbitcoin_server.
