Disallow using addresses in createmultisig

Browse Source 
Make createmultisig only accept public keys with the old functionality
marked as deprecated.

Splits _createmultisig_redeemscript into two functions, one for
getting public keys from UniValue and one for getting addresses
from UniValue and then their respective public keys. The one for
retrieving address's public keys is located in rpcwallet.cpp

Changes addwitnessaddress's output to be a JSON object with
two fields, address and redeemscript.

Adds a test to deprecated_rpc.py for testing the deprecation.

Update the tests to use addwitnessaddress or give only public keys
to createmultisig. Anything that used addwitnessaddress was also
updated to reflect the new API.
