No change in behavior
No change in behavior. New function is split from CRPCTable::execute and used in the next commit.
CRPCTable::dumpArgMap currently works by casting RPC command unique_id integer field to a function pointer, and then calling the function. The unique_id field wasn't supposed to be used this way (it's meant to be used to detect RPC aliases), and this code segfaults in the rpc_help.py test in multiprocess PR bitcoin#10102 because wallet RPC functions aren't directly accessible from the node process. Fix this by adding a new GET_ARGS request mode to retrieve argument information similar to the way the GET_HELP mode retrieves help information.
