rpc/*: auth-header changes
Introduce another authentication header which can now send more data. This is useful because this data can be common for all the fops, and we don't need to change all the signatures. As part of this, made rpc-clnt.c little more modular to support multiple authentication structures. stack.h changes are placeholder for the ctime etc, can be moved later based on need. updates #384 Change-Id: I6111c13cfd2ec92e2b4e9295896bf62a8a33b2c7 Signed-off-by: Amar Tumballi <amarts@redhat.com>
