Add support to eliminate a context switch per crypto op when using the
software crypto device:
o record crypto device capabilities in each session id
o add a capability that indicates if the crypto driver operates synchronously
o tag the software crypto driver as operating synchronously
This commit also introduces crypto session id macros that cleanup their
construction and querying.
