MFC r261251:
Prevent races in accesses of the software crypto session array.
swcr_newsession can change the pointer for swcr_sessions which races with
swcr_process which is looking up entries in this array.
Add a rwlock that protects changes to the array pointer so that
swcr_newsession and swcr_process no longer race.
