autofs-5.1.1 - fix sasl connection concurrancy problem
From: Ian Kent <raven@themaw.net>
After using the contributed Cyrus SASL code in autofs for years I've
finally looked at the Cyrus SASL C API RFC only to find that the
library isn't thread safe unless a connection context per thread is
used, similar to the LDAP library.
To be fair this code originated prior to the threaded version of
autofs so it's my bad I didn't check.
But having seen this I have no choice but to make the sasl context
per thread not per autofs lookup context.
Also extend the mutual exclusion even further.
