SASL 2.1.27 rc5

[Ken Murchison]

Alexy and I had a Google hangout conversation last week and we are 
committed to resolving the GSSAPI issue(s) and any other non-invasive 
issues/pull-requests within the next month. Probably one more 
(short-lived) release candidate with the final 2.1.27 released by Christmas.

Please update any existing issues that you feel are critical to the 
2.1.27 release.
