pefs and l2filter moved to github

I've just moved pefs and l2filter development to github. Hope it helps people to follow development.

pefs repository (github.com/glk/pefs) can be used to to compile and run pefs without applying any patches.

pefs changelog:

• support running on msdosfs
• enable dircache only on file systems that are known to support it
• add man page
• add pefs getkey command
• intial implementation of pefs PAM module

l2filter repository (github.com/glk/l2filter) contains only patches. There is fresh patch against 8-STABLE with some minor improvements comparing to 7-STABLE version. 9-CURRENT patch is a bit outdated at the moment, as I'm waiting for Luigi Rizzo to finish ipfw refactoring work first.
