Change subject: Work around thread safety issues in the PBX core.
......................................................................


Patch Set 1:

I'll add that the ast_rd/wrlock_context()/ast_unlock_context() functions already are public and used outside of pbx core by some modules.  This patch just adds more instances of the same pattern.

Also the rd/wr lock has been a sham for a long time since they are actually using a mutex because the locks get reentrantly held.
