Subject: xlib: switch to c11 mutex functions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2706db701d6217d245325f90f014233ff40ba18c;p=mesa.git

xlib: switch to c11 mutex functions

The _glthread_LOCK/UNLOCK_MUTEX() macros are just wrappers around
the c11 mutex functions.  Let's start getting rid of those wrappers.
