Subject: Add mechanism to destroy mutexes.  Important on OS's where mutex initialization
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e15fd85727636627e0cc7d4fd2d5367e178e42cc;p=mesa.git

Add mechanism to destroy mutexes.  Important on OS's where mutex initialization
allocates memory (like FreeBSD).
