Drop glx_ansic.h wrapper and call malloc, realloc, free and str-funcs directly.

 commit 2d2d38d17cc2558f8a41166a4a1578bc4c663c37
 Author: Kristian Høgsberg <krh@redhat.com>
 Date:   Fri Mar 17 01:47:25 2006 +0000

        Check for glproto when building GLX and make sure we have at least 1.4.6.
        Drop glx_ansic.h wrapper and call xalloc, xrealloc, xfree and str-funcs
            directly.

     We don't check the glproto version as we know what it is (we have our own proto file).

     Furthermore, we skip the switch from --glX<func> -> x<func> and directly switch to
     <func> (e.g. __glXMalloc() -> malloc()).
