GLX: fix out-of-bounds memory issue in indirect glAreTexturesResident()
See bug 18445. When getting array results, __glXReadReply() always reads a multiple of four bytes. This can cause writing to invalid memory when 'n' is not a multiple of four. Special-case the glAreTexturesResident() functions now. To fix the bug, we use a temporary buffer that's a multiple of four bytes in length. NOTE: this commit also reverts part of commit 919ec22ecf72aa163e1b97d8c7381002131ed32c (glx/x11: Added some #ifdef GLX_DIRECT_RENDERING protection) which directly edited the indirect.c file rather than the python generator! I'm not repairing that issue at this time.
