Enrico Weigelt, metux IT consult 016f62baad glamor: BUG_* checks on NULL atlas 
If this happens, we really have a bug, so better spit out a warning
instead of just segfault'ing.

Enrico Weigelt, metux IT consult b0c9e95a61 glamor: BUG_RETURN*() on pixmap private data 
Usually shouldn't happen trying to accessing pixmap's glamor private
data w/o having it initialized first. But just in case there's some
subtle bug, adding extra checks, which don't cost us much.

Enrico Weigelt, metux IT consult faef79be75 glamor: protect from NULL return of GetPictureScreenIfSet() 
GetPictureScreenIfSet() is designed that NULL can be returned.
Even though it should not happen in this particular case,
better be prepared for that, instead of just segfault'ing.

Enrico Weigelt, metux IT consult 5fd11ec4a6 glamor: NULL-protect GLAMOR_PIXMAP_PRIV_HAS_FBO() 
It could potentially be called with NULL pointer, but can't handle it,
so when that happens, it's a bug. Adding a BUG_RETURN_VAL() call here,
so it's giving us a hint where to look at.

Enrico Weigelt, metux IT consult 269cd0f8ac xkb: maprules: fix potential NULL pointer dereference warnings 
Even though the cases might be hypothetical, it's still better having some
tiny extra checks (that might be even optimized-out) and reduce the analyzer
noise a bit.
