Enrico Weigelt, metux IT consult be470cbf46 (!1967) dix: protect from pScreen->SetCursorPosition == NULL
It's safer not relying on all ScreenProc's actually filled.

Be more cautious on possible NULL pointers or not yet registered

Even though it *should* never be actually hit, it's still safer

Safer (and easier to understand) if we look at the result pointer

Enrico Weigelt, metux IT consult 80accc08cb (!1969) xfree86: loader: add assert() in LoadModule()
There's (remote) chance that the (internal) module name could become
NULL (eg. allocation failure). Even though chances to hit it are very
low, it's still better to have a check here (that doesn't cost us much),
just in case. Assert fail is still better than segfault, since we're
at least getting some hint what might have happened.

Enrico Weigelt, metux IT consult 873f4c36e9 (!1969) xfree86: parser: check for alloc failure and possible NULL pointers
Adding paranoid extra checks against allocation failure and NULL pointers.
Even though might not be actually hit in practise, it's still better to
be cautious, just in case. And reducing analyzer noise this way.

Enrico Weigelt, metux IT consult 0f7fb5e338 (!1969) xfree86: x86emu: add extra assert()'s
The analyzer warnings (possible NULL dereference) are probably just
false alarms. But for safety adding assert()'s, which don't cost us
anything in non-debug builds.
