- Removed -fno-strict-aliasing from the GCC flags for ZDoom and fixed the

issues that caused its inclusion. Is an optimized GCC build any faster
  for being able to use strict aliasing rules? I dunno. It's still slower
  than a VC++ build.
  
  I did run into two cases where TAutoSegIterator caused intractable problems
  with breaking strict aliasing rules, so I removed the templating from it,
  and the caller is now responsible for casting the probe value from void *.
- Removed #include "autosegs.h" from several files that did not need it
  (in particular, dobject.h when not compiling with VC++).
