1b88052bba - started refactoring ZatPoint calls which need to be portal aware.
To summarize, anything that just works with map geometry doesn't need to bother, as does the renderer. (i.e. nearly all r_* files, p_floor.cpp, p_ceiling.cpp et.al)
But all calls that are somehow related to actor positions need to be made aware of potential portal transitions:

 * added FloorAtPoint, CeilingAtPoint and PlaneAtPoint methods to sector_t, which can be used to calculate a plane's height with relation to a given actor, even if that actor is on the other side of a portal.
 * added HighestCeilingAt and LowestFloorAt methods which traverse all ceiling/floor portals until they find an impassable plane.

6adb069506 - rewrote p_local.h so that it doesn't pull in the entire bunch of headers.
This was to resolve some circular dependencies with the portal code.
The most notable changees:

 * FTextureID was moved from textures.h to doomtype.h because it is frequently needed in files that don't want to do anything with actual textures.
 * split off the parts from p_maputl into a separate header.
 * consolidated all blockmap related data into p_blockmap.h
 * split off the polyobject parts into po_man.h

344dda4a1a - Replaced toint/quickertoint with the portable routines from xs_Float.h. The
former used fistp, which is not portable across platforms, so cannot be
  used in the play simulation. They were only suitable for the renderer.
  xs_Float.h also has a very fast float->fixed conversion, so FLOAT2FIXED
  uses that now.
  (And I also learned that the FPU's round to nearest is not the rounding I
  learned in grade school but actually Banker's Rounding. I had no idea.)
  (Also, also, the only thing that could have made quickertoint faster than
  toint was that it stored a 32-bit int. I never timed them, and I doubt in
  practice there was any real difference between the two.)
- Changed atan2f to atan2. Using floats is not a win, because the result is
  returned as a double on the x87 stack, which the caller then needs to cast
  down to a float using fst/fld.

3f003e06db - Replaced the use of autoconf's WORDS_BIGENDIAN with __BIG_ENDIAN__, since
latter comes predefined by GCC.

00b21e4b96 - Apparently, YASM is not a suitable substitute for NASM when doing Win32 builds.
- Removed extraneous printf parameter for Texman.Init startup message.
- Added newlines to the ends of a few headers that were missing them.
- Fixed more GCC errors/warnings.
