gzdoom-gles/src/am_map.cpp
Christoph Oelckers 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
