Amar Takhar 774fb0f674 Fix all the headers in *., this includes:
* Wrapping all headers that are in agi_pre.h with AGI_PRE.
  * Sorting alphabetically.
  * Same operation as r3515.

Note: This is broken when precompiled headers are not in use, I'll fix that after this commit so the two changes don't get jumbled up.

Originally committed to SVN as r3525.
