- Multiple PEB/TEB creation fixes:

Browse source 
- Set up PEB and TEB under SEH to handle possible paging errors (which are legitimate).
  - Also touch the image under SEH to handle image paging errors (also legitimate).
  - Should avoid kernel panics in cases where the executable is damaged, invalid, or impossible to page in.
  - Initialize more PEB fields.
  - Add new INITIAL_PEB structure to support fork() in the future. Also fixes the fact we don't create a PEB for the system process anymore.
  - Create PEB while attached to the process.
  - Handle UP-only images, and set correct affinity mask in the PEB.
  - Set session ID instead of session structure (currently zero).
  - Set correct TIB version in the TEB. Due to a historical oddity, the NT TIB identifies itself as '0x1e00', which is 30 shifted 8 bits. 30 is the version identifier of OS/2 3.0, the original 32-bit target of the Windows NT effort.
  - Handle initial TEB correctly for fork().
  - Move AWE APIs to procsup.c instea of section.c since they are unrelated.
  - Move the rewritten PEB/TEB functions to ARM3's procsup.c.
