   Migrate ntoskrnl to PSEH 2.0. The code should speak for itself

modified   ntoskrnl/ex/atom.c
   _SEH_LEAVE was used improperly in NtQueryInformationAtom. As a free bonus, the upgrade to PSEH 2.0 (and to _SEH2_LEAVE) fixes the potential bug

modified   ntoskrnl/fsrtl/fastio.c
   Corrected exception filter logic

modified   ntoskrnl/include/internal/ex.h
   Goodbye _SEH_ExSystemExceptionFilter, you won't be missed

modified   ntoskrnl/include/internal/ntoskrnl.h
   Don't FORCEINLINE functions that use SEH, it's bad form and the compiler doesn't like

modified   ntoskrnl/ke/i386/usercall.c
   Dispatch the correct EXCEPTION_RECORD in case of exception inside KiInitializeUserApc

modified   ntoskrnl/ke/powerpc/exp.c
   Removed bogus, unused SEH code

modified   ntoskrnl/ntoskrnl-generic.rbuild
   Sources using PSEH 2.0 must be compiled with -fno-unit-at-a-time due to a GCC bug. See also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17982 and http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38054
   Apparently, -fno-unit-at-a-time makes GCC crash when using precompiled headers. Disable precompiled headers for ntoskrnl
