[weiden] 13981: Alex Ionescu <[e-mail]>

Alex Ionescu <ionucu(a)videotron.ca>
- Reorganized Bootup code. Most of the Executive initialization is now
in ex/init.c
- Remove ExPostSystemEvent.
- Sped up Command-line parasing and wrote a function specificalyl for
it, to ease extensibility
- Sped up and optimized loading modules from FreeLoader. The data is
only looked up once and then the pointers are cached for easy re-use.
- Moved KeGetRecommendedSharedDataAlignmented to ke/main.c and
implemented it.
- Moved subsystem-specific intialization to their own subsystem, like Io
in ioinit and Cm in CmInit.
