First step toward completely configurable CPU.
...
Change CPUID to generic interface which could be chosen from .bochsrc.
Bochs CPU emulation will enable/disable features (like instruction sets) according to CPUID that is selected.
TODO: Add database of CPUID from real hardware CPUs

reword all the CPU code in preparation for future CPU speedup implementation.
...
Bochs emulation can be another 10-15% faster using technique described in paper
"Fast Microcode Interpretation with Transactional Commit/Abort"

cleanup configure options. All paging related stuff is now automatically set/unset according to cpu-level option.
...
Related configure options (--enable-pae, --enable-mtrr, --enable-global-pages, --enable-large-pages) are deprecated.
Less configure options - less configure problems :)
