Adrien Destugues 68d37cfb3a Fix definition of PAGESIZE and B_PAGE_SIZE
On sparc, the minimal page size we can use is 8K. Since B_PAGE_SIZE and
PAGESIZE defines were hardcoded to 4K, this resulted in a lot of
confusion in all code trying to manipulate pages.

- Remove cpu.h from headers/private/kernel/arch/*. It dates back from
  NewOS and was not used anymore since our kernel uses B_PAGE_SIZE
  (PAGE_SIZE was the only thing defined in this header).
- Add posix/arch/*/limits.h with the arch specific page size and include
  it from the main limits.h.
- Adjust bios_ia32/debug.cpp which was the only place using the
  PAGE_SIZE constant from the deleted headers.
- Change OS.h to define B_PAGE_SIZE to be the same as POSIX PAGESIZE.
- Define PAGESIZE in the build header if the host OS doesn't.
