Moved all pager page-mapping routines to memory.c
...
Added a new virtual address pool for contiguous virtual addresses for the pager.
This will help in mapping multi-page user buffers and files.

exchange_registers(), modified thread_control calls seem to work
...
- Fixed do_mmap() so that it returns mapped address, and various bugs.
- A child seems to fork with new setup, but with incorrect return value.
Need to use and test exregs() for fork + clone.
- Shmat searches an unmapped area if input arg is invalid, do_mmap()
should do this.
