Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.

We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.

Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)

Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.

Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.

mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.
Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.

Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.

Add couple of assertions CPU != NULL.
Change type of nrdy from int to count_t.
Rewrite halt() to avoid page fault when CPU == NULL.

Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().

Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.
Cleanup.

1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option

Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.
Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code.

Switch over to per vm_t page tables. (breaks ia32 userspace)
Define dummy memcopy() for amd64 and ppc to satisfy compiler.
Get rid of problematic #include <arch/mm/page.h> in mm/page.h.
Indentation fixes and small changes here and there.
