66b7a0f477 Renamed the _kern_init_heap_address_range() syscall to _kern_reserve_heap_address_range()
and made it more powerful.

79f73dbc56 * vm_page::offset is now called cache_offset and is now an uint32 instead of off_t;
this saves 4 bytes per page. To compensate the loss of bytes, the offset is now
  stored in page size units, that's enough to address 2^44 or 16 TB (which is now
  the maximal supported file size!).
* Renamed vm_page::ppn to physical_page_number.

d608540b67 Separated vm_address_space.h from vm.h.
Some more cleanup.

96e01a27bf * Merged vm_virtual_map with vm_address_space - there was no reason to have
them apart (this even saves a pointer from vm_virtual_map to its address space)
* aspace -> address_space
* vm_create_address_space() did not check if creating the semaphore succeeded
* Removed team::kaspace - was not really needed (introduced a new vm_kernel_address_space()
  function that doesn't grab a reference to the address space)
* Removed vm_address_space::name - it was just a copy of the team name, anyway,
  and there is always only one address space per team
* Removed aspace_id - the address space is now using the team_id
* Some cleanup.

51a3c450be The short story: we now have MTRR support on Intel and AMD CPUs (the latter
has not yet been tested, though - I'll do this after this commit):
* Removed the arch_memory_type stuff from vm_area; since there are only 8 memory
  ranges on x86, it's simply overkill. The MTRR code now remembers the area ID
  and finds the MTRR that way (it could also iterate over the existing MTRRs).
* Introduced some post_modules() init functions.
* If the other x86 CPUs out there don't differ a lot, MTRR functionality might
  be put back into the kernel.
* x86_write_msr() was broken, it wrote the 64 bit number with the 32 bit words
  switched - it took me some time (and lots of #GPs) to figure that one out.
* Removed the macro read_ebp() and introduced a function x86_read_ebp()
  (it's not really a time critical call).
* Followed the Intel docs on how to change MTRRs (symmetrically on all CPUs
  with caches turned off).
* Asking for memory types will automatically change the requested length to
  a power of two - note that BeOS seems to behave in the same, although that's
  not really very clean.
* fixed MTRRs are ignored for now - we should make sure at least, though,
  that they are identical on all CPUs (or turn them off, even though I'd
  prefer the BIOS stuff to be uncacheable, which we don't enforce yet, though).

4393552b4d The heap is now located at 384 MB, and creates a reserved range that spans over the
following 1152 MB - that area only guarantees that the heap can grow this much before
the application need the memory for something else. And even then, the heap range
is reused from top-to-bottom, allowing for maximum heap usage. Of course, if the
memory after the heap range is not claimed yet, it can still be claimed by the heap,
too. Added new syscall to create the reserved range.
Fixed a bug in vm_delete_areas(): when it removed reserved areas, the area list
could get messed up.
Fixed a bug in resize_area(): resized areas could never be deleted (missing vm_put_area())!
resize_area() now supports reserved regions (but not perfectly yet, see ToDo items).

a3e9996e9d Added support for special reserved address ranges: they will be used
only if memory becomes tight, and then the range is used from end to
start.
This is useful to reserve heap address ranges.

a49a5623f1 Got rid of regions - we're now back in area-land.
Renamed vm_area::lock to vm_area::protection to be less confusing - wiring
is still called wiring, though (might be renamed to lock later, as that's
how BeOS calls it).

67a53f72af - the arch_vm_translation_map.c exported functions now have the arch_ prefix
- the above file now also exports a function to finally complete the kernel's
  address space translation map after semaphores became available (was just
  not done before)
- renamed some functions, especially the *_init2() functions are now called
  like *_init_post_area() to indicate they are called after the area functionality
  became available
- removed the _struct suffix from certain structures
- fixed some return types
- added prototype for vm_free_unused_boot_loader_range() to be called by
  arch code.

a2ff38d818 vm_page no longer keeps a pointer to the vm_cache_ref but to the vm_cache.
This cleans the page handling when having to make an area copy-on-write;
regions belong to vm_cache_ref, pages to vm_cache.
Added prototype for new call vm_copy_area().
Fixed some return types.

1a705b91b7 Removed team::_aspace_id since it already has a direct pointer to it.
Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.

f236d16605 Removed the vm_get_region_info() call and the vm_region_info structure -
they are now replaced by get_area_info() and the area_info structure.
get_area_info() still misses some pieces, though.
Added all missing VM user/kernel syscalls.
