arch_vm_aspace_swap().
* The x86 implementation does now maintain a bit mask per
vm_translation_map_arch_info indicating on which CPUs the address
space is active. This allows flush_tmap() to avoid ICI for user
address spaces when the team isn't currently running on any other CPU.
In this context ICI is relatively expensive, particularly since we map
most pages via vm_map_page() and therefore invoke flush_tmap() pretty
much for every single page.
This optimization speeds up a "hello world" compilation about 20% on
my machine (KDEBUG turned off, freshly booted), but interestingly it
has virtually no effect on the "-j2" haiku build time.

This allows drivers to lock the memory outside of the original team context.
* create_area_etc() got a struct team as first argument, but that should have
been a team_id.
* Removed delete_area_etc() - there is already vm_delete_area() doing the same
thing.
* Renamed vm_get_address_space_by_id() to vm_get_address_space(), as there is
no other method of getting an address space.
* Removed erroneous white space.

to the private VM types are including vm_types.h now.
* Removed vm_page, vm_area, vm_cache, and vm_address_space typedefs; it's
cleaner this way, and the actual types are only used in C++ files now,
anyway.
* And that caused changes in many files...
* Made commpage.h self-containing.
* Minor cleanup.
