23128566a4 Slab.h no longer includes Depot.h.

b062823d81 * register_low_memory_handler() was called too early by several kernel 
components - now, we divide the initialization of that service into two parts
  which allows this (before, most handlers were gone after boot).
* Added debugger command that dumps the low memory handlers.
* The slab allocator now registers its low memory handler with a higher
  priority, so that it'll run before the potentially heavier ones.

5c4ed86b56 * Moved some definitions from vm_types.h that functions in vm.h need as 
arguments into vm.h.
* This should fix the broken build from earlier - thanks Stefano for the note!
* That also allowed to clean some other includes a bit.

e6dc7903e4 * vm.h no longer includes vm_types.h - only those that actually need access 
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.

8405223037 axeld+bonefish: Got rid of the ParentType in the HashTableDefinition; it doesn't really 
belong there.

8cfe0be38e slab/cache: a couple more fixes. 
- on CACHE_DURING_BOOT init benaphore count with 1.
 - account for allocated space on early_allocate_pages.
 - fixed slab position calculation in small slabs.
 - we can now init all allocator sizes early rather than later.

698b6d7195 cache/slab: when CACHE_DURING_BOOT is specified, use vm_allocate_early to obtain pages for slabs, and create the associated areas on post bootup.

11debaf6e4 added CACHE_UNLOCKED_PAGES flag to allow caches' pages to be created with no locking instead of full locking.

6bad493439 pushed the slab init a bit deeper. added a object cache based allocator, including a bootstrap mechanism to have it init during bootup.

6e31ae98f9 some object cache / slab improvements. 
- call the reclaimer callback when low on memory.
 - use the depot when on multi-cpu setups (for scalability).
 - fixed the amount of memory spent on slabs for very large objects.

5d6551d69f removed some of the slab's initial heavy debugging. we now merge the links into the slab itself resulting in zero overhead per buffer with MergedLink strategy.

e6fb3d3947 more slab fixes, also introduced a new strategy optimized for medium sized buffers (64 >= x < 512) with lengths other than power of 2 (has an overhead of 2 words per buffer).
