Merged branch haiku/branches/developer/bonefish/vm into trunk. This

introduces the following relevant changes:
* VMCache:
  - Renamed vm_cache to VMCache, merged it with vm_store and made it a
    C++ class with virtual methods (replacing the store operations).
    Turned the different store implementations into subclasses.
  - Introduced MergeStore() callback, changed semantics of Commit().
  - Changed locking and referencing semantics. A reference can only be
    acquired/released with the cache locked. An unreferenced cache is
    deleted and a mergeable cache merged when it is unlocked. This
    removes the "busy" state of a cache and simplifies the page fault
    code.
* Added VMAnonymousCache, which will implement swap support (work by
  Zhao Shuai). It is not integrated and used yet, though.
* Enabled the mutex/recursive lock holder asserts.
* Fixed DoublyLinkedList::Swap().
* Generalized the low memory handler to a low resource handler. And made
  semaphores and reserved memory handled resources. Made
  vm_try_resource_memory() optionally wait (with timeout), and used that
  feature to reserve memory for areas.
