As part of a broader interface for all kernel datatypes that retain cached data, implement a drain method for caching heaps so that unused pages may be returned to parent heaps.

See #1130

Objcache: add locking option and drain functionality
dadc477 
This change introduces a new heap sub-type, called caching_heap,
that exports an additional callback to drain memory that has been
cached. The objcache heap is now a caching_heap.
In addition, the objcache heap now implements locking, which allows
safe use of the drain functionality in concurrently accessed heaps
without the need for an external lock.
Memory cleaner instances have been added in various places where an
objcache is used, so that caching heaps can be drained when the
system is low on memory.

Partially addresses #1494.
