slab: implement bulk alloc in SLAB allocator

Browse source

This patch implements the alloc side of bulk API for the SLAB allocator.

Further optimization are still possible by changing the call to
__do_cache_alloc() into something that can return multiple objects.
This optimization is left for later, given end results already show in
the area of 80% speedup.
