Sebastian Sumpf 3207b4eed0 USB: Performance improvements 
Added SKB bitmap allocator, use Nic::Packet_allocator in packet stream, use slab
allocators on top of back-end AVL allocator, split allocators in cached/uncached
for general purpose/DMA allocation, added patch to original code to distinguish
cached or uncached memory requests, take advantage of and implement TX bursts
(or SKB batching), call interrupt handlers until they return unhandled.
