9dae5ee490 USB: Use real HID driver in dde_linux
Before, usb_drv included both the real HID driver and also Linux's early
boot USB driver (BP). The BP drivers have been removed now.

Fixes #440.

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.

9f73476b37 New DDE-Linux-based USB driver
The new 'dde_linux' repository will host device drivers ported from the
Linux kernel. In contrast to the original 'linux_drivers' repository,
'dde_linux' does not contain any 3rd-party source code. To download the
Linux kernel source code and extract the drivers, execute the 'make
prepare' rule of the top-level Makefile. The initial version of the
'dde_linux' repository comes with an USB driver. The porting methodology
follows the path of the Intel GEM port. Instead of attempting to provide
a generic Linux environment that works across drivers, each driver comes
with a specially tailored DDE.

The DDE consists of Genode-specific implementations of Linux API
functions as declared in 'lx_emul.h'. Most of these functions are
dummies that must merely be provided to resolve dependencies at the
linking stage. They are called by unused code-paths.

As of now, the USB driver support UHCI, EHCI on the x86_32 platform. I
exposes USB HID devices and USB storage devices via Genode's input-session
and block-session respectively.

The USB driver is accompanied with two run scripts 'run/usb_hid.run' and
'run/usb_storage.run'.
