672bbe434b usb: rename usb_drv_recv() to usb_recv_recv_nonblocking() 
IMHO the current name is somewhat misleading:

- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
  for the non-blocking case. This inconsistent naming can only
  promote confusion. (And what would we call a blocking receive?)

- Other hardware abstraction APIs in Rockbox are usually blocking:
  storage, LCD, backlight, audio... in other words, blocking is the
  default expected behavior, with non-blocking calls being a rarity.

018372bf39 usb: implement macro for initializing USB strings 
This uses the new unicode string literal feature that is available
now to greatly simplify the initialization of these special string
types. This makes them much more readable at a quick glance.

91b850ec42 Get rid of usb_drv_attach() from USB code. 
'Twas an idiosyncrasy of detecting a host upon bus reset, which is
obsolete.

4fcffcbdf3 Reorganise USB initialisation to not depend on a specific enumeration sequence, by Bartosz Fabianowski, with minor tweaks by Michael Sevakis (FS#12497) 
FreeBSD apparently sends a SET_ADDRESS first, which confused our code.
This patch fixes that, and also simplifies the connection handling a bit.

69a4117c1d Add working USB HID driver, by Tomer Shalev (part of his GSoC work). 
This needs support for usb interrupt transfers, so there are some changes in various USB drivers as well (only usb-drv-arc supports it at this point, others won't have working HID yet).

HID is disabled for now, as the apps/ part is not included yet.

616c98b38f USB detection changes. c200/e200: Consider USB to be powered when charger is plugged but detect USB connection by bus reset. When received, disconnect and restart the driver fully enabled. imx31: Fix hack used to make initial connect succeeded-- set PHY type before initial reset. General: Move some target code out of usb-drv-arc.c and implement it in respective usb sources and CPU headers so things stay clean.

07427592a9 Major USB stack improvements. It now works at nearly the maximum speed for a full speed connection, and does seem stable. 
Still not enabled by default, #define USE_ROCKBOX_USB is still required to enable it.
