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.

Can be disabled at runtime by setting hold switch.
Boosts sysbench sequential write performance by 34-58%

* DMA Bulk IN (ie our TX) results in sequential transfers 33-68% faster.
* DMA Bulk OUT (ie RX) is mostly stripped out due to complete brokenness.
* Interrupt and control endpoints remain PIO-driven.
Other improvements:
1) Use consistent endpoint references (no magic numbers)
2) Greatly enhanced logging
3) DMA support can be compiled out completely
4) Setting lockswitch will disable all DMA operations at runtime
5) Much more robust error checking and recovery
