9ce66e088e Add USB Audio 1.0 support 
Original commit credit to Amaury Pouly, Moshe Piekarski
Pushed across the finish line by Dana Conrad

To enable, see setting under General Settings --> System --> USB-DAC.
On devices with few endpoints, this may not work while HID and/or
mass storage is enabled.

Adds new dedicated mixer channel.

setting usb-dac can have values:
- never (0)
- always (1)
- while_charge_only (2)
- while_mass_storage (3)

Relevant devices are DWC2 and ARC usb controller devices. That being:
x1000 Native targets (m3k, erosqnative, q1, others...?),
sansac200, creativezenxfi2, vibe500, ipodmini2g,
ipod4g, creativezenxfi, creativezenxfi3, sansaview, ipodcolor,
creativezenxfistyle, samsungypz5, sansafuzeplus, iriverh10_5gb,

USB Driver-wise, it should be noted that this patch requires some
slight changes:
- proper blocking on control OUT transfers, to make sure the data is
  received *before* using it, the usb_core should probably use that too
- drivers can now support interface alternate settings
- drivers can be notified of completion by a new fast handler, which
  is called directly from the driver; this is is necessary for
  isochronous transfers because going through the usb queue is way too
  slow

Designware changes:

- enable for USBOTG_DESIGNWARE
- set maxpacketsize to 1023 for ISO endpoints

f3f9d1fb95 USB Serial: Implement Abstract Control Management 
On devices that can assign interrupt IN, bulk IN and bulk OUT endpoints
this change results in the serial interface working out of the box on
Linux and Windows. On Linux it is registered as ttyACM device and on
Windows it is assigned a COM port number.

On devices that cannot assign the interrupt IN this change won't have
any effect.

Implement minimum required interface control requests. Respond with
whatever line coding was set to make terminal programs happy.

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.

8181a0c905 Usb Stack: only setup packet handling, and not enabled by default as there is a lot to do. 
* settings code is not fully ready -> changing device driver has no effect
* clean ups
* check copyriths
* find a way to detect IN transfers
* support for full and highspeed
* ...
