Modules: USB generic driver

This is my naive attempt at adding ALSA device support. The attached
patch provides support for the EDIROL UM-3ex. This is a 3-port USB midi
interface with a built-in USB hub and the ability to chain 2 other
UM-3x's in a master-slave configuration. I only have one, so I do not
know how this works in practice.

Though this is a 3-port device, I had to throw in that 4th 'Control' interface
to the definition in order to make the 3rd port work. If I set in/out_cables
to 0x000b, a 3rd interface appears on the driver, but it does nothing.
Changing it to 0x000f allows the 3rd interface to work, but of course
interface 4 does not work because it does not exist.

Simplify the handling of MIDI quirks by treating an interface without
quirks as a QUIRK_MIDI_STANDARD_INTERFACE.

This also fixes the bug where a MIDI_STANDARD quirk would not be
recognized.

When a USB error occurs that might indicate that the device has been
unplugged, don't resubmit the URB immediately to prevent flooding the
log with error messages before khubd has us disconnect()ed.

Emagic devices pad their packets not with 0xff bytes but with a 0xff

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
