USB,USB USX2Y
Implements 'rawusb' pcm data transfer through hwdep interface:
The usb_hc moves pcm data from/into memory via DMA.
That memory is mmaped by jack's usx2y driver.
Jack's usx2y driver is the first/last executable code to read/write pcm data.
Read/write is a combination of power of 2 period shaping and float/int
conversation.

Compared to standard alsa/jack we leave out power of 2 period shaping
inside snd-usb-usx2y which needs memcpy() and additional buffers.
As a side effect possible unwanted pcm-data coruption resulting of
standard alsa's snd-usb-usx2y period shaping scheme falls away.
Result is sane jack operation at buffering schemes down to 128frames,
2 periods.

Also changed Kconfig file, so snd-usb-usx2y is only available for X86,
PPC or ALPHA platforms, as on others DMA-memory isn't mmapable.

In future kernels struct usb_device won't have the epmaxpacketin/out members.
Use macro usb_maxpacket() instead of directly accessing those members.

Yet another step in the quest to get all USB data structures to be native
endian.

These fields are in the struct usb_device_descriptor, and now we keep the 
native (on-the-wire mode) format of these fields.  Any driver using these
fields needs to convert it to cpu endian before using them.

All USB drivers in the kernel tree have been fixed up to work properly with
this change.  All out-of-the USB kernel drivers are on their own...

Version: 0.8.6
Work on this started, when rumors spread that OHCI equipped machines would
crash. This was due to me missing two facts:
1) Ohci has a bigger usb frame number wrap around.
2) It only supports URB_ISO_ASAP when submitting iso urbs.
These issues are fixed now.

Sigh...
	a) mixing of userland and kernel pointers is bad
	b) so's not checking result of kmalloc()
	c) so's not checking result of copy_from_user()
	d) use of do { .... break; ... break; ... } while(0); is *highly*
unidiomatic.  Do not confuse kernel with IOCCC, please. And if you have
religious aversion to multiple return statements in a function, at least
learn the reasons why it is frowned upon in many situations.  Hint: they
all apply to use of break in that manner.
	e) 0 instead of NULL

Added snd-usb-usx2y driver for Tascam US-122/224/428 support.
Driver written by Karsten Wiese <annabellesgarden@yahoo.de>

The shared code is split from usbaudio as snd-usb-lib module.
Currently, only MIDI part is included there.  In future, more
audio part will be shared, too.
