USB_IAD: Adds support for USB Interface Association Descriptors.
This patch adds support to the USB host stack for parsing, storing, and
displaying Interface Association Descriptors. In /proc/bus/usb/devices
lines starting with A: show the fields in an IAD. In sysfs if an
interface on a USB device is referenced by an IAD the following files
will be added to the sysfs directory for that interface:
iad_bFirstInterface, iad_bInterfaceCount, iad_bFunctionClass, and
iad_bFunctionSubClass, iad_bFunctionProtocol

Many device manufacturers are using full-speed bInterval values in high-speed
interrupt endpoint descriptors. If the bInterval value is greater than 16,
assume the device uses full-speed descriptors and fix the value accordingly.

A noticeable number of low-speed devices mistakenly include
descriptors for Bulk endpoints, which is forbidden by the USB spec.
In an attempt to make such devices more usable, this patch (as924)
converts the descriptors to Interrupt with an interval of 1 ms.

This patch (as904) adds code to check for endpoint descriptor bInterval
values outside the legal limits. Illegal values are set to 32 ms, which
seems like a reasonable default.
This fixes Bugzilla #8432.

This patch (as907) prevents us from trying to allocate 0 bytes
when an interface has no endpoint descriptors.

Change usb_get_configuration() so that it is more tolerant to devices
with bad configuration descriptors (it'll make it ignore
configurations that fail to load).

This lets us remove a lot of code in the drivers that were all checking
the same thing. It also found some bugs in a few of the drivers, which
has been fixed up.

This patch (as592) makes a few small improvements to the way device
strings are handled, and it fixes some bugs in a couple of other sysfs
attribute routines. (Look at show_configuration_string() to see what I
mean.)

This patch (as590) fixes up all the remaining places where usbcore can
use kzalloc rather than kmalloc/memset.

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!
