interfaces, endpoints and generic descriptors.
* Add getter for active interface index and simplify the count operation as
it isn't misused to also get interface descriptors anymore.
* Refactor out some common code into helper functions.
* Adapt the USBKit to the changed/new interface.
* Change how alternate interfaces are exposed by USBKit by providing normal
BUSBInterface objects for alternate interfaces that can easily be examined
and used.
* Make BUSBInterface class aware of its alternate index and use the alternate
aware usb_raw functionallity to build the endpoint and descriptor lists.
* Add ActiveAlternateIndex() to find out what alternate is currently active.
* Style cleanup of the USBKit classes, use std::nothrow everywhere and check
all allocations. Simplify some code by removing optimization where the benefit
is questionable.

name, as it in fact is like a kit in the kit. It combines the different BUSB*
classes as compared to SerialPort.h where there really is a 1:1 relationship
between the header and the (one) class. If someone has a better fitting name
please shout.
Separated the usb_raw.h into usb_raw.h which defines the protocol and
usb_raw_private.h which holds the internal device structure for usb_raw. This
reduces the header dependencies.
Hopefully cought all occurencies of USBKit.a usage (in usb_dev_info and
the usb_webcam media add-on) but might have missed something that is not in
the image.
