b2fa7d8104 Change type of the DMA address so that on PAE platforms we get can 
64-bit DMA addresses even though the USB stack currently only uses
32-bit DMA.

d2b99310b1 Modify the FreeBSD USB kernel code so that it can be compiled directly 
into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.

Add new file containing the USB stack configuration for the
FreeBSD loader build.

Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.

Use cases:
 - console in loader via USB
 - loading kernel via USB

Discussed with:		Hiroki Sato, hrs @ EuroBSDCon

ed6d949afd - Make struct usb_xfer opaque so that drivers can not access the internals 
- Reduce the number of headers needed for a usb driver, the common case is just   usb.h and usbdi.h

f9cb546c23 Revert the size_t part of the last commit for the moment, this blows up the 
USB_ADD_BYTES macro.

3e8739762f Unifdef __NetBSD__ here, the usb stack as a whole doesnt support NetBSD and it 
obsfucates the code.
