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

Rearrange the tunables and belonging sysctl declarations, so
that they are next to eachother.

Also update the port reset time from 250ms to 50ms. Some USB devices
have a hard limit in hardware at 222ms for the port reset time and will
not enumerate unless this delay is closer to the usb.org defined value.
This patch can fix enumeration with some USB devices.

in SUPER-speed mode, USB 3.0.
This feature has not been tested yet, due to lack of hardware.
This feature is useful when implementing protocols like UASP,
USB attached SCSI which promises higher USB mass storage throughput.
This patch also implements support for hardware processing of endpoints
for increased performance. The switching to hardware processing
of an endpoint is done via a callback to the USB controller driver. The
stream feature is implemented like a variant of a hardware USB protocol.
USB controller drivers implementing device mode needs to be updated to
implement the new "xfer_stall" USB controller method and remove the
"xfer" argument from the "set_stall" method.
The API's toward existing USB drivers are preserved. To setup a USB transfer
in stream mode, set the "stream_id" field of the USB config structure to
the desired value.
The maximum number of BULK streams is currently hardcoded and limited to 8
via a define in usb_freebsd.h.
All USB drivers should be re-compiled after this change.
LibUSB will be updated next week to support streams mode. A new IOCTL to
setup BULK streams as already been implemented. The ugen device nodes
currently only supports stream ID zero.
The FreeBSD version has been bumped.

- Reduce the number of headers needed for a usb driver, the common case is just usb.h and usbdi.h

usb_pipe may be used for a different purpose later on.

- Move tunable defines into usb_core.h and dependancy towards usb_defs.h
- Leave hardcoded defines in "usb_defs.h".
- Allow overriding all tunable defines.
- Add more customisable typedefs.
- Correct maximum device number.
