9b3a48ee6f Add defines to more easily allow a single threaded version of the FreeBSD
USB stack. This is useful for non-kernel purposes, like the loader.

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

a5cf1aaaff Add support for the so-called streams feature of BULK endpoints
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.

d46dc4ad74 This patch adds automatic detection of USB mass storage devices
which does not support the no synchronize cache SCSI command.

The __FreeBSD_version version macro has been bumped and
external kernel modules needs to be recompiled after
this patch.

9eb0d7025d Improve enumeration of Low- and Full-speed devices connected through a
High-speed USB HUB by resetting the transaction translator (TT)
before trying re-enumeration. Also when clear-stall fails multiple times
try a re-enumeration.

d8d1becfdd Allow USB_HOST_ALIGN to be configured at compile time. This patch is
necessary for MIPS based RouterStation Pro board and maybe other MIPS
based boards as well.

b850ecc180 Change USB_DEBUG to #ifdef and allow it to be turned off. Previously this had
the illusion of a tunable setting but was always turned on regardless.

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
