This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.

MFC r305421: Resolve deadlock between device_detach() and usbd_do_request_flags() by reviving the SX control request lock and refining which lock protects the common scratch area in "struct usb_device".
The SX control request lock was removed by r246759 because it caused a lock order reversal with the USB enumeration lock inside usbd_transfer_setup() as a function of r246616. It was thought that reducing the number of locks would resolve the LOR, but because some USB device drivers use usbd_do_request_flags() inside callback functions, like in taskqueues, a deadlock may occur when these are drained from device_detach(). By restoring the SX control request lock usbd_do_request_flags() is allowed to complete its execution when a USB device driver is detaching. By using the SX control request lock to protect the scratch area, the LOR introduced by r246616 is also resolved.
Bump the FreeBSD version while at it to force recompilation of all USB kernel modules.

Implement better error recovery for Transaction Translators, TTs, found in High Speed USB HUBs which translate from High Speed USB into FULL or LOW speed USB. In some rare cases SPLIT transactions might get lost, which might leave the TT in an unknown state. Whenever we detect such an error try to issue either a clear TT buffer request, or if that is not possible reset the whole TT.

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

Make several timing parameters of the USB enumeration sequence tuneable. 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.

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.

This commit adds full support for USB 3.0 devices in host and device mode in the USB core. The patch mostly consists of updating the USB HUB code to support USB 3.0 HUBs. This patch also add some more USB controller methods to support more active-alike USB controllers like the XHCI which needs to be informed about various device state events.
USB 3.0 HUBs are not tested yet, due to lack of hardware, but are believed to work.
After this update the initial device descriptor is only read twice when we know that the bMaxPacketSize is too small for a single packet transfer of this descriptor.

If a USB device is suspended and a USB set config request is issued when the USB enumeration lock is locked, then the USB stack fails to resume the device because locking the USB enumeration lock is part of the resume procedure. To solve this issue a new lock is introduced which only protects the suspend and resume callbacks, which can be dropped inside the usbd_do_request_flags() function, to allow suspend and resume during so-called enumeration operations.

- make usb2_power_mask_t 16-bit - remove "usb2_config_sub" structure from "usb2_config". To compensate for this "usb2_config" has a new field called "usb_mode" which select for which mode the current xfer entry is active. Options are: a) Device mode only b) Host mode only (default-by-zero) c) Both modes. This change was scripted using the following sed script: "s/\.mh\././g". - the standard packet size table in "usb_transfer.c" is now a function, hence the code for the function uses less memory than the table itself.

This change is about removing three fields from "struct usb2_xfer" which can be reached from "struct usb2_xfer_root" instead and cleaning up the code after this change. The fields are "xfer->udev", "xfer->xfer_mtx" and "xfer->usb2_sc". In this process the following changes were also made: Rename "usb2_root" to "xroot" which is short for "xfer root". Rename "priv_mtx" to "xfer_mtx" in USB core. The USB_XFER_LOCK and USB_XFER_UNLOCK macros should only be used in the USB core due to dependency towards "xroot". Substitute macros for the real lock in two USB device drivers.

Bring in USB4BSD, Hans Petter Selasky rework of the USB stack that includes significant features and SMP safety.
This commit includes a more or less complete rewrite of the *BSD USB stack, including Host Controller and Device Controller drivers and updating all existing USB drivers to use the new USB API:
1) A brief feature list:
- A new and mutex enabled USB API.
- Many USB drivers are now running Giant free.
- Linux USB kernel compatibility layer.
- New UGEN backend and libusb library, finally solves the "driver unloading" problem. The new BSD licensed libusb20 library is fully compatible with libusb-0.1.12 from sourceforge.
- New "usbconfig" utility, for easy configuration of USB.
- Full support for Split transactions, which means you can use your full speed USB audio device on a high speed USB HUB.
- Full support for HS ISOC transactions, which makes writing drivers for various HS webcams possible, for example.
- Full support for USB on embedded platforms, mostly cache flushing and buffer invalidating stuff.
- Safer parsing of USB descriptors.
- Autodetect of annoying USB install disks.
- Support for USB device side mode, also called USB gadget mode, using the same API like the USB host side. In other words the new USB stack is symmetric with regard to host and device side.
- Support for USB transfers like I/O vectors, means more throughput and less interrupts.
- ... see the FreeBSD quarterly status reports under "USB project"
2) To enable the driver in the default kernel build:
2.a) Remove all existing USB device options from your kernel config file.
2.b) Add the following USB device options to your kernel configuration file:
# USB core support device usb2_core
# USB controller support device usb2_controller device usb2_controller_ehci device usb2_controller_ohci device usb2_controller_uhci
# USB mass storage support device usb2_storage device usb2_storage_mass
# USB ethernet support, requires miibus device usb2_ethernet device usb2_ethernet_aue device usb2_ethernet_axe device usb2_ethernet_cdce device usb2_ethernet_cue device usb2_ethernet_kue device usb2_ethernet_rue device usb2_ethernet_dav
# USB wireless LAN support device usb2_wlan device usb2_wlan_rum device usb2_wlan_ral device usb2_wlan_zyd
# USB serial device support device usb2_serial device usb2_serial_ark device usb2_serial_bsa device usb2_serial_bser device usb2_serial_chcom device usb2_serial_cycom device usb2_serial_foma device usb2_serial_ftdi device usb2_serial_gensa device usb2_serial_ipaq device usb2_serial_lpt device usb2_serial_mct device usb2_serial_modem device usb2_serial_moscom device usb2_serial_plcom device usb2_serial_visor device usb2_serial_vscom
# USB bluetooth support device usb2_bluetooth device usb2_bluetooth_ng
# USB input device support device usb2_input device usb2_input_hid device usb2_input_kbd device usb2_input_ms
# USB sound and MIDI device support device usb2_sound
2) To enable the driver at runtime:
2.a) Unload all existing USB modules. If USB is compiled into the kernel then you might have to build a new kernel.
2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same base name like the kernel device option.
