Vladimir Kondratyev	01f2e864f7	hid: Import usbhid - USB transport backend for HID subsystem. This change implements hid_if.m methods for HID-over-USB protocol [1]. Also, this change adds USBHID_ENABLED kernel option which changes device_probe() priority and adds/removes PnP records to prefer usbhid over ums, ukbd, wmt and other USB HID device drivers and vice-versa. The module is based on uhid(4) driver. It is disabled by default for now due to conflicts with existing USB HID drivers.

hid: Import usbhid - USB transport backend for HID subsystem.

This change implements hid_if.m methods for HID-over-USB protocol [1].

Also, this change adds USBHID_ENABLED kernel option which changes
device_probe() priority and adds/removes PnP records to prefer usbhid
over ums, ukbd, wmt and other USB HID device drivers and vice-versa.

The module is based on uhid(4) driver.  It is disabled by default for
now due to conflicts with existing USB HID drivers.

hid: Import hidbus(4)

This driver provides support for multiple HID driver attachments
to single HID transport backend. This ability existed in Net/OpenBSD
(uhidev and ihidev drivers) but has never been ported to FreeBSD.
Unlike Net/OpenBSD we do not use report number alone to distinct report
source but we follow MS way and use a top level collection (TLC) usage
index that report belongs to as a location key.

The driver performs child device autodiscovery based on HID report
descriptor data, proxying of HID requests from child devices to parent
transport backends and broadcasting of interrupts in backward direction.
