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.

hid: Import functions and constants required by new subsystem
This does an import of quirk stubs, debugging macros from USB code and
numerous usage constants used by dependent drivers.
Besides, this change renames some functions to get a better matching
with userland library and NetBSD/OpenBSD HID code. Namely:
- Old hid_report_size() renamed to hid_report_size_max()
- New hid_report_size() calculates size of given report rather than
maximum size of all reports.
- hid_get_data_unsigned() renamed to hid_get_udata()
- hid_put_data_unsigned() renamed to hid_put_udata()
Compat shim functions are provided in usbhid.h to make possible compile
of legacy code unmodified after this change.
