My YOGA requires a minimum of 7 to parse w/o an error. Since the memory savings
are trivial and the yoga a popular system, bump the default up to 8. There's no
API/ABI issues in doing this. This hid_item struct isn't exported to userland
and the one libusbhid has is different and only shares a name...

Many I2C "compatibility" mouse devices found on touchpads continue to
return last report data in sampling mode after touch has been ended.
That results in cursor drift. Filter out such a reports with comparing
content of current report with content of previous one.

There is a report that reading of surface/button switch feature report
causes SYN1B7D touchpad malfunction. As specs does not require it to
be readable assume that report usages have default value on attach and
last written value during operation. Do not apply default usage values
on attachment and resume.

This driver provides raw access to HID devices through uhid(4)-compatible
interface and is based on pre-8.x uhid(4) code. Unlike uhid(4) it does
not take devices in to monopoly ownership and allows parallel access
from other drivers.
hidraw supports Linux's hidraw-compatible interface as well.

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.

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.

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.
