eff8154913 USB HID descriptors may push/pop the current state to allow
description of items residing in a so-called union. FreeBSD currently
only supports 4 such pop levels.

If the push level is not restored within the processing of the same
HID item, an invalid memory location may be used for subsequent HID
item processing.

Verify that the push level is always valid when processing HID items.

5e53a4f90f lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

ec9b9fbd50 Restore handling of the third argument (id) of hid_start_parse(), same as
it is done in NetBSD/OpenBSD, and as it was here before r205728.

I personally think this API or its implementation is incorrect, as it is not
correct to filter collections based on report ID, as they are orthogonal
in general case, but I see no harm from supporting this feature.

cff79d9ed3 HID Report ID is unsigned value, so clear the rest of bits from possible
sign expansion.

7778ab7e0c MFprojects/hid:
Import the rest of HID improvements from the branch:
 - improve report descriptor parser in libusbhid to handle several kinds of
reports same time;
 - add to the libusbhid API two functions wrapping respective kernel IOCTLs
for reading and writing reports;
 - tune uhid IOCTL interface to allow reading and writing arbitrary report,
when multiple supported by the device;
 - teach usbhidctl to set output and feature reports;
 - make usbhidaction support all the same item names as bhidctl.

1bee2ec756 MFprojects/hid:
- Fix usbhidctl and usbhidaction to handle HID devices with multiple
report ids, such as multimedia keyboards.
 - Add collection type and report id to the `usbhidctl -r` output. They
are important for proper device understanding and debugging.
 - Fix usbhidaction tool to properly handle items having report_count
more then 1.

cde587816c Merge improvements from kernel HID parser to the userland usbhid(3)
parser.  This merge does not change any API and should not break any
native or thirdparty applications.

Changes include:

* Merge multiple report ID support and other improvements from kernel
  HID parser.
* Ignore rid argument in hid_start_parser, parse all the report items since
  we now support multiple report ID.
* Skip report ID byte in hid_get_data() and set report ID byte in
  hid_set_data(), if report ID is non-zero.
* Reimplement hid_get_report_id: instead get report id from uhid device
  (which is always 0), try parsing the report descriptor and return the
  first report ID encountered.

cf0e07e504 Sync with NetBSD.
- Bump shared library version on libusbhid.
- Retire libusbhid.h; it is called usbhid.h now.
- hid_start_parse() takes a third argument.
- hid_locate() takes a fifth argument.
- hid_report_size() order of arguments changes.
- Other changes, including formatting and whitespace.

Bump __FreeBSD_version.

This change will break all third party applications that rely on previous
FreeBSD specific behavior.
