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.

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.

- 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.

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.

- 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.
- Reduce diffs with NetBSD.
- Formatting and explicit values for enum declaration.
- Order of prototypes.
- zero report_size in hid_clear_local()
- errx() needs no newline
- Don't initialie variable in declaration in hid_parse_usage_in_page().
- Use fmtcheck() in hid_usage_in_page().
K&R -> ANSI
Bugfix: 'Keep the bit position even when the report descriptor says POP.'
Add hid_use_report_desc, hid_parse_usage_page, hid_parse_usage_in_page.
Changed iface for hid_report_size.
