Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

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.

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.

MF NetBSD:

- 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().

Finish the libusb.h -> libusbhid.h migration.
