cf0e07e504
- 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.
