MFC r360624:

[evdev] Add AT translated set1 scancodes for F-unlocked F1-12 keys.

"F lock" is a switch between two sets of scancodes for function keys F1-F12
found on some Logitech and Microsoft PS/2 keyboards [1]. When "F lock" is
pressed, then F1-F12 act as function keys and produce usual keyscans for
these keys. When "F lock" is depressed, F1-F12 produced the same keyscans
but prefixed with E0.
Some laptops use [2] E0-prefixed F1-F12 scancodes for non-standard keys.

sysmouse(4): Fix ums(4)-style T-axis reporting via evdev protocol

- Do not report T-axis wheel events as button presses
- Reverse T-axis to match Linux
- Remove wrong comment. T-axis buttons state should be checked by level not
by edge to allow continuous wheel tilt reporting

MFC r325298:

evdev: Disable value normalization and state filtering for SND events.

Some events can take sound pitch as a value so can not be represented
as binary on/off events. Tracking for on/off state is left in place
as it is a part of the evdev API.

[evdev] Fix build for older versions of clang

There was report of stable/11 build failure on older versions of
FreeBSD. The problem was a reference to static variable in inline
function. Although fairly recent versions of clang can cope with this
situation just fine there is no strict requirement to make functions
in question inline, they're not in any time-critical codepath. So to
keep HEAD and 11-STABLE buildable on older FreeBSDs some of the util
functions were converted from inline to normal.
