a202ed6115 Use a newtype usec_t for timestamps for better type-safety 
This avoids mixing up milliseconds and usec, both by failing if
we're providing just a number somewhere we expect usecs and also
by making the API blindingly obvious that we're in usecs now.

428a3299a8 plugin: don't initialize the debounce plugin on a virtual device 
Effectively the same motivation as commit 5d23794d53 ("tablet: disable
smoothing for uinput devices") - virtual devices should not need
debouncing and if they do let's do the debouncing on the other end that
creates those devices.

4d317eae17 plugin: reset the filtered frame after sending it with buttons 
Our filtered frame (frame without any button events) that gets passed
down to here may include relative motion or other events. Once we use
that frame to prepend the button event we need to reset it so we don't
cause duplicate motion and/or events with zero delta timestamps.

With the the previous code we got two identical frames:

 event25  POINTER_MOTION            2  +0.360s	 -nan/  -nan ( -7.00/ -7.00)

The 0ms delta caused a -nan in the custom pointer accel but even without
that bug the pointer would've jumped more than it should.

Closes #1172

b2cd9c69a0 plugin: remove the event frame callbacks when disabling a plugin 
In all cases we remove the device's handling from the plugin so let's
remove the event frame callback for this device.

d1dbbb7328 plugin: register plugins for the plugin-specific usages 
The debounce, wheel/wheel-low-res, double-tool and eraser-button plugins can limit
themselves to a specific usage.

The mtdev plugin needs to pass each each event to mtdev and the proximity
timer plugin needs to get each event's timestamp so they cannot be
restricted.

The forced-tool could be restricted but effectively any event on the
devices it works on will have one of those usages set so there's no
point.
