This is a leftover from when some of the filter code was shared between
pointer acceleration methods (pre v1.11 or so). Now these functions are
duplicated across files, so both the names and what they do isn't
necessarily reflective anymore.
Let's drop one layer of indirection to make the code a bit easier to
understand.
No functional changes.

libinput applies averaging to the velocity of most pointer devices. Averaging
the velocity makes the motion look smooth and may be of benefit to bad input
devices. For good devices, however, it comes at the unfortunate price of
decreased accuaracy.
This change turns velocity averaging off by default (sets ntrackers to 2 instead
of 16) and allows for it to be turned back on via a quirk, for bad devices which
require it.
Yeah, it's duplication. But this way it's also separation and we can't
accidentally use the wrong struct.

Plenty of duplication there from the normal filter.c, but that also makes it
less likely to break if we adjust the other one.
