Pointer acceleration for relative input devices (mice, trackballs, etc.)
applies to the deltas of the device. Alas, those deltas have no physical
reference point - a delta of 10 may be caused by a large movement of a
low-dpi mouse or by a minute movement of a high-dpi mouse.
Which makes pointer acceleration a bit useless and high-dpi devices
essentially unusable.
In an ideal world, we could read the DPI from the device directly and work
with that. In the world we actually live in, we need to compile this list
manually. This patch introduces the database, with the usual match formats
and a single property to be set on a device: MOUSE_DPI
That is either a single value for most mice, or a list of values for mice
that can change resolution at runtime. The exact format is detailed in the
hwdb file.
Note that we're explicitly overshooting the requirements we have for
libinput atm. Frequency could be detected in software and we don't
actually use the list of multiple resolutions (because we can't detect
when they change anyway). However, we might as well collect those values
from the get-go, adding/modifying what will eventually amount to hundreds
of entries is a bit cumbersome.
Note: we rely on the input_id builtin to tag us as mouse first, ordering
of the rules is important.

udev seems to have a race condition with swapon to see which can open
/dev/zram0 first, causing swapon to fail. Seems to be most noticeable
on arm devices one out of every 7 times or something.

This commit imports the new internal keyboard handling from upstream.
This is a combination of many upstream commits, including those
that added code, removed old code, and updated the hwdb.
Some commits (hwdb ones specifically) were unrelated but brought
in anyways to keep the whole hwdb consistent. Each upstream
commit included is as follows:

All code from each of the above commits is attributed to the original
authors.
There were some adjustments made in order to support the code differences
between upstream and eudev, which was done by myself.
Also of note is that the code can still be disabled via the --disable-keymaps
configure option, which was removed from upstream.

This sets the permissions on null, zero, full, random and urandom
to 666 which is needed for older kernels. This is part of Gentoo's
40-gentoo.rules which can now be dropped from Gentoo's ebuild.

Currently, keymaps are provided only for the NP90X3A laptop. Samsung
introduced updated models, codenamed 900X3B, 900X3C, 900X4B, 900X4C,
which are currently not matched by udev rules. This patch includes the
newer modules in udev rules and move the samsung-n90x3a file defining
keys to a more generic samsung-series-9 file.
The patch was tested on a 900X4C laptop, and other people reported
that the rules also work for 900X3B and 900X3C ones.
