udevadm manual says:
A value of 0 will check if the queue is empty and always return
immediately.
However, currently we ignore the deadline if the value is 0, and wait
without any limit.
Zero timeout behaved according to the documentation until commit
ead7c62ab7 (udevadm: settle - kill alarm()). Looking at this patch, it
seems that the behavior change was unintended.
This patch restores the documented behavior.

The Trust TB7300 (relabelled Waltop?) tablet has a scrollwheel which shows
up as a /dev/input/event# node all by itself. Currently input_id does not
set any ID_INPUT_FOO attr on this causing it it to not be recognized by
Xorg / libinput.
This commit fixes this by marking it with ID_INPUT_KEY.

IBM / Lenovo trackpoints allow specifying a sensitivity setting through a
ps/2 command, which changes the range of the deltas sent when using the
trackpoint.
On some models with normal usage only deltas of 1 or 2 are send, resulting in
there only being 2 mouse cursor movement speeds, rather than the expected fluid
scale. Changing the sensitivity to a higher level than the bootup default fixes
this.
This commit adds support for setting a POINTINGSTICK_SENSITIVITY value
in hwdb to allow changing the sensitivity on boot through udev / hwdb.

- No need to add "Error, " prefix, we already have that as metadata.
- Also use double quotes for path names, as in most other places.
- Remove stray newline at end of message.
- Downgrade error messages after which we continue to warnings.

udev uses inotify to implement a scheme where when the user closes
a writable device node, a change uevent is forcefully generated.
In the case of block devices, it actually requests a partition rescan.
This currently can't be synchronized with "udevadm settle", i.e. this
is not reliable in a script:
sfdisk --change-id /dev/sda 1 81
udevadm settle
mount /dev/sda1 /foo
The settle call doesn't synchronize there, so at the same time we try
to mount the device, udevd is busy removing the partition device nodes and
readding them again. The mount call often happens in that moment where the
partition node has been removed but not readded yet.
This exact issue was fixed long ago:
http://git.kernel.org/cgit/linux/hotplug/udev.git/commit/?id=bb38678e3ccc02bcd970ccde3d8166a40edf92d3
but that fix is no longer valid now that sequence numbers are no longer
used.
Fix this by forcing another mainloop iteration after handling inotify events
before unblocking settle. If the inotify event caused us to generate a
"change" event, we'll pick that up in the following loop iteration, before
we reach the end of the loop where we respond to settle's control message,
unblocking it.

Commit 9ea28c55a2 (udev: remove seqnum API and all assumptions about
seqnums) introduced a regresion, ignoring the timeout option when
waiting until the event queue is empty.
Previously, if the udev event queue was not empty when the timeout was
expired, udevadm settle was returning with exit code 1. To check if the
queue is empty, you could invoke udevadm settle with timeout=0. This
patch restores the previous behavior.
(David: fixed timeout==0 handling and dropped redundant assignment)

Parse properties in the form
EVDEV_ABS_00="<min>:<max>:<res>:<fuzz>:<flat>"
and apply them to the kernel device. Future processes that open that device
will see the updated EV_ABS range.
This is particularly useful for touchpads that don't provide a resolution in
the kernel driver but can be fixed up through hwdb entries (e.g. bcm5974).
All values in the property are optional, e.g. a string of "::45" is valid to
set the resolution to 45.
The order intentionally orders resolution before fuzz and flat despite it
being the last element in the absinfo struct. The use-case for setting
fuzz/flat is almost non-existent, resolution is probably the most common case
we'll need.
To avoid multiple hwdb invocations for the same device, replace the
hwdb "keyboard:" prefix with "evdev:" and drop the separate 60-keyboard.rules
file. The new 60-evdev.rules is called for all event nodes
anyway, we don't need a separate rules file and second callout to the hwdb
builtin.

No changes in the mapping, but previously we opened the device only on
successful parsing. Now we open the mapping as soon as we have a value that
looks interesting. Since errors are supposed to be the exception, not the
rule, this is probably fine.

Rather than building a map and looping through the map, immediately call the
ioctl when we have a successfully parsed property.
This has a side-effect: before the maximum number of ioctls was limited to the
size of the map (1024), now it is unlimited.

input_id already (tries to) tag accelerometers as such, but this only works
for absolute accelerometers. Recent kernels mark accelerometers through an
input prop. Trust that prop and always tag devices with it with
ID_INPUT_ACCELEROMETER.
Note that detection by the prop bit works the same as the existing detection
and will ensure that no other tags get set on the device.

Also referred to as trackpoint, trackstick. These are marked by recent kernels
through an input prop. Forward that prop as udev property so userspace can
easily determine whether there is a pointing stick present.
These devices were previously marked as ID_INPUT_MOUSE, for backwards
compatibility we keep that in place, the new property is an addition.y

We were explicitly eagerly loading the db, then deletenig the backing file and then processing the
rules/symlinks. Instead we delete the backnig db file as the last step and let the db loading be
lazy as everywhere else.
This may save us a bit of work in casese where the db is not needed, but more importantly it hides
some implementation details of libudev-device form udevd.

The call iterates through cmsg list and closes all fds passed via
SCM_RIGHTS.
This patch also ensures the call is used wherever appropriate, where we
might get spurious fds sent and we should better close them, then leave
them lying around.
