A common use (e.g. in Ubuntu) for udevadm monitor is to log the events
received by udev during boot; events can be lost of the buffer size isn't
increased as udevd does.

This function is useful for anything that's likely to be running
alongside udevd during cold-plugging, and is using libudev to
receive the events.
It makes little sense for it to be private, or to require other
software to relearn how to adjust the buffer size.

Dell Studio 1557 does not generate a release code when the volume keys
are pressed, causing them to generate infinite key presses. This forces
key release of these keys.

The MSI Wind 100 generates ACPI/input events on the LNXVIDEO input device. On
top of that, the video module/BIOS synthesize some extra event on atkbd as an
echo of actually changing the brightness.
Ignore the wrong and useless atkbd ones, to avoid event loops.
Many thanks to Hans de Goede for tracking this down!

The new firmware loader does not report an error to the kernel if a firmware file
is missing. This results in modprobe stalling for 60 seconds for each firmware
a module tries to load.
Many statements in this document are no longer correct, or even
suggest things we do not want to support, or do not work at all
with the current version of udev.
Any new documentation should better be added to the udev man page,
which is usually kept up-to-date.
virtio ports spawned by the virtio_console.c driver can have 'names'
assigned to them by hosts. The ports are distinguishable using these
names. Make a rule to create a symlink to the chardev associated for a
port with a name.
The symlink created is:
/dev/virtio-ports/org.libvirt.console0 -> /dev/vport0p0
if the first port for the first device was given a name of
'org.libvirt.console0'.

Move extras/keymap/keymaps/force-release/ to
extras/keymap/force-release-maps/, so that check-keymaps.sh does not stumble
over the directory. It's also a more logical source layout.
We need to prevent that libudev parses half-written database files.
Also for "change" events, we need to make sure, that database files
always exist to be read by libudev, and that they are not first deleted
before they are re-created.
We do no longer delete the primary device node while handling "remove"
events if the same kernel device is already re-created in the meantime.
This prevents the asynchronously running udev from removing and re-creating
primary device nodes for active devices.
Commit d93fb59c50 ("rules: set mode of
floppy device nodes to 0660") changed the create_floppy_devices -M
argument to 0660, for udev-148.
Commit 78171d9549 reverted this, when it
moved the call to create_floppy_devices out to another rules file, for
udev-150.
Presumably the 0660 mode was correct, and the 0640 reversion was not
intentional; this restores 0660.

Add support for special function keys on Lenovo Thinkpad USB Keyboard
Tracepoint.
- VoIP hotkey "FN+F6" is mapped to camera, and may need to change
if there is a standard VoIP hotkey defined.
- Mute Microphone key has not been defined, as there is no
standard key defined for it yet.

The move_later_prefix variable was reset to zero on each
loop iteration, and thus the move_later entry (if any) was
not added right after changing to another syspath prefix,
but rather after exiting the enumeration loop.
