Since the introduction of the whitelist in 60-persistent-storage.rules
block device symlinks are no longer created for scm block devices.
Add scm to the whitelist.

blkid reports PARTUUID values also for partitions that are defined by a
dos partitioning scheme. Instead of limiting the partitioning scheme to
"gpt or dos" just drop the test for the partitioning scheme and trust
blkid to do the right thing.
Currently, 99-systemd.rules.in contains a line for network block
devices, which mark them as inactive until the first change event, and
as active from then on forward. This is not correct. A network block
device can be connected or disconnected; this state is signalled by the
presence or absense of a "pid" file, which contains the PID of the
nbd client userspace process that started the connection.
Update the rules file so that it checks for the presence of that file to
decide what to set SYSTEMD_READY to.
Note that current kernels do issue a change event upon connecting the
device, but not yet upon disconnecting. While it's possible to wait
until that's been fixed, the behaviour of the rule with TEST!="pid" in
the absence of a proper uevent is exactly the same as the behaviour of
the old rule; so it should be safe to apply now.

The "SYSTEMD_READY=0" will cause automatic unmount
of mountpoint that is on top of such DM device
if this is used with multipath which sets
DM_UDEV_DISABLE_OTHER_RULES_FLAG in case
we have a CHANGE event thatcomes after DM multipath
device reload when one of the paths is down or up.

With this rework we introduce systemd-rfkill.service as singleton that
is activated via systemd-rfkill.socket that listens on /dev/rfkill. That
way, we get notified each time a new rfkill device shows up or changes
state, in which case we restore and save its current setting to disk.
This is nicer than the previous logic, as this means we save/restore
state even of rfkill devices that are around only intermittently, and
save/restore the state even if the system is shutdown abruptly instead
of cleanly.
This implements what I suggested in #1019 and obsoletes it.
The main purpose of this hwdb was to tag touchpads that have the physical
trackstick buttons wired to the touchpad (Lenovo Carbon X1 3rd, Lenovo *50
series). This hwdb is not required on kernels 4.0 and above, the kernel now
re-routes button presses through the trackstick's device node. Userspace does
not need to do anything.
See kernel commit cdd9dc195916ef5644cfac079094c3c1d1616e4c.
This reverts commit 001a247324.
It is not udev's task to apply any of these setting that way, or
from udev rules files. Things need to be sortet out in the kernel,
or explicit whitelist can possibly be added to the hardware database.
Until that is sorted out, and general agreement, udev is not
willing to maintain any such lists or power management settings
in general.
"Thanks for digging this out! I thought my Kinesis keyboard got broken
and ordered a new one, only to find out that the new one doesn't work
as well. I'm not sure whether we should start collecting a blacklist
of keyboards which don't work with USB autosuspend, or rather a
whitelist? Or revert this wholesale?"

USB and PCI soundcards have a nice set of ID_* properties. It would
be handy for firewire soundcards to have the same.
Note that this removes the explicit setting of ID_ID in the firewire
conditional. Because we are now setting ID_SERIAL, ID_ID will come
from later in the file.
The ALSA id sysattr is generated by the sound subsystem and is not
a stable identifier. It is generated though some string manipulation
then made unique if there is a conflict. This means that it is
enumeration-dependent and shouldn't be used for ID_ID.
If ID_ID is supposed to be system-unique, it is not already since
for firewire it is generated from the guid and there are broken
firewire devices that have duplicate guids across devices.
This is tracked for PulseAudio at
https://bugs.freedesktop.org/show_bug.cgi?id=90129.
This is essentially a revert of systemd
ed1b2d9fc7.
We only care about whether our direct parent is removable, not whether any
further points up the tree are - the kernel will take care of policy for
those itself. This enables autosuspend on devices where the root hub reports
that its removable state is unknown.
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.
