rules: Limit USB autosuspend on USB HID devices
Some USB ports on external hubs may be reported as "fixed". We only want
to auto-enable this on ports that are internal to the machine, so check
the parent state as well.

scsi_id: fix truncated model in by-id device links
Do not forget the leading "S" when appending the serial number,
otherwise we chop the last character of the model name.

main: add configuration option to alter capability bounding set for PID 1
This also ensures that caps dropped from the bounding set are also
dropped from the inheritable set, to be extra-secure. Usually that should
change very little though as the inheritable set is empty for all our uses
anyway.
service: for Type=idle units consider START_PRE, START, START_POST all as ACTIVE
We want to avoid a deadlock when a service has ExecStartPre= programs
that wait for the job queue to run empty because of Type=idle, but which
themselves keep the queue non-empty because START_PRE was considered
ACTIVATING and hence the job not complete. With this patch we alter the
state translation table so that it is impossible ever to wait for
Type=idle unit, hence removing the deadlock.
Previously generated units were always placed at the end of the search
path. With this change there will be three unit dirs instead of one, to
place generated entries at the beginning, in the middle and at the end
of the search path:
beginning: for units that need to override all configuration, regardless
of user or vendor. Example use: system-update-generator uses this to
temporarily redirect default.target.
middle: for units that need to override vendor configuration, but not
vendor configuration. Example use: /etc/fstab should override vendor
supplied configuration (think /tmp), but should not override native user
configuration.
end: does not override anything but is available as well. Possible usage
might be to convert D-Bus bus service files to native units but allowing
vendor supplied native units to win.
units: remove service sysv_path variable and replace it by generic unit_path
UnitPath= is also writable via native units and may be used by generators
to clarify from which file a unit is generated. This patch also hooks up
the cryptsetup and fstab generators to set UnitPath= accordingly.
In rescue mode let's not establish all sockets, so that we don't end up
starting a lot of additional services automatically.
Instead of pulling in basic.target we now only pull in sysinit.target
which pulls in local-fs.target and swap.target. That way rescue mode has
all the really basic setup around, but normal services are not started
and not autostarted either.

service: fix auto-restart handling in service_stop()
When service_stop() handles a service in the SERVICE_AUTO_RESTART state,
it calls service_set_state() to transition it to the SERVICE_DEAD state.
However if the service failed, it should transition it to SERVICE_FAILED
instead, which will trigger its OnFailure units. To achieve this, we now
call service_enter_dead() in place of service_set_state(), which will
transition the service to either SERVICE_DEAD or SERVICE_FAILED as is
appropriate.
Also, some misleading comments are adjusted: service_stop() is not only
called on a user request, but also during an automatic restart in order
to handle dependencies.

Fixed handling of posix_fallocate() returned value
According to the man pages of posix_fallocate, it returns zero on
success or an error number on failure; however, errno is not set
on failure. If the kernel or a library other than glibc does not
support the function for example, EOPNOTSUPP will be returned and
the error will not be handled properly with original code.
Checking the device major/minor is not a good idea. Let's replace this
with an explicit flag file, which we model after /etc/os-release and
call /etc/initrd-release.

sd-pam: Drop uid so parent signal arrives at child.
The PAM helper thread needs to capture the death signal from the
parent, but is prohibited from doing so since when the child dies
as normal user, the kernel won't allow it to send a TERM to the
PAM helper thread which is running as root.
This causes the PAM threads to never exit, accumulating after
user sessions exit.
There is however really no need to keep the PAM threads running as
root, so, we can just setresuid() to the same user as defined in the
unit file for the parent thread (User=). This makes the TERM signal
arrive as normal. In case setresuid() fails, we ignore the error, so
we at least fall back to the current behaviour.
units: introduce new Documentation= field and make use of it everywhere
This should help making the boot process a bit easier to explore and
understand for the administrator. The simple idea is that "systemctl
status" now shows a link to documentation alongside the other status and
decriptionary information of a service.
This patch adds the necessary fields to all our shipped units if we have
proper documentation for them.

dbus-unit: always load the unit before handling a message for it
We need to be able to show the properties even of inactive units.
systemctl loads the unit before getting its properties, but this is racy
as the garbage collector may kick in right after the loading.
Fix it by always loading the unit before handling a message for it.
