4afd3348c7 tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easy
GLIB has recently started to officially support the gcc cleanup
attribute in its public API, hence let's do the same for our APIs.

With this patch we'll define an xyz_unrefp() call for each public
xyz_unref() call, to make it easy to use inside a
__attribute__((cleanup())) expression. Then, all code is ported over to
make use of this.

The new calls are also documented in the man pages, with examples how to
use them (well, I only added docs where the _unref() call itself already
had docs, and the examples, only cover sd_bus_unrefp() and
sd_event_unrefp()).

This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we
tend to call our destructors these days.

Note that this defines no public macro that wraps gcc's attribute and
makes it easier to use. While I think it's our duty in the library to
make our stuff easy to use, I figure it's not our duty to make gcc's own
features easy to use on its own. Most likely, client code which wants to
make use of this should define its own:

       #define _cleanup_(function) __attribute__((cleanup(function)))

Or similar, to make the gcc feature easier to use.

Making this logic public has the benefit that we can remove three header
files whose only purpose was to define these functions internally.

See #2008.

dc83f27a7c man: fully document sd-event interfaces
This completes the set of man pages for sd-event and contains some minor
other fixes for other man pages too.

The sd_event_set_name(3) man page is renamed to
sd_event_source_set_description(3), which is the correct name of the
concept today.

36b4a7ba55 Remove snapshot unit type
Snapshots were never useful or used for anything. Many systemd
developers that I spoke to at systemd.conf2015, didn't even know they
existed, so it is fairly safe to assume that this type can be deleted
without harm.

The fundamental problem with snapshots is that the state of the system
is dynamic, devices come and go, users log in and out, timers fire...
and restoring all units to some state from the past would "undo"
those changes, which isn't really possible.

Tested by creating a snapshot, running the new binary, and checking
that the transition did not cause errors, and the snapshot is gone,
and snapshots cannot be created anymore.

New systemctl says:
Unknown operation snapshot.
Old systemctl says:
Failed to create snapshot: Support for snapshots has been removed.

IgnoreOnSnaphost settings are warned about and ignored:
Support for option IgnoreOnSnapshot= has been removed and it is ignored

8dd4c05b54 core: add support for naming file descriptors passed using socket activation
This adds support for naming file descriptors passed using socket
activation. The names are passed in a new $LISTEN_FDNAMES= environment
variable, that matches the existign $LISTEN_FDS= one and contains a
colon-separated list of names.

This also adds support for naming fds submitted to the per-service fd
store using FDNAME= in the sd_notify() message.

This also adds a new FileDescriptorName= setting for socket unit files
to set the name for fds created by socket units.

This also adds a new call sd_listen_fds_with_names(), that is similar to
sd_listen_fds(), but also returns the names of the fds.

systemd-activate gained the new --fdname= switch to specify a name for
testing socket activation.

This is based on #1247 by Maciej Wereski.

Fixes #1247.

d35c1bb1f4 rfkill: rework and make it listen on /dev/rfkill
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.

4a9b1dd4ad machine-id-commit: merge machine-id-commit functionality into machine-id-setup
And remove machine-id-commit as separate binary.

There's really no point in keeping this separate, as the sources are
pretty much identical, and have pretty identical interfaces. Let's unify
this in one binary.

Given that machine-id-commit was a private binary of systemd (shipped in
/usr/lib/) removing the tool is not an API break.

While we are at it, improve the documentation of the command substantially.

dfb815c36d sd-bus: add sd_bus_path_{encode,decode}_many()

f5aaf57562 sd-login: add new sd_pid_get_cgroup() API
This adds a new sd_pid_get_cgroup() call to sd-login which may be used
to query the control path of a process. This is useful for programs when
making use of delegation units, in order to figure out which subtree has
been delegated.

In light of the unified control group hierarchy this is finally safe to
do, hence let's add a proper API for it, to make it easier to use this.

65d21ff344 build-sys: don't dist man/systemd.directives.xml
It depends on man/custom-entities.ent which is (and needs to be) a built file,
so we need to always build man/systemd.directives.xml as well.

We also need to drop this from update-man-list so that it doesn't get disted
from Makefile-man.am.

Fixes distcheck failure.

1b09f548c7 turn kdbus support into a runtime option
./configure --enable/disable-kdbus can be used to set the default
behavior regarding kdbus.

If no kdbus kernel support is available, dbus-dameon will be used.

With --enable-kdbus, the kernel command line option "kdbus=0" can
be used to disable kdbus.

With --disable-kdbus, the kernel command line option "kdbus=1" is
required to enable kdbus support.

06255d6f76 man: add libudev man-pages (skeletons)
This adds man-pages for most of the libudev symbols we export. Similar
symbols are grouped together in a single man-page, with respective links
added. All man-pages contain the full skeleton including NAME, SYNOPSIS,
RETURN VALUE and SEE ALSO. However, most of them still lack the
DESCRIPTION part. This should be copied from the gtkdoc descriptions in
src/libudev/libudev*.[ch]. Any help is welcome! (the whole skeleton is
already done, so it's really just about the prose-part of the man-pages to
be written).

Missing from the man-pages are the following parts:
  - udev_set_log_fn()
  - udev_[gs]et_log_priority()
  - udev_[gs]et_userdata()
  - udev_list_entry_foreach()
  - udev_device_get_seqnum()
  - udev_device_get_usec_since_initialized()
  - udev_util_encode_string()
These are considered legacy, afaik. If not, please feel free to add them
now!

Furthermore, udev-hwdb and udev-queue are not documented at all (for the
same reasons).

96d9117ad2 fsck: remove fsckd again, but keep the door open for external replacement
For a longer discussion see this:

http://lists.freedesktop.org/archives/systemd-devel/2015-April/030175.html

This introduces /run/systemd/fsck.progress as a simply
AF_UNIX/SOCK_STREAM socket. If it exists and is connectable we'll
connect fsck's -c switch with it. If external programs want to get
progress data they should hence listen on this socket and will get
all they need via that socket. To get information about the connecting
fsck client they should use SO_PEERCRED.

Unless /run/systemd/fsck.progress is around and connectable this change
reverts back to v219 behaviour where we'd forward fsck output to
/dev/console on our own.

a354329f72 core: add new logic for services to store file descriptors in PID 1
With this change it is possible to send file descriptors to PID 1, via
sd_pid_notify_with_fds() which PID 1 will store individually for each
service, and pass via the usual fd passing logic on next invocation.
This is useful for enable daemon reload schemes where daemons serialize
their state to /run, push their fds into PID 1 and terminate, restoring
their state on next start from the data in /run and passed in from PID
1.

The fds are kept by PID 1 as long as no POLLHUP or POLLERR is seen on
them, and the service they belong to are either not dead or failed, or
have a job queued.
