ad1ad5c8e3 networkd: Introduce Link Layer Discovery Protocol (LLDP)
This patch introduces LLDP support to networkd. it implements the
receiver side of the protocol.

The Link Layer Discovery Protocol (LLDP) is an industry-standard,
vendor-neutral method to allow networked devices to advertise
capabilities, identity, and other information onto a LAN. The Layer 2
protocol, detailed in IEEE 802.1AB-2005.LLDP allows network devices
that operate at the lower layers of a protocol stack (such as
Layer 2 bridges and switches) to learn some of the capabilities
and characteristics of LAN devices available to higher
layer protocols.

72648326ea import: add new minimal tool "systemd-import" for pulling down foreign containers and install them locally
This adds a simply but powerful tool for downloading container images
from the most popular container solution used today. Use it like
this:

       # systemd-import pull-dck mattdm/fedora
       # systemd-nspawn -M fedora

This will donwload the layers for "mattdm/fedora", and make them
available locally as /var/lib/container/fedora.

The tool is pretty complete, as long as it's only about pulling down
images, or updating them. Pushing or searching is not supported yet.

c853953658 load-fragment: allow quoting in command name and document allowed escapes
The handling of the command name and other arguments is unified. This
simplifies things and should make them more predictable for users.
Incidentally, this makes ExecStart handling match the .desktop file
specification, apart for the requirment for an absolute path.

ba774317ac Treat a trailing backslash as an error
Commit a2a5291b3f changed the parser to reject unfinished quoted
strings. Unfortunately it introduced an error where a trailing
backslash would case an infinite loop. Of course this must fixed, but
the question is what to to instead. Allowing trailing backslashes and
treating them as normal characters would be one option, but this seems
suboptimal. First, there would be inconsistency between handling of
quoting and of backslashes. Second, a trailing backslash is most
likely an error, at it seems better to point it out to the user than
to try to continue.

Updated rules:
ExecStart=/bin/echo \\ → OK, prints a backslash
ExecStart=/bin/echo \ → error
ExecStart=/bin/echo "x → error
ExecStart=/bin/echo "x"y → error

e40872fc53 path-util: fix breakage in path_is_mount_point
This fixes 2 problems introduced by 6feeeab0bc:

1) If name_to_handle_at returns ENOSYS for the child, we'll wrongly
return -ENOSYS when it returns the same for the parent. Immediately
jump to the fallback logic when we get ENOSYS.

2) If name_to_handle_at returns EOPNOTSUPP for the child but suceeds
for the parent, we'll be comparing an uninitialized value (mount_id) to
an initialized value (mount_id_parent). Initialize the mount_id
variables to invalid mount_ids to avoid this.

7943f42275 journal: optimize iteration by returning previously found candidate entry
In next_beyond_location() when the JournalFile's location type is
LOCATION_SEEK, it means there's nothing to do, because we already have
the location of the candidate entry. Do an early return. Note that now
next_beyond_location() does not anymore guarantee on return that the
entry is mapped, but previous patches made sure the caller does not
care.

This optimization is at least as good as "journal: optimize iteration:
skip files that cannot improve current candidate entry" was.

Timing results on my workstation, using:
$ time ./journalctl -q --since=2014-06-01 --until=2014-07-01 > /dev/null

Before "Revert "journal: optimize iteration: skip files that cannot
improve current candidate entry":

real    0m5.349s
user    0m5.166s
sys     0m0.181s

Now:

real    0m3.901s
user    0m3.724s
sys     0m0.176s

6e693b42dc journal: optimize iteration by skipping exhausted files
If from a previous iteration we know we are at the end of a journal
file, don't bother looking into the file again. This is complicated by
the fact that the EOF does not have to be permanent (think of
"journalctl -f"). So we also check if the number of entries in the
journal file changed.

This optimization has a similar effect as "journal: optimize iteration:
skip whole files behind current location" had.

1eb6332d55 journal: simplify set_location()
set_location() is called from real_journal_next() when a winning entry
has been picked from among the candidates in journal files.

The location type is always set to LOCATION_DISCRETE. No need to pass
it as a parameter.
The per-JournalFile location information is already updated at this
point. No need for having the direction and offset here.

6573ef05a3 journal: keep per-JournalFile location info during iteration
In next_beyond_location() when we find a candidate entry in a journal
file, save its location information in struct JournalFile.

The purpose of remembering the locations of candidate entries is to be
able to save work in the next iteration. This patch does only the
remembering part.

LOCATION_SEEK means the location identifies a candidate entry.
When a winner is picked from among candidates, it becomes
LOCATION_DISCRETE.
LOCATION_TAIL here signifies we've iterated the file to the end (or the
beginning in the case of reversed direction).

ee05e7795b core: use raw_clone instead of fork in signal handler
fork() is not async-signal-safe and calling it from the signal handler
could result in a deadlock when at_fork() handlers are called. Using
the raw clone() syscall sidesteps that problem.

The tricky part is that raise() does not work, since getpid() does not
work. Add raw_getpid() to get the real pid, and use kill() instead of
raise().

20b63d12b5 util: in make_stdio() use dup2() rather than dup3()
dup3() allows setting O_CLOEXEC which we are not interested in. However,
it also fails if called with the same fd as input and output, which is
something we don't want. Hence use dup2().

Also, we need to explicitly turn off O_CLOEXEC for the fds, in case the
input fd was O_CLOEXEC and < 3.
