The move to meson has made it so that all rendered/built files are now
nicely self-contained. This lets us greatly simplify our gitignore,
effectively just ignoring release tarballs and the few usual temporary
files we may deal with during development.

lxc-monitord instances are spawned on demand and, if this
happens from a service, the daemon is considered part of
it by systemd, as it is running in the same cgroups. This
can be avoided by leaving it running permanently.

- Merge dhclient-start and dhclient-stop into a single hook.
- Wait for a lease before returning from the hook.
- Generate a logfile when LXC log level is either DEBUG or TRACE.
- Rely on namespace file descriptors for the stop hook.
- Use settings from /<sysconf>/lxc/dhclient.conf if available.
- Attempt to cleanup if dhclient fails to shutdown properly.

Add new hooks leveraging dhclient from the host to automatically
configure the container interfaces. This is especially useful for
application containers which rely on an IPAM driver for network
configuration (e.g. Docker).

Add a test to see if we can start daemonized containers that have a very
short-lived init process. The point of this is to see whether we can correctly
retrieve the state.

lxc-ls nowadays is a C binary so there's no need to keep the python and
shell versions around anymore, remove them from the branch and cleanup
documentation and Makefiles.

I have no idea what this file is, but the build system seems to be
generating it, so let's ignore it.

Somehow our `make tags` target generates TAGS and not tags, so let's ignore
that too.

- move action() from common to sysvinit wrapper since its only really
applicable for sysvinit and not the other init systems
- fix bug in action() fallback, need to shift away msg before executing action
- make lxc-net 98 so it starts before lxc-container (99), otherwise the lxcbr0
won't be available when containers are autostarted
- make the default RUNTIME_PATH be /var/run instead of /run. On older
distros (like ol6.5) /run doesn't exist. lxc-net will create this directory
and attempt to create the dnsmasq.pid file in it, but this will fail when
SELinux is enabled because the directory will have the default_t type.
Newer systems have /var/run symlinked to /run so you get to the same place
in that case.
- add %postun to remove lxc-dnsmasq user when pkgs are removed
- fix bug in lxc-oracle template that was creating /var/lock/subsys/lxc as
a dir and interfering with the init scripts

This patch adds support for checkpointing and restoring containers via CRIU.
It adds two api calls, ->checkpoint and ->restore, which are wrappers around
the CRIU CLI. CRIU has an RPC API, but reasons for preferring exec() are
discussed in [1].
To checkpoint, users specify a directory to dump the container metadata (CRIU
dump files, plus some additional information about veth pairs and which
bridges they are attached to) into this directory. On restore, this
information is read out of the directory, a CRIU command line is constructed,
and CRIU is exec()d. CRIU uses the lxc-restore-net callback (which in turn
inspects the image directory with the NIC data) to properly restore the
network.
This will only work with the current git master of CRIU; anything as of
a152c843 should work. There is a known bug where containers which have been
restored cannot be checkpointed [2].

v2: fixed some problems with the s/int/bool return code form api function
v3: added a testcase, fixed up the man page synopsis
v4: fix a small typo in lxc-test-checkpoint-restore

This is the equivalent of the upstart lxc-net.conf to set up the LXC bridge.
This also drops "lxc.service" from tarballs. It is built source which depends
on configure options, so the statically shipped file will not work on most
systems.
