in the case where the host has a large journald, iterating the journal
without using a Match is very poor performance. this might be a
temporary fix while we figure out why the systemd library does not seem to
behave properly.

JSON optimizes it out in that case anyways, so don't waste cycles
doing an Itoa (and Atoi on the decode side).

We weren't actually storing this, so we'd lose the exit code for
containers run with --rm or force-removed while running if the
journald backend for events was in use.

it looks like the core-os systemd library has some issue when using
seektail and add match. this patch works around that shortcoming for
the time being.

We need this specifically for tests, but others may find it
useful if they don't explicitly need events and don't want the
performance implications of using them.

an internal change in libpod will soon required the ability to lookup
the last container event using the continer name or id and the type of
event. this pr is in preperation for that need.

once the default event logger was removed from libpod.conf, we need to
set the default based on whether the systemd build tag is used or not.

If the systemd development files are not present on the system which
builds podman, then `podman events` will error on runtime creation.
Beside this, a warning will be printed when compiling podman.
This commit mainly exists because projects which depend on libpod
would not need the podman event support and therefore do not need to
rely on the systemd headers.

add the ability for podman to read and write events to journald instead
of just a logfile. This can be controlled in libpod.conf with the
`events_logger` attribute of `journald` or `file`. The default will be
set to `journald`.

We have a new event for container 'Exited' which has been renamed to
'died'.
also removed the stream bool from the varlink endpoint for events
because it can be determined by the varlink more value.

In lipod, we now log major events that occurr. These events
can be displayed using the `podman events` command. Each
event contains:
* Type (container, image, volume, pod...)
* Status (create, rm, stop, kill, ....)
* Timestamp in RFC3339Nano format
* Name (if applicable)
* Image (if applicable)
The format of the event and the varlink endpoint are to not
be considered stable until cockpit has done its enablement.
