d06d285e66 logFile until flag issue
we were adding a negative duration in podman events, causing inputs like
-5s to be correct and 5s to be incorrect.

37f39eefee events: support disjunctive filters
While different filters are applied in conjunction, the same filter (but
with different values) should be applied in disjunction.  This allows,
for instance, to query the events of two containers.

74fcd9fef3 podman events allow future time for --until
The podman events aren't read until the given timestamp if the
timestamp is in the future. It just reads all events until now
and exits afterwards.
This does not make sense and does not match docker. The correct
behavior is to read all events until the given time is reached.

This fixes a bug where the wrong event log file path was used
when running first time with a new storage location.
Fixes #8694

This also fixes the events api endpoint which only exited when
an error occurred. Otherwise it just hung after reading all events.

a3e0b7d117 add network connect|disconnect compat endpoints
this enables the ability to connect and disconnect a container from a
given network. it is only for the compatibility layer. some code had to
be refactored to avoid circular imports.

additionally, tests are being deferred temporarily due to some
incompatibility/bug in either docker-py or our stack.

d856e87f40 events endpoint: fix panic and race condition
Fix a potential panic in the events endpoint when parsing the filters
parameter.  Values of the filters map might be empty, so we need to
account for that instead of uncondtitionally accessing the first item.

Also apply a similar for race conditions as done in commit f4a2d25c0fca:

	Fix a race that could cause read errors to be masked.  Masking
	such errors is likely to report red herrings since users don't
	see that reading failed for some reasons but that a given event
	could not be found.

Another race was the handler closing event channel, which could lead to
two kinds of panics: double close, send to close channel.  The backend
takes care of that.  However, make sure that the backend stops working
in case the context has been cancelled.

9e4cf6ca51 Fix system service panic from early hangup in events
We weren't actually halting the goroutine that sent events, so it
would continue sending even when the channel closed (the most
notable cause being early hangup - e.g. Control-c on a curl
session). Use a context to cancel the events goroutine and stop
sending events.

bbfc80c579 performance fix for podman events with large journalds
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.

d1fc3fc702 Add systemd build tag
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.
