When checking if we have the development files for libsystemd's journal
APIs, check for either 'libsystemd >= 209' and 'libsystemd-journal'. If
we find 'libsystemd', define the 'journald' tag, which defaults to using
the 'libsystemd.pc' file. If we find the older 'libsystemd-journal',
define both the 'journald' and 'journald_compat' tags, which causes the
'libsystemd-journal.pc' file to be consulted instead.

inotify event is trigged immediately there's data written to disk.
But at the time that the inotify event is received, the json line might
not fully saved to disk. If the json decoder tries to decode in such
case, an io.UnexpectedEOF will be trigged.
We used to retry for several times to mitigate the io.UnexpectedEOF error.
But there are still flaky tests caused by the partial log entries.
The daemon knows exactly when there are new log entries emitted. We can
use the pubsub package to notify all the log readers instead of inotify.

this prevents the copier from sending messages in the buffer to the closed
driver. If the copied took longer than the timeout to drain the buffer, this
aborts the copier read loop and return back so we can cleanup resources
properly.

- Move time json marshaling to the jsonlog package: this is a docker
internal hack that we should not promote as a library.
- Move Timestamp encoding/decoding functions to the API types: This is
only used there. It could be a standalone library but I don't this
it's worth having a separated repo for this. It could introduce more
complexity than it solves.

Removed from message `containerId` as it is the same as `tag`.

The json decoder starts to decode immediately an inotify event is
received.
But at the time the inotify event is trigged, the json log
entry might haven't been fully written to the disk.
In this case the decoder will return an "io.UnexpectedEOF" error, but
there is still data remaining in the decoder's buffer. And the data
should be passed to the decoder when the next inotify event is
triggered.

If an invalid logger address is provided on daemon start it will
silently fail. As syslog driver is doing, this check should be done on
daemon start and prevent it from starting even in other drivers.
This patch also adds integration tests for this behavior.
