Print details about the descriptions when listing scenario in a KeyFile
format
The description can contain any information about the scenario such as its duration before
EOS, how long the pipeline needs to be so the scenario can be applied...etc
GST_VALIDATE_SCENARIOS_PATH was used only for loading scenarios,
so any in that path would not be listed by -l.

In case we have serialized events right after a buffer that had no
timestamp set we concider that last timestamp was 0, but we can
actually not concider the timestamp at all in that case as it is
only "meaningless value".
This make it easier for user to understand the difference between
the two concepts and avoids confusion.

This action can be used to change the rank of a particular element,
so you can force a particular element to be used when using
autoplugging elements (such as decodebin, encodebin, and friends)
This type of actions is used to change some parametter on GStreamer
core and it plugins, it can be fore example, to change the rank of a
plugin or things like that.
It is a random number, but it will in most cases give people a hint
that gst-validate reported a critical issue, and thus set the return
code, only by looking at it
Also make use of gst_validate_runner_print() in
gst-validate-transcoding.c as we were copy pasting that method there.
Always keep probing the pipeline for the current position and compare
with the latest requested seek segment to detect if the seek boundaries
are being respected
The "switch-track" command can be used to switch tracks. The "type"
argument selects which track type to change (can be "audio", "video",
or "text"). The "index" argument selects which track of this type
to use: it can be either a number, which will be the Nth track of
the given type, or a number with a "+" or "-" prefix, which means
a relative change (eg, "+1" means "next track", "-1" means "previous
track").

When used with LD_PRELOAD, the application might use various pipelines
for several different thing, we need to make it possible to spcify a
specific pipeline (or set of pipelines) on which to run the scenario.
The format is in the form of:
scenario_name:pipelinename_pattern*
