Get a sense of files and line numbers in the parsed GstStructure
and take that information when reporting GstValidateAction errors
by letting the user know where the action comes from in the messages.
And accept non-literal string in printing formats.
Since `,` is the separator between fields of GstStructure we can
safely consider that if a line ends with it, the following line
is the logical continuity of the serialized GstStructure.
This makes writing those files more convenient and reading them
more pleasant as we do not need to add extra `\` at end of lines
anymore
Added two properties to the plugin:
* ignored-event-types: A list of event types to be ignored when logging events
* logged-event-types: A list of event types to be logged when logging events
This commits also moves the "ignored-event-fields" property to using a proper
GstValueList for the list of event fields to be taken into account, instead
of the home grown separated by comas list of string, making the API more
uniform.
This also adds a simple helper method: `gst_validate_utils_get_strv`
`gst_pad_pull_range` should always be called from the streaming thread,
we now check that when pull_range is called, and if the sinkpad calling
the function has a GstTask with a running thread, the function is called
from that thread.

The way this was implemented was simply wrong, first of all checking
the position against the segment after a seek in PAUSED by a query
of the pipeline position is of limited interest, and can only work
in forward playback.
Furthermore the check was a huge blob of code that didn't even look
like it was pretending to do a good job at checking the position in
reverse playback.
This also adds the notion of global variables which will be useable
in config files too.
And add some documentation about default variables in scenarios
Meaning that instead of getting 1 "Detected on" line per monitor,
there will be one per "branch" like:
Detected on <audioconvert1:sink, audioconvert1:src, audioresample1:sink, audioresample1:src, smart-adder-adder:sink_0, smart-adder-adder:src, smart-adder-capsfilter:sink, smart-adder-capsfilter:src, capsfilter2:sink, capsfilter2:src, tee1:sink, tee1:src_0>
Making it simpler to read and a bit less verbose.
The action is generally useful but was implemented in a way that
was restricting its usage for no good reason. Refactor the
implementation adding more argument so it can be used in a wider
context, such as uvch264src.
Something like:
``` bash
echo "video-request-key-unit, direction=upstream, all-header=true, count=1, target-element-factory-name=h264parse, srcpad=src, playback-time=1.0" > tmp.scenario && \
echo "stop,playback-time=2.0" >> tmp.scenario && \
gst-validate-1.0 --set-scenario=tmp.scenario uvch264src \
device=/dev/video0 name=src iframe-period=33 auto-start=true src.vfsrc ! queue ! fakesink \
src.vidsrc ! queue ! video/x-h264,width=1280,height=720,framerate=30/1 ! h264parse ! fakesink
```
works now.
So it can be used directly in the documentation Also add a special "all"
argument to `gst-validate-1.0 --inspect-action-type` so we can generate
the documentation for all action types easily.
_Q_VALIDATE_MONITOR was defined twice because it wasn't declared
as extern in the header, so it would be defined as variable in all
included files. This doesn't seem to cause problems on Linux, but
seems to cause build failures on macOS.
Fixes#42
Basically nothing guarantees that the set of pads we aggregated the flow
for is the same as the one that was aggregated during the actual data
flow as some pads could have been removed meanwhile.
