* playbin3 does not support {current,n}-{audio,video,text}
properties, and they were replaced by GstStreams API.
So, GstStreams API and select-stream event should be used
for track change in case of playbin3.
see also https://bugzilla.gnome.org/show_bug.cgi?id=769079
* By using commend line option "--use-playbin3", gst-play will
use playbin3 regardless of "USE_PLAYBIN" env variable.

Use new message notify API and print caps and taglists in a nicer
to read way, just like gst-launch-1.0 does nowadays, without
escaping everything three times.
< and > are composed with shift + something else on many keyboards
layouts, so don't work well when injecting them via windowing systems
which will send them as shift key press and separate other key, and
we the don't combine that to < or > properly. n/b are easier.
When g_option_context_parse fails, context and error variables are not getting free'd
which results in memory leaks. Free'ing the same.
And replacing g_error_free with g_clear_error, which checks if the error being passed
is not NULL and sets the variable to NULL on free'ing.

When running gst-play against a directory name, and suffix the path with a
directory separator (e.g. tab completion), gst-play was printing two directory
separators in a row. g_build_filename fixes this, and additionally allows for
both '/' and '\' as separators on Windows.
In case of very short files we might end up seeking in
steps of a fraction of a second, which is silly and gives
the impression that seeking doesn't actually work. Make
minimum seek step a second instead.
For positive seeking segment.stop value will be -1,
when we change rate to -1, then the stop value will be udpated
with the current position. And then again if we change rate to 1,
the segment.stop value does not get updated and remains as position
where we last changed rate to -1. Hence playback stops at that point.
In case of positive rates, call gst_element_new_seek with correct values

Printing 64 whitespaces to erase the "Paused" message (after \r) would make
it wrap to the next line on shorter terminals. Instead we only print the
amount of spaces needed. Also mark the "Paused" string for translation
while we're at it.
Use smaller steps for lower rates to allow more
fine-grained control. Handle jump across 0 properly
from both sides (just flip direction where we would
have gone down to 0 instead). Don't artificially
limit rates to +/- 10x. Print new rate.

First set the pipeline to the PAUSED state to check if we are dealing
with a live pipeline or not. Then move to the desired state.
If we don't do this, it is possible that we receive a BUFFERING message
before we know that the pipeline is live and we would set the pipeline
to PAUSED and deadlock.
