678064d603 timecodestamper: Rewrite element API and code flow
We now have a single property to select the timecode source that should
be applied, and for each timecode source the timecode is updated at
every frame. Then based on a set mode, the timecode is added to the
frame if none exists already or all existing timecodes are removed and
the timecode is added.

In addition the real-time clock is considered a proper timecode source
now instead of only allowing to initialize once in the beginning with
it, and also instead of just taking the current time we now take the
current time at the clock time of the video frame.

c01afab9f7 timecodestamper: LTC from audio
Add support for parsing linear time code from
an audio source using libltc

https://github.com/x42/libltc

The user can now choose between 3 different and independently
running timecode sources. The old override-existing property
has been replaced by timecode-source.

fc2ca69c25 timecodestamper: Remove clock-source property
Remove clock-source property, because the GST clock usually starts at
some random value and is thus uselsess for creating a timecode from it.

b16cd484bf timecodestamper: Post element message with current timecode
timecodestamper will post an element message which contains the current
timecode it just stamped. If a timecode was already found and not
replaced, it will still post it in a message.

a2c6e2b64a timecodestamper: New element to attach SMPTE timecode to buffers
The timecodestamper element attaches a SMPTE timecode to each video buffer.
This timecode corresponds to the current stream time.
