ae86dec9ca videorate: Detect framerate if not forced to variable downstream
In case upstream does not provide videorate with framerate information,
it will detect the current framerate from the buffer it received,
but if downstream forces the use of variable framerate (most probably
through the use of a caps filter with framerate = 0 / 1), videorate will
respect that.

And add some unit tests

b9b5b133fd videorate: Add a max-rate property
In various use-case you want to dynamically change the framerate (e.g.
live streams where the available network bandwidth changes). Doing this
via capsfilters in the pipeline tends to be very cumbersome and racy,
using this property instead makes it very painless.

2c1bf82d55 videorate: Fix behaviour for frame rate cap changes
The outgoing buffer timestamp is calculated by scaling an output buffer
count by the src pad frame rate caps. If these caps change, we need to
reset the count and work from a new base timestamp. The new output
buffer timestamp is then the count scaled by the new caps values added
onto the base timestamp.

f35c5bc1e7 videorate: Make videorate work with a live source
Add a property that makes videorate skip to the first buffer it
receives instead of padding the stream from segment start to the
first real buffer.

Fixes bug #567928.

956c9f32a3 videorate: handle invalid timestamps better
Handle buffers with -1 timestamps better by keeping track of the en time of the
previous buffer and assuming the -1 timestamp buffer goes right after the
previous one.

when we have two buffers that are equally good, output the oldest buffer once to
minimize latency.

don't try to calculate latency when the input framerate is unknown.

915b3d139d videorate: clear discont on duplicated buffers
When videorate duplicates a buffer with a DISCONT flag, it copies the discont on
the first pushed buffer but fails to clear it for subsequent buffers. This
causes theoraenc!oggmux and possibly other elements to consider this a discont
stream.

Fix videorate to produce discont as the first buffer and after a flushing seek.

Fixes #580271.
