c3a9d2dc64 interlace: add alternate support 
Allow downstream elements to negotiate the alternate interlace mode,
splitting each input buffer in two fields, each having their own buffer.

eb914c127d interlace: rename copy_field() 
It is actually copying both fields (to a single frame/buffer).

812d593c4e interlace: Store unsigned integers in unsigned integer types 
And add some assertions to guard against overflows and out of bounds
reads.

c67146b27a interlace: Increment phase_index before checking if we're at the end of the phase 
Incrementing it afterwards will always have to phase_index >= 1 and we
will never be at the beginning (0) of the phase again, and thus never
reset timestamp tracking accordingly.

This was broken in bea13ef43b in 2010, and
causes interlace to run into integer overflows after 2^31 frames or
about 5 hours at 29.97fps. Due to usage of wrong types for the integers
this then causes negative numbers to be used in calculations and all
calculations spectacularly fail, leading to all following buffers to
have the timestamp of the first buffer minus one nanosecond.

e6c3446d01 interlace: Allow interlaced sink caps, do passthrough 
Allow interlace to receive already interlaced content, if compatible with its
configuration. In that case, it will just do passthrough.

580a94d18b interlace: fix negotiation if filter caps are passed to query_caps 
Make videotestsrc ! interlace ! $anything work again. Problem
was that upstream filter caps were passed which contained
interlace-mode=progressive, which doesn't intersect too well
with interlace's source pad template caps, leading to
not-negotiated errors.

32ba17cd0f Use gst_element_class_set_static_metadata() 
where possible. Avoids some string copies. Also re-indent
some stuff. Also some indent fixes here and there.

1c25aab906 interlace: avoid dividing by zero on unkbown framerate 
If the framerate is unknown, we cannot generate meaningful
buffer timestamps/durations, so set them to _NONE instead of
calculating something wrong and dividing by 0.

0de362f248 interlace: Fix buffer timestamp and duration 
The field rate is twice the frame rate of the src pad and so the duration of
one output buffer is src_fps_d / (2 * src_fps_n).

341b0c2d62 interlace: Rename pattern property to field-pattern 
This is mostly for clarity of what the property means and, I believe, makes the
pattern-offset property more comprehensible.

bea13ef43b interlace: Add pattern offset property 
This property allows one to start at any point within the field pattern after
a discontinuity (whenever gst_interlace_reset () is called). Thus with the
2:3:3:2 pattern, for example, one can start at offset 2 and achieve 3:2:2:3
or offset 1 and achieve 3:3:2:2.
