15391b29e1 mpegtsdemux: push based seeking based on PCR
buffer timestamps are converted to GstClockTime to cover pcr/pts wraps.
multiple pcr/pts wraps are handled with an index which ensures at most
a single pcr wraparound between two entries.
the last seen pcr is recorded to have a nearby index point for short seeks
resuming playback might be delayed if the postion is not a keyframe

TODO: replace manual packet scanning and parsing in the initial duration estimation

2271946d73 basescope: allow subclasses telling how many sample they need per frame
This allows e.g. FFT based elements to require enough data. If they need more
data than what we get, we flush less from the adapter.

813ac7bb2d mpegvideoparse: Avoid double scanning of pictures
The incoming data has already been scanned in mpeg_packetizer_add_buf.
We can therefore stop scanning for picture data as soon as we've parsed
the header. Makes mpegvideoparse 2 times faster.

23576af52a camerabin2: Adding a filter to wrappercamerabinsrc
Camerabin2 allows setting a filter for image, video or viewfinder, but
not one filter for all three at the same time. I added a filter to
wrappercamerabinsrc to allow setting a global filter when using this
source.

db7fe611ed bayer2rgb: Convert to Orc
Seriously faster.  Algorithm is nearly the same as bilinear, which
given the speed of this code, should be considered the baseline of
quality.  Speed appears to be limited by memory bandwidth, so I
didn't bother trying to make it any faster.
