fc09e45108 codecparsers: VC1: Implement Sequence Layer Data Structures
Instead of having a single VC1SequenceHeader structure, use the 3 structs
from the "Table 265: Sequence Layer Data Structure" of the specification
for the library to be more flexible.

Implement the functions to parse them

acdd2c20f7 basecamerasrc: Set preview pipeline to ready when going to ready
The preview pipeline should go to ready when the camerasrc goes
to ready, as in ready elements shouldn't be processing data.

21653a793a camerabin2: Initialize camerabin2 preview pipeline data with 0
Use g_new0 to initialize all fields with 0 to only cleanup what has been
initialized. This makes cleanup work correctly when some initialization
fails and pointers are left in some inconsistent state.

12f77b27e2 camerabin2: preview: No need for appsink to store the last buffer
There is no need for preview's appsink to keep a reference to the last buffer,
so disable the property to make it unref the buffers sooner.

d41af4e2f8 camerabin2: preview: Remove one of the two colorspace converters
The preview pipeline doesn't need 2 colorspace converters, remove
one to speed up caps negotiation and reduce the delay on getting
the first preview buffer out of the preview pipeline.

It shouldn't cause problems as videoscale and ffmpegcolorspace seems
to handle the same caps, so no conversion should be needed for
videoscale. Additionally, camerabin1 has been working with a similar
pipeline with a single ffmpegcolorspace and no bugs have been open about it
so far.
