de138dbc57 basecamerasrc: optimize state changing speed 
Create preview pipeline already in initialization phase. This speeds
up NULL_TO_READY state change. Also implement a separate function for
setting the preview filter element.

This also restricts the preview filter property to work only on
NULL state.

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,

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.
