60a6eca2a1 camerabin: Adds 'idle' property
Adds 'idle', a read-only boolean property that tells applications
if there is any capturing/saving/encoding going on in camerabin. If
not, it is safe to set it to NULL and release resources without
losing data.

6ee256d462 camerabin: Store app preferred capture parameters separately
Store width/height/fps for video captures in a separate variable
than the one that stores the currently used value.

This prevents the user preferences to be lost when resetting
the currently used dimensions for night mode, for example

c48de5c594 camerabin: Add video-capture-width/height/framerate properties
Adds video-capture-width, video-capture-height and
video-capture-framerate properties to allow applications to
get/set those values. Getting was not possible before this patch,
and setting was done through the set-video-resolution-fps
action, which sets the properties and promptly resets the
video source to use them.

Fixes #614958

Adds image-capture-width and image-capture-height properties
to camerabin, allowing the user to get/set them. Getting was
not possible before and setting was done through the
set-image-resolution action, which shouldn't now just set
the properties.

55d98ef488 camerabin: add block-after-capture property for viewfinder blocking
Adds block-after-capture property to block running viewfinder after capturing.
This property is useful if application wants to display capture preview and avoid
running viewfinder on background.

d25a9ca8aa camerabin: add video-source-filter property
Add video-source-filter property that can be used to inject application
specific gstreamer element to camerabin pipeline. The video-source-filter
element will process all frames coming from video source.

One could add image analyzers to collect information about the stream,
or add image enhancers to improve capture quality, for example.
