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.

1c74f22264 camerabin: don't try adapting image capture resolution if no source-resize flag
If source-resize flag is disabled then set resolution to image capture caps
according to capture resolution video source element produces. Otherwise we
write wrong resolution to image metadata.

regardless of the element state.

1b10553f90 camerabin: improve image done signal emission
Use g_idle_add_full() with G_PRIORITY_HIGH to emit image done signal,
g_idle_add() is more likely to starve with higher priority events.

b890ecd83c camerabin: code cleanups

7b62e11412 camerabin: don't reset capsfilters or zoom if error occurs
If an error occurs, application should set pipeline to NULL, and updating
zoom can actually block message handling if video device driver has failed
and video src element supports zooming using photography interface and S_CROP.

7992233522 camerabin: Fix compilation on Windows with Visual Studio
Windows doesn't have strcasecmp so we should use

Also Windows doesn't have sys/time.h so we first
need to check if it actually exists and if not
we should not include it.
