26553bfb1d camerabin: Preserve unused imagebin or videobin on NULL
If video or image mode is never selected then respective bin is in NULL state.
Preserve this state when resetting camerabin from PAUSED to READY.

9c5863ad35 camerabin: don't rely on the application running the default GLib main loop
Don't use g_idle_add() and friends to schedule things we can't do from the
streaming thread in another thread. The app may not be running the default
GLib main loop. Instead, just spawn a thread.

Also, we need to care for when acessing a pad variable, as another thread
might have taken camerabin to NULL while this gst_camerabin_imgbin_finished
didn't run.

6a4be5a2ba camerabin: Processing should stop on READY
The videobin and imagebin from camerabin have their states
locked and aren't put to READY when all the rest of camerabin
is set to it.

This might cause one of them to be still processing and post
an EOS after camerabin isn't expecting it anymore, this causes
an assertion as the processing counter would already be 0 and
would be decremented.

07279bac7b camerabin: mode can be only image or video
No need to check if camerabin is on video mode if it isn't on
image mode as those are the only 2 modes available.

Additionally, if mode gets corrupted somehow and would be neither
image or video it would cause a null pointer dereferencing some
lines of code below, so this is safer.

e96b8a7b5f camerabin: Avoid assertion on image finishing
As imgbin_finished() is scheduled from g_idle_add, it might
be run a little later than expected, this can lead to the application
setting camerabin to ready before imgbin_finished() runs. In this case,
the processing counter goes to 0 and an assertion happens.

This patch relaxes the imgbin_finished() check on the processing
counter.

5c2f805199 camerabin: Create imagebin elements when image mode is set in camerabin NULL state
This patch refactors imagebin element creation and linking into separate functions,
and adds re-using also for imagebin internally created elements.

So this refactoring allows creating imagebin elements already in NULL state when
application sets the image mode, and next state change from NULL to READY will be faster.
This reduces first capture latency.

Earlier the elements were both created and linked in NULL to READY state change.

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.

bc1b09c1c4 camerabin: Add "ready-for-capture" property
Add "ready-for-capture" property to indicate if preparing a new
capture is possible.

"ready-for-capture" changes before the 'image-done' signal, so
the application can be notified that it can do a new capture
even before the previous one has finished encoding/saving.

618f32ad8d camerabin: Reset pre-night-mode stored fps when mode changes

0999fdb82a camerabin: Check the source scene mode when creating it
As camerabin only gets notified of the changes from the

5cb8164938 camerabin: Do not wrongly fail when starting a capture
If the elements are in NULL/READY and changing state to
PAUSED/PLAYING while a capture is started
camerabin might not set the active_bin properly causing the
capture start to fail.

This patch fixes it by checking the current and pending state
of the branches instead of only the current one
