9863feb328 camerabin2: Implement previewing
Implement previewing functionality using 2 properties. A boolean
(post-previews) that indicates if previews should be posted, and a
GstCaps (preview-caps) to provide the desired preview caps.

wrappercamerabinsrc implements previewing by supplying the captured
image to a pipeline to adapt it to the required caps before posting.

203508079a camerabin2: Fix renegotiate event pushing
Use a hack to make the event upstream to reach the camera source
instead of going downstream and being useless.

This was already fixed this way for image srcpad renegotiate and
video srcpad was left unfixed.

1e6be5ec56 camerabin2: Use custom renegotiate event
Adds a custom renegotiate event that is pushed to the camerasrc pad
that needs renegotiation due to the user selecting a new capture
caps for that pad.

This is a way of notifying the source that it should update its caps, even
if it doesn't use pad allocs.

by name when needed later.

014b8f97f8 viewfinderbin: Fixes to video-sink handling
Handle video-sink more carefully, checking if it should
be already added to the bin, and removing old ones when
replacing.

b11342d325 camerabin2: Reset all elements on video recording branch before capture
We need to reset the elements from the video recording branch, including
the queue and capsfilter in order to clear the eos state and activate
the pads.

This makes it possible to record multiple videos with camerabin2 in a
sequence, otherwise the source would get a unexpected return and
push EOS, stopping the whole pipeline.

122a7bd556 camerabin2: Various fixes
As video recording bin's state is locked, we should always
remember of setting it to NULL when camerabin2 goes to NULL

Be more careful when using elements that might not
have been created yet

And do not set location property recursively on videorecordingbin

ba878c95b2 camerabin2: adds location property
Adds a location property to enable applications to select
the captured files names. Locations are handled just like
multifilesink ones

Also disables -Wformat-nonliteral to allow to use non-literals
on g_strdup_printf on camerabin and generate a sequence of
locations for captures.

cb915196e2 camerabin2: Handle vidbin state change individually
Keep vidbin state locked to avoid it going to playing without
being used and leaving an empty file created.

Check the docs on the code for details on the handling.

0ae8df4312 camerabin2: Keep it under --enable-experimental

bd89d22da9 camerabin2: Update v4l2camerasrc to use start/stop signals
Removes the old logic for v4l2camerasrc that used the mode
property switching to start/stop captures to make it identical
to camerabin2 behavior and to allow the future addition of
pausing a video recording.

This also removes the MODE_PREVIEW as it became useless.

6c7d7946f5 camerabin2: Keep mode definition at -enum file
Use 'mode' enum definition from gstcamerabin-enum file to avoid
conflicts between v4l2camerasrc and gstcamerabin2 modes.

For now there is a MODE_PREVIEW there that is only used on the
camerasrc, not sure if we are keeping it at the future, but for
now this works.
