Since the seeking byte offset is chosen by linear interpolation
from SCR values, we need to take that first SCR into account
to end up near the correct offset. Otherwise, as the code does
a linear search after that first seek, it will take a LOOOOOONG
time to get there for streams which don't start at zero.

Makes camerabin2 intercept preview-image messages and add
the filename corresponding to the message structure in the
'location' field.
Makes easier for applications to track preview images
Setting the audio source to NULL just after pushing the EOS event
on it could potentially cause loss of said EOS event. Instead, we
can set the audio source to NULL when ready-for-capture is
signalled and the boolean value is true as this indicates we are
not currently capturing video.
header_length contains the length in bytes after the header_length
field, excluding the 6 byte start code and header_length field.
H.264 streams and some other formats need to be announced in the PSM.
VLC wouldn't play files created with mpegpsmux containing H.264 because
we claim the system header is larger than it actually is, which makes
VLC skip the program stream map which follows the system header, which
in turn makes it not recognise our H.264 video stream.
If the preview pipeline fails creation, for any reason, we should
fail basecamerasrc state change.
Also adds a missing g_return_if_fail check to preview pipeline
functions
VP8 uses a probabilistic bool coder, not a straight bit coder.
This fixes parsing when error-resilient is set.
This commit includes a copy of libvpx's bool coder, BSD licensed.

Avoid an extra copy via a temporary fixed size stack buffer.
Use libcelt's header size to allocate a buffer of the correct
size in the first place (libcelt has an off by 4 there, so
account for this).
While there, make size unsigned, and granpos signed.

An element stores the result for the last state change it did and
GstBin's state change handler will use this last result for state
locked elements to decide if its state change was successfull or not.
In camerabin2, the filesinks have their state locked and when they
fail switching states, this last failure will be used if the application
tries to change camerabin2's state, causing any state change to fail.
This patch makes camerabin2 reset this last change failure, avoiding
that camerabin2 fails on its next state changes.
