Move rpicamsrc from https://github.com/thaytan/gst-rpicamsrc/

It's a useful little element and works well, so might as well
make sure it's widely available so people can stop piping
raspivid output into fdsrc.

cab6585378 rpicamsrc: Expand frame timeout from 100ms to 500ms 
rpicamsrc on a normal rpi camera doesn't start up fast enough,

might be to have a longer timeout for the first frame, but
shorter once frames are running - but this quick fix will at
least make rpicamsrc work again.

b45e239128 rpicamsrc: RaspiCapture: use mmal_queue_timedwait() for buffer queueing 
If an external camera was disconnected, there were no feedback in an
application. It seems reasonable to wait on mmal_queue no longer than
100ms. If it's stuck we just return a FLOW_ERROR and let the application
decide what to do later.

ed893592ea rpicamsrc: Implement use-stc property to disable STC timestamps 
If use-stc=false, then rpicamsrc won't apply
the camera timestamping to outgoing buffers, instead
relying on real-time timestamping by the
GStreamer clock. It means slightly less accuracy
and more jitter in timestamps, but might help on some
CSI inputs with broken timestamping.

ca61a76987 v4l2: Fix threading issues in orphaning mechanism 
The pool orphaning function was colling internal _stop() virtual function
implementation. This is not thread safe, as a private lock inside the buffer
pool is supposed to be held. Fix this by keeping delayed _stop() and orphaning
the GstV4L2Allocator instead (REQBUFS(0)).

Then, protect the orphaned boolean with the object lock for the case a buffer
is being released after we have orphaned the buffer. That would otherwise
cause a QBUF to happen while the queue is no longer owned by the buffer pool.
This boolean is otherwise used and set from the streaming lock, or after
threads have been stopped (final cleanup).

83f60aea54 v4l2bufferpool: Only resurrect the right amount of buffers 
On streamon, we need to resurrect (queue back) some buffers, as during
flushign seek we'd endup with an empty queued. We initially started with
resurrecting as many as we could without blocking, but that miss-behaved with
dynamic CREATE_BUFS, causing the pool to grow dramatically. This was limited
by the number of allocated buffers, but this still tried to resurrect too many
buffers for the first run, as activating the pool will queued buffers.

In this patch, we calculte the missing detal in the queue and only try and
resurrect that amount of buffers.

b8f1f2195e v4l2bufferpool: Avoid set_flushing warning 
The gst_buffer_pool_set_flushing() warns when that function is called
on an inactive pool. Avoid the warning by checking the state, this is
similar to what we do in gst_v4l2_object_unlock().

0344c50eaf v4l2allocator: Fix data offset / bytesused size validation 
The check was too strict causing spurious warning. Now check for <= so that 0
sized buffer do not cause a warning.

7bbe4653a4 v4l2videoenc: Skip negotiation of profiles/level if no codec 
The codec structure is optional and not used for fwht test codec. This
was leading to a crash dereferencing NULL pointer.

3e2420361a Use gst_element_class_set_metadata when passing dynamic strings 
gst_element_class_set_metadata is meant to only be used with
static or inlined strings, which isn't the case for the 2 elements
here resulting in use-after-free later on.

3ea71a63f6 v4l2: videodec: Fix broken template caps 
The profiles and levels were applied to the common caps instead of the copy.
That had the side effect of setting profiles/level from one CODEC onto
another. Leaving to encoder not being registered or not-negotiated errors.

d93664d65d v4l2: codec: Fix GValue leak 
The levels and profiles probe function returned a dynamically allocated GValue
that was leaked. Simplify this by using a stack allocated GValue and a boolean
return value.

bfb1506381 v4l2src: Ignore non-increasing sequence number 
With older kernel, older driver or just broken drivers, the sequence number
may not be increasing. This simply ignore the sequence in this case. This
would otherwise miss-leading large amount of lost frame being reported.

Fixes #729

fbd4afc64c meson: Pass native: false to add_languages() 
This is needed for cross-compiling without a build machine compiler
available. The option was added in 0.54, but we only need this in
Cerbero and it doesn't break older versions so it should be ok.
