Move calling gst_vtdec_push_frames_if_needed from ::set_format to ::negotiate so
that we always drain even when renegotiation is triggered by downstream.
vtdec specifies sysmem; GLMemory as template caps. When negotiating, we used to
call gst_pad_peer_query_caps (..., filter) with our template caps as filter. The
query does gst_caps_intersect (filter, peercaps) internally which gives
precedence to the order of the filter caps. While we want to output sysmem by
default, when negotiating with glimagesink which returns GLMemory; sysmem; we
do want to do GL, so we now query using a NULL filter and intersect the result
with our template caps giving precedence to downstream's caps.
tl;dr: make sure we end up negotiating GLMemory with glimagesink
If for some reason the avdtpsink element can't go READY then the
gsta2dpsink can't either and so should release the ressources it
allocates when trying to do so.
Fix a leak with the generic/states test.

Similar to vtdec_hw, this commit adds a vtenc_h264_hw element that fails
caps negotiation unless a hardware encoder could actually be acquired.
This is useful in situations where a fallback to a software encoder
other than the vtenc_h264 software encoder is desired (e.g. to x264enc).

When renegotiating mid stream - for example with variable bitrate
streams - and therefore destroying and recreating VTSessions, the
hw decoder might become temporarily unavailable.
To deal with this and avoid erroring out on bitrate changes,
vtdec_hw now falls back to using the software decoder if the hw
one was available at some point but isn't anymore. At
renegotiation/bitrate change time, it will still retry to open
the hardware one.
::negotiate can be called several times before the CAPS event is sent downstream
so use the currently configured output state caps instead of the pad current
caps when deciding whether to recreate the VTSession or not.
This leads to creating/destroying less VTSessions which makes renegotiation more
reliable especially when using hw decoding.
There's no need for an end-of-list marker in the filter
PIDs array if full, as the absolute maximum number of
elements (MAX_FILTERS) is known.

This bug was found via cppcheck static analysis.
If android.hardware.Camera.getParameters returns NULL, then object will
be NULL, and we won't allocate params. This means that the GST_DEBUG
statement referencing params->object will be invalid. Fix this by
exiting early if android.hardware.Camera.getParameters returns NULL.

There is no way to tell one over the other when parameters
seem valid for DVB-T and DVB-T2 and the adapter supports
both. Reason to go with the former here is that, from
experience, most DVB-T2 channels out there seem to use
parameters that are not valid for DVB-T, like QAM_256
https://bugzilla.gnome.org/show_bug.cgi?id=765731
DVB-T/T2 have the same number of fields so we were
wrongly assuming DVB-T for DVB-T2 broadcasts. Not
setting the delivery system here allows for dvbsrc
to make an informed guess based on the channel
parameters.
