vtenc: Fix locking
...
The object lock only protects the session, as we modify
the session from other threads when the bitrate property
is changed. Don't hold it much longer than for session
related things.
And we need to release the video decoder stream lock before
enqueueing a frames. It might wait for our callback to dequeue
a frame from another thread, which will then take the stream
lock too and deadlock.

It is not required on OSX apparently and was only added in 10.9.6 there.

just not set a level at all here.

vtenc: Fix encoder to work on iOS

iOS has special stride requirements that we don't know yet, so copy
input buffers into buffers allocated by iOS for now.
Later we should check the stride and probably provide a buffer pool for these
buffers so upstream can directly write in there.

vtenc: Avoid leaking caps object and its copy
...
gst_pad_get_pad_template_caps() returns a reference which is unreferenced,
so creating a copy using gst_caps_copy() results in a reference leak. Also
the caps are pushed as an event downstream, but this doesn't consume the
caps so it must still be unreferenced.
