c98348c141 adaptivedemux: track per-fragment bitrates. 
And use the average to go up in resolution, and the last fragment
bitrate to go down.

This allows the demuxer to react rapidly to bitrate loss, and
be conservative for bitrate improvements.

+ Add a construct only property to define the number of fragments
  to consider when calculating the average moving bitrate.

783245f1fe videoaggregator: fix buffer selection when duration=-1 
If the src framerate and videoaggreator's output framerate were
different, then we were taking every single buffer that had duration=-1
as it came in regardless of the buffer's start time.  This caused the src
to possibly run at a different speed to the output frames.

Min latency can never be invalid, latency property can never be invalid
either. So no need to check for all these things in various places.

ef8e5280d0 aggregator: Don't add the latency property to the max latency 
It has no meaning for the max latency and is only used to increase the min
latency.

7d46357627 gstglwindow_cocoa: fix slow render rate 
In gst_gl_window_cocoa_draw we used to just call setNeedsDisplay:YES. That was
creating an implicit CA transaction which was getting committed at the next
runloop iteration. Since we don't know how often the main runloop is running,
and when we run it implicitly (from gst_gl_window_cocoa_nsapp_iteration) we only
do so every 200ms, use an explicit CA transaction instead and commit it
immediately. CA transactions nest and debounce automatically so this will never
result in extra work.

5f547c5600 gl: initial support for texture targets other than GL_TEXTURE_2D 
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

API: modify GstGLMemory
API: modify gst_gl_memory_wrapped_texture
API: gst_gl_download_perform_with_data

1a07467d5f aggregator: Make the PAD_LOCK private 
Instead of using the GST_OBJECT_LOCK we should have
a dedicated mutex for the pad as it is also associated
with the mutex on the EVENT_MUTEX on which we wait
in the _chain function of the pad.

The GstAggregatorPad.segment is still protected with the
GST_OBJECT_LOCK.

Remove the gst_aggregator_pad_peak_unlocked method as it does not make
sense anymore with a private lock.
