This commit fix several issues with sequence layer header forging on
update_caps():
- 0x00000004 unsigned integer is before STRUCT_C.
- Set reserved bits of STRUCT_C to their values for simple/main
profiles in sequence layer header format and ASF header format.
- Sequence layer shall be represented as a sequence of 32 bits unsigned
integers and shall be serialized in little-endian byte order except
for STRUCT_C which shall be serialized in big-endian byte-order.
See SMPTE 421M Annex L for more details about sequence layer format.

packet_length is defined as a guint16 in the PESHeader structure. This
definition match the specification. But since we add 6 bytes to the
packet_length value (length of start_code + stream_id + packet_length),
we can overflow the guint16 when the value in the PES header is greater
than 65529.
So use a guint32 instead of a guint16 to avoid overflow.

This thread dispatches navigation events. It is needed to avoid deadlocks
between window backend threads that emit navigation events (e.g. X11/GMainLoop
thread) and consumers of navigation events such as glimagesink, see
https://bugzilla.gnome.org/show_bug.cgi?id=733661
GstGlWindow_x11 thread is changed to invoke the navigation thread for navigation
dispatching, instead of emiting the event itself. Othe backends beside X11 do
not dispatch navigation events yet, but should use this thread when dispatching
these events in the future.
The navigation thread is currently part of GstGLWindow and not implemented in
separate subclasses / backends. This will be needed in the future.
gst_gl_window_x11_get_surface_dimensions is also changed to use a cached value
of the window's width, height. These values are now retrieved in the X11
thread, function gst_gl_window_x11_handle_event. This change is needed because
otherwise the XGetWindowAttributes gets called from the navigation thread,
leading to xlib aborting due to multithreaded access (if XInitThreads is not
called before, as is the case for gst-launch)

face detection will be performed only if image standard deviation is
greater that min-stddev. Default min-stddev is 0 for backward
compatibility. This property will avoid to perform face detection on
images with little changes improving cpu usage and reducing false
positives

This still has some unit tests for alternative renditions and
seeking, which are commented out for the time being until we
support them properly.
In gst_data_uri_src_create(), buf cannot be NULL, hence
else if (*buf != NULL) will be invalid so removing the
else if condition and adding a check to unreference buf
in else condition, just in case

The first buffer does not contain more garbage than any other MP3 decoder
outputs and we don't really know how much we have to drop or not.
After this change the output has the same duration as with mad.

all above 3 functions do the same functionality except for offset and pixel stride.
Hence moving the functionality to a single funtion.

Valid values range from 1 to 7 as stated.
DTV_ISDBT_LAYER_ENABLED bitmask is built from
OR-ing 0x1 0x2 0x4. If all bits are set
(0x00000111 = 7) it means all layers should be
demodulated.
Do more elaborate validation of the input caps: what fields
are required and/or not allowed. Don't assume AVC3 format
input without codec_data field is byte-stream format. Fix
up some now-unreachable code (CID 1232800).
