Matthew Waters d86208e6ad glvideomixer: bas output width/height on the pad properties 
Allows automatic negotiation of the size in the following case:
gst-launch-1.0 glvideomixer name=m sink_0::xpos=0 sink_1::xpos=320 ! glimagesink \
    videotestsrc ! m. \
    videotestsrc pattern=1 ! m.

Matthew Waters 3e092e1579 gl: XInitThreads when env variable is set 
This is too allow gst-launch debugging with multiple GL contexts as
well as avoiding segfaulting innocent gtk+ apps that have not called
XInitThreads.

Matthew Waters bcce615263 gl: add a scary note about initializing thread support for the winsys 
We cannot do it as the winsys may crash if we initialize too late.

Example, GLX contexts with Intel drivers:
Intel requires the X Display to be the same in order to share GL
resources across GL contexts.  These GL contexts are generally
accessed from different threads.  Without winsys support it is
nearly impossible to guarentee that concurrent access will not
occur.  This concurrent access could result in crashes or abortion
by the winsys (xcb).

Also fixes dynamically adding and removing pads while glmixer is
in a state >= PAUSED.

Matthew Waters 5433010ab5 gl/wayland: create a dummy display instead of an EGLDisplay 
Currently, GstGLWindowWaylandEGL holds the wayland display connection
If we create the EGLDisplay at the GstDisplay creation time, then
libEGL will internally open another connection to the wayland server.
These two display connections are unable to communicate resulting in
no window output/display and hangs inside libEGL.

Eventually we will move the wl_display from GstGLWindow to GstGLDisplay.

Matthew Waters 57a54e9de4 glupload: always release the previous buffer 
Fixes the case where _perform_with_buffer() is called without
intervening calls to _release_buffer() as is the case on start up
with glimagesink.

Also release the buffer when reseting the upload.
