The target texture of an EGLImage is the texture bind just
before calling glEGLImageTargetTexture2D.
As we currently only support a gl texture as the source of an EGLImage
the gl texture is actually already allocated when creating the eglimage.
I also see some cases where it fails to upload an eglimage when
glTexImage2D is called on the target.
GST_GL_WINDOW is used for window system specific choices.
An EGLDisplay can be created from window systems with egl support by using
eglGetDisplay().

This commit makes the loading of the GModules threadsafe, and
always first tries to load the symbol for the GL library that
is selected for the current context. Only then it falls back
to looking into the current module (NULL), and only as a last
resort the context specific function (e.g. eglGetProcAddress())
is called.
Also add configure parameters to select the names of the library
modules instead of using the defaults, and let the defaults be
independent of the G_MODULE_SUFFIX.

Previously, we used the width to determine the amount of data to be
copied using pbos. This, makes it allocate enough data for the
the strides as well.
Most of our 2D filters use the same simple vertex shader.
Also define the default fragment shader as the identity.
Avoid duplicating the same vertex and fragment shader text.
When parsing slice groups information for slice_group_map_type = 2, we
should only be reading up to num_slice_groups_minus1 groups since there
is always a "leftover" slice group and as many "foreground" slice groups
as needed.
This fixes parsing for SVCBMT-5 and SVCBMT-12 whereby the base layer would
have incorrectly been parsed to have up to 38 reference frames in list0,
which is not possible.

When useDefaultScalingMatrixFlag is computed to be 1 while parsing
scaling_list(), then the scaling list shall be inferred to be equal
to the default list (7.4.2.1.1.1). That default list is really one
of Default_4x4_{Intra,Inter} or Default_8x8_{Intra,Inter} and not
one from fall-back rule sets A or B.
This fixes parsing for FRExt1_Panasonic_D, FRExt2_Panasonic_C,
FRExt3_Panasonic_E and FRExt4_Panasonic_B.

This should fix QoS problems, where basesink believed it was rendering with
20FPS but actually we were just queueing up X11 Expose events and only once
in a while something was rendered.
I was lucky that:
e1 = vc_dispmanx_element_add ()
eglCreateWindowSurface (e1)
vc_dispmanx_element_remove (e1)
e2 = vc_dispmanx_element_add ()
resulted in having e2 equal to e1. And also having the egl surface
that does not allocate its buffers before the first draw.
It avoids to draw to an invalid buffer.
Withtout this the default frame buffer is undefined:
glBindFramebuffer (GL_FRAMEBUFFER, 0)
Visually you could see some white frames at the beginning
when lunching videotestsrc ! glimagesink
With OpenGL Profiler from XCode you could see some
GL_INVALID_FRAMEBUFFER_OPERATION for the first frames
