d57808385c gstgl: Re-enable WINAPI on _MSC_VER 
The calling convention may be deprecated, but we still need it for
OpenGL. The build issue was caused by an incorrect syntax being used for
the WINAPI (__stdcall) prototype in function pointers which was accepted
by GCC but is rejected by MSVC.

ccbf43987f glshader: add glBindFragDataLocation 
There are some cases where it's needed for binding in/out variables in shaders.
e.g. glsl 150 (gl 3.2) doesn't support the 'layout (location = ?)' specifiers in
the shader source so we have to bind them ourselves.

fdca1dec0d glshader: some compatibility changes for GL 1.4 
GL 1.4 (with GL_ARB_shader_objects) doesn't have glIsProgram or glIsShader
equivalents.  As they are simply assertions, skip them when there isn't a
valid function pointer.

bc8d272aad gstglshader: cache uniform locations 
Avoid redundant calls to glGetUniformLocation. The results can be cached once
the shader has been linked.

148940c456 glshader: don't read invalid list pointers (use after free) 
gst_gl_shader_detach_unlocked already removes the list entry so attempting to
use the element to iterate to the next stage could read invalid data.

Based on patch by Vineeth TM <vineeth.tm@samsung.com>

117fc0409a glshader: properly unref the stages on failure 
When failing in the varargs functions, all the stage objects not handled need to
be unreffed to prevent a leak.

f688a8f0b2 glshader: port to using GstGLSLStage objects for string management 
A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program.  The uniform/attribute
interface has remained the same.

675f789871 glshader: attempt to detect the gles2 inside opengl3 case 
This is necessary to use gles2 shaders in a GL 3 core context on
OS X which fails without a proper #version being set on the shaders.

It doesn't make sense to query for vertex attributes without a vertex
shader. Moreover this is causing a crash on OSX.
