Need to emulate MAX_VARYING_VECTORS/MAX_FRAGMENT_UNIFORM_VECTORs/MAX_VERTEX_UNIFORM_VECTORS for glGet

[Zhenyao Mo]

In desktop gl, the corresponding enums are MAX_VARYING_FLOATS/MAX_FRAGMENT_UNIFORM_COMPONENTS/MAX_VERTEX_UNIFORM_COMPONENTS.

The difference is a multitude of 4.

 +          *value /= 4;
nit: you should explain this factor of 4 in the ChangeLog.  desktop GL returns
byte counts or something, and GLES2 needs to return 32bit word counts?
