opengles emulator: fix glGetUnifrom

added state tracking for uniforms in program objects
for each active uniform in index i we will save its starting location
,size and type, so when calling glGetUniform on its location,
we can tell how many bytes we should read from the stream according to
the uniform's type

add some type and size definitions to functions
that calculate size from enum

some other fixes to the codec
