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 Change-Id: I4ecdf41e752454a908d131e76bab113a616f2bc8
