opengl emulator: Added gl error tracking on the guest (encoder)

Browse Source 
Sometimes we need to check parameter values before encoding
to prevent crashes, for example:
glDeleteBufferes(-1, ptr); - would crash
For that we need to check some gl errors on the guest.

The change adds error state to the encoder and also
adds new feature to emugen which allows to insert
parameter check code into the attribute file.
Added such parameter check code in the appropiate
gl functions in gl.attrib and gl2.attrib
