Reset WaveFrontSynchro, WaveFrontFlush and WaveFrontSubstreams to 0, 0, 1 for default common condition conformance.

reset the tiles parameters in the configuration files to enable only one tile per picture to be conformant with the common condition

Move tile markers out of emulation prevention process. Fix for wavefront + independent tile byte alignment. Fix for encoder crash when tiny slices/entropy slices present. Fix for tile marker insertion logic.

change the way in which tiles parameters are encapsulated into the bit stream. Previously we used fixed length code for all tiles parameters, but currently we use variable length code for some of them.
