Signaling representation format in VPS (MACRO: REPN_FORMAT_IN_VPS)

Includes signaling of representation format - including picture resolution, bit depth, chroma format - in the VPS, with the option of updating them in the SPS. The configuration file has "RepFormatIdx%d" added to indicate for each layer which representation format is used. The rep_format() structures are automatically created by the encoder. If the bit depth and the chroma format are also changed across layers, some more configuration support would be needed.
