Add compression support in EGPRS PUAN
This adds compression of bitmap in PUAN. The compressed bitmap is used only if the number of bits in the bitmap does not fit in the message and there is a gain after compression. The algorithm is part of libosmocore and so there is dependency on the libosmocore for compilation. The algorithm is tested on integration setup by forcing compression.
