Original commit message from CVS: * ext/speex/gstspeexdec.c: (speex_dec_chain_parse_data): * ext/speex/gstspeexdec.h: * ext/speex/gstspeexenc.c: (gst_speex_enc_encode): * ext/speex/gstspeexenc.h: Use integer encoding and decoding functions instead of converting the integer input to float in the element. The libspeex integer functions are doing this for us already or, if libspeex was compiled in integer mode, they're doing everything using integer arithmetics. Also saves some copying around.
