Ticket #599:

• Added "dec_fmtp" and "enc_fmtp" fields to pjmedia_codec_param.setting.
• Codec factory puts its default parameters in "dec_fmtp" field.
• pjmedia_stream_info_from_sdp() puts the "fmtp" attribute in SDP to pjmedia_codec_param.
• Special treatment for fmtp "bitrate" parameter (of G722.1) during SDP negotiation
• Added maxptime field in stream_info.
• Replaced iLBC's fmtp "mode" implementation to use general fmtp mechanism.
• Added some test scripts for G722.1 bitrate negotiation.
