Message:

Ticket #923: New API to retrieve current jitter buffer state from a stream/session

• added pjmedia_session_get_stream_stat_jbuf() and pjmedia_session_get_stream_stat_jbuf()
• fixed const correctness in pjmedia_jbuf_get_state(), jb_framelist_size(), and pj_math_stat_get_stddev(),
• modify the jitter buffer statistic log message printed by stream (it contains newlines)

• pjproject/trunk/pjmedia/src/pjmedia/stream.c (modified) (5 diffs)
