add manual_rtp_bugs to profile and chan var and 3 new RTP bugs SEND_LINEAR_TIMESTAMPS|START_SEQ_AT_ZERO|NEVER_SEND_MARKER

	RTP_BUG_SEND_LINEAR_TIMESTAMPS = (1 << 3),

	  Our friends at Sonus get real mad when the timestamps are not in perfect sequence even during periods of silence.
	  With this flag, we will only increment the timestamp when write packets even if they are eons apart.

	RTP_BUG_START_SEQ_AT_ZERO = (1 << 4),

	  Our friends at Sonus also get real mad if the sequence number does not start at 0.
	  Typically, we set this to a random starting value for your saftey.
	  This is a security risk you take upon yourself when you enable this flag.

	RTP_BUG_NEVER_SEND_MARKER = (1 << 5),

	  Our friends at Sonus are on a roll, They also get easily dumbfounded by marker bits.
	  This flag will never send any. Sheesh....
