I really need to dig deeper here, some libpri events never fire for
incoming calls and i'll have to find out how mod_freetdm or the
FreeSWITCH core change states on the channel...

Anyway, incoming and outgoing calls still work for me (BRI PTMP TE),
so commit this now and let a wider audience do some more testing.

ftmod_pritap: Abort before overflowing spanparameters array and initialize to all zero
ftmod_isdn:   Fix overflow check, skip over parameters without name or value, initialize spanparameters array to all zero.
ftmod_libpri: Skip over parameters without name or value, initialize spanparameters array to all zero and drop "i < 10" hardcoded check.

This should fix:

"if (ftdm_array_len(spanparameters) == paramindex)" is still off-by-one,
we want to stop at "ftdm_array_len(spanparameters) - 1", before we overwrite
the last (= terminating, NULL) element.

NOTE: i'd prefer an "argc, argv"-style interface here

mod_freetdm: Avoid overflowing the spanparameters array of libpri spans, and make other span types use ftdm_array_len() too.

Move some things around and remove 'paramindex' var (just use 'i' for that too).

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....
