Similar method to latest spandsp/dtmf.c
We must detect 2 silences for DTMF END.
Reverts some of 111022 that added DTMF_HITS_TO_BEGIN and DTMF_MISSES_TO_END
Exisiting dtmf events with;
/* hits_to_begin = 3, misses to end = 2 */
/* --------A hits=1, misses=1, lasthit='A'
* -------AA hits=2
* ------AAA hits=3, store_digit, current_hit='A', BEGIN A
* -----AAA- hits=1, misses=1, lasthit=' '
* ----AAA-- misses=2, current_hit=' ', END A
* ---AAA--B hits=1, misses=1, lasthit='B'
* --AAA--BB hits=2
* -AAA--BBB hits=3, store_digit, current_hit='B', BEGIN B
* AAA--BBB- hits=1, misses=1, lasthit=' '
* AA--BBB-B hits=1, misses=1, lasthit='B'
* A--BBB-BB digitlen += GSIZE
* deal with an interruption
* --BBB-BB- hits=1, misses=1, lasthit=' '
* -BBB-BB-B hits=1, misses=1, lasthit='B'
* BBB-BB-BB digitlen += GSIZE
* deal with no interdigit pause
* BB-BB-BBC hits=1, misses=1, lasthit='C'
* B-BB-BBCC current_hit=' ', END B
* -BB-BBCCC hits=2
* BB-BBCCCC hits=3, store_digit, current_hit='C', BEGIN C
*/
How it would be without, hits_to_begin, and misses_to_end
/* ------AA Begin A
* -----AA- no change
* ----AA-- End A
* ---AA--B no change
* --AA--BC no change
* -AA--BCC Start C
* AA--BCCD no change
* A--BCCDD Start D
* --BCCDD- no change
* -BCCDD-E no change
* BCCDD-EE Start E
* CCDD-EE- no change
* CDD-EE-F no change
* DD-EE-F- no change
* D-EE-F-- End E
