Summary:                    [patch] dsp.c sends multiple key presses up to
app_disa
Description: 
When using a mobile phone to dial in to a DISA system, digits are regularly
doubled and tripled up.

Using a landline with minimal interferance works nearly perfectly.

Changing the DTMF_MISSES_TO_END to more than 4, then prevents fast 50ms
DTMF rate, but still assist's with mobile phone DISA.

clean up section of dtmf_detect, saving on continuous writes every
iteration of this.
Only reset hits and misses on a DTMF EDGE.
