Summary:                    Fast RFC2833 dialing results in asterisk generating
overlapping
Description: 
Scenario: call established between 2 rfc2833 endpoints but no packet 2
packet bridge.

If the calling party sends digits really fast (less than the min gap of 45
milliseconds).  Asterisk will attempt to slow down the dialing through dtmf
emulation.  

When this occurs, it is possible that the next digit arrives while the
previous digit is still being emulated by asterisk.  Currently asterisk
doesn't check to see if a dtmf is currently being emulating before
forwarding the start frame of the next dtmf.

This patch adds a check so that if the previous digit is still being
played the start frame will not be forwarded (the end frame will be
enqueued for emulation).

Ensure that emulated DTMFs do not get interrupted by another begin frame.
