I was initially thinking that the extracted function would be used by the ConfBridge playback_and_continue DTMF hook to wait for digits if a digit did not interrupt playback but it does not. The playback_and_continue just exits the menu instead.</pre>

That DTMF hook needs a flag to say not to clear the collected digits buffer before calling.
ast_bridge_dtmf_hook() needs to be able to pass this do not clear digit collection buffer before calling hook flag.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This is the Asterisk 13 version of the following: https://reviewboard.asterisk.org/r/4477/
Attempting to execute DTMF in a confbridge while file playback (prompt, announcement, etc) is occurring is not allowed. You have to wait until the sound file has completed before entering DTMF. This patch fixes it so that app_confbridge now monitors for dtmf key presses during file playback. If a key is pressed playback stops and it executes the matched menu option. Unlike the Asterisk 11 patch this version does not re-queue the dtmf frame, but instead uses an already available function that monitors for dtmf presses during playback.</pre>

Setup a basic conference bridge that allowed both regular and admin users to enter. Ran through various menu options to make sure the sound file playback would stop (no longer have to wait) and a new option was executed when appropriate. Also ran the app_confbridge testsuite tests to make sure they still passed.</pre>
