Review request for Asterisk Developers and Mark Michelson.


Summary
-------

ast_waitfordigit_full would simply pass its timeout to ast_waitfor_nandfds, expecting it to decrement the timeout by however many milliseconds were waited. This is a problem if it consistently waits less than 1ms, the timeout will never be decremented, and we wait... FOREVER!

This patch instead has ast_waitfordigit_full manage the timeout itself.


This addresses bug ASTERISK-20375.

Testing
-------

Mark confirmed that with the not-cleaned-up version of this patch, it fixed ASTERISK-20375. The cleanup consisted of changing variable names, adding comments, removing debug logging.


Thanks,

David
