Summary:                    Make transfer calls more pattern friendly
Description: 
Let these two patterns in a context:

_2XX => {
// do something
};

_X. => {
//do something else
};

If in a call between users in this context, we want to transfer the call
to a number like, eg, 210, then it match _X. pattern instead of _2XX. and
effectively tries to call extension '2'.

Tracing the code I found this may be because ast_app_dtget() looks for a
match on the dialplan in every key stroke.

This patch avoid this and only tries to transfer the call when a timeout
is reached (transferdigittimeout) or when the transferer party dials #.
