Calling a gosub routine defined in AEL from Dial/Queue ceased to work.

Browse Source 
A bug in AEL did not distinguish between the "s" extension generated by
AEL and an "s" extension that was required to exist by the chan_dahdi
(or another channel) that was not supplied with a starting extension.
Therefore, AEL made incorrect assumptions about what commands were
permissable in the context.  This was fixed by making AEL generate a
different extension name.  However, Dial and Queue make additional
assumptions about the name of the default gosub extension.  Therefore,
they needed to be brought into line with a "macro" rendered by AEL (as
a gosub), without breaking traditional dialplans written without the
aid of AEL.
