Adds immediate yes/no option to iax.conf

This is very similar to the DAHDI immediate=yes option.  When the phone is picked up, instead of giving a dialtone it connects directly to the "s" extension.  Changes where implemented in chan_iax2.c to directly connect to the "s" extension in the appropriate context when this option is enabled.  Examples explaining its use are added to iax2.conf.sample.  CHANGES has been updated as well.
