New Revision: 430567

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=430567
Log:
app_macro: Don't restore the calling location on a channel redirect.

v11: If a channel redirect to a macro exten of a macro that is active
happens, the redirect location doesn't get executed.  Instead the original
macro location is restored and gets reexecuted.

v13: An additional effect happens if a parked call times out to an
extension in the macro that parked the call then the macro is reexecuted
instead of the expected park return location.

* Made not restore the macro calling location on an
AST_SOFTHANGUP_ASYNCGOTO.

* Increased the locked channel range when setting up the macro execution
environment to cover things that should be done while the channel is
locked.

* Removed unnecessary NULL tests before calling ast_free() in
_macro_exec().
