Summary:                    [patch] Rogue Newchannel events for failed Originate
calls
Description: 
When using AMI Originate to unavailable device, there's NewChannel event
without following Hangup event. 

I traced this to ast_pbx_outgoing_cdr_failed() which creates new channel
for CDR posting purposes, however destroys without ast_hangup() sending
Hangup event. It could probably be fixed by replacing ast_channell_free()
with ast_hangup(), however in SVN trunk there's function for allocating
dummy channel instead. 

Attached patch that won't generate events for channels with empty names
(this is probably why there was check for empty name_fmt, however it's
impossible to call ast_channel_alloc with empty name_fmt.

Affected 1.6.1 and 1.6.2 and probably below. SVN trunk uses dummy channel,
so probably unaffected.

Last patch works great on our production system since I posted.

However other occurrences probably need some attention
