Largely simplify format handlers (for file copy etc.)
collecting common functions in a single place and removing them from the individual handlers. The full description is on mantis, http://bugs.digium.com/view.php?id=6375 and only the ogg_vorbis handler needs to be converted to the new structure. As a result of this change, format_au.c and format_pcm_alaw.c should go away (in a separate commit) as their functionality (trivial) has been merged in another file. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@17243 65c4cc65-6c06-0410-ace0-fbb531ad65f3
