New Revision: 355620

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=355620
Log:
Fix compile problem when old version of libvorbisfile v1.1.2 is used.

The principle difference between libvorbisfile v1.1.2 and newer (at least
v1.2.0) is the addition of the predefined callbacks OV_CALLBACKS_xxx in
vorbis/vorbisfile.h used for ov_open_callbacks().

* Updated the configure script to detect if libvorbisfile.h declares
OV_CALLBACKS_NOCLOSE.

* Copied the declaration of OV_CALLBACKS_NOCLOSE from v1.2.0 to allow
v1.1.2 to compile.

(closes issue ASTERISK-19370)
