[SVN commits to the Asterisk project]

Author: mmichelson

New Revision: 433170

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=433170
Log:
Switch to a NULL check for DNS answers from ast_strlen_zero.

Since the DNS answer is binary data, it's possible for it appear
to be a zero-length string. A NULL check is more appropriate.
