New Revision: 357005

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=357005
Log:
Convert netsock.h over to use ast_sockaddrs rather than sockaddr_in and update
chan_iax2 to pass in the correct types.

chan_iax2 is the only consumer for the various ast_netsock_* functions in trunk
at this point, so this feels like a safe change to make.
