Error in comments for apr_sockaddr_info_get in apr_network_io.h

[Joshua Moore-Oliva <jo...@chatgris.com>]

The document reads.

@param hostname The hostname or numeric address string to resolve/parse, or
 *               NULL to build an address that corresponds to 0.0.0.0 or ::

However, it only works if I pass APR_ANYADDR which makes sense since it's 
defined as 0.0.0.0
