Re: (ITS#5436) htons() expects an unsigned short

Thanks.  Fixed os-ip.c in CVS HEAD (but see below).

short is signed by definition.

Do you have a test case?  As far as I can tell it broke if the caller
had the same error: storing a port number in a short, and passing that
short to ldap_init() & co.  And it broke on systems with 16-bit int, if
there are such system around where OpenLDAP compiles in the first place.

If we care about systems with 16-bit int, the proper fix is to also make
LDAPURLDesc.lud_port and various 'port' function parameters unsigned.  I
have no idea if there is such a system which can even compile OpenLDAP
though.
