s4-lib/tls: Try socket_send() multiple times to send partial packets
This works around an artificial limitation in socket_wrapper that breaks
some versions of GnuTLS when we return a short write.
Instead, keep pushing until the OS will not take it.
The correct solution will be to use tls_tstream, but the client code
for this is not yet tested and needs the ldap client layer changed
to use it.
