patch

Recent update of openladap-sasl-client changed the sendto(2) "tolen" argument
from:
sendto(..., dst, sizeof(sruct sockaddr));
to:
sendto(..., dst, sizeof(struct sockaddr_storage)); 

On FreeBSD with UDP sockets this change is invalid.

FreeBSD's getsockaddr() will copyin((dst, sa, len); and then set sa->sa_len =
len. With the above change sa_len will be 128.

Later in in_pcbconnect_setup() this socket address will be rejected with EINVAL
because sa_len != sizeof(struct sockaddr_in)

Patch openldap's liblber to always issue a the sendto(2) as follows:
sendto(..., dst, dst->sa_len);

This fixes both IPv4 and IPv6 sockaddrs in a manner compatible with the
kernel's getsockaddr() semantics.
