When removing the last value from an attribute in ldap_del_values()
the actuall attribute needs to removed instead of leaving back an
empty attribute. Empty attributes are not valid and fail later on
in ldap_modify(). By calling ldap_del_attribute() in this case
properly removes the attribute and with that validate_entry() no
longer fails later on.

The ber_* namespace is used by liblber since time immemorial,
so move our BER API to the unused ober_* prefix to avoid some
breakage in ports.

Problem diagnosed by jmatthew with ber_free() in samba, but
there are many others as pointed out by sthen.

branches: 1.5.12;
Correct handling of requests to delete individual attribute values.

reported by ZHANG Huangbin (zhb (at) iredmail.org)
fix by Robert Klein (roklein (at) roklein.de)

work on making log.c similar in all daemons:

move daemon-local functions into new logmsg.c, and reduce
the (mostly whitespace) differences so that log.c's can be diffed easily.

ok krw@ jmatthew@

Fix a segmentation fault when adding an attribute to an empty entry.

Avoid double free in ldap modify requests. The values received in the
modify request is linked into the stored ber structure, and then both are
freed. Fix this by unlinking the values from the request.

Initial import of ldapd, a small LDAP daemon. Work in progress.
