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.

avoid passing NULL to asprintf(3) when there's no parent dn entry
OK jca@

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@

bzero -> memset. No binary change.

Do not assume that asprintf() clears the pointer on failure, which
is non-portable. Also add missing asprintf() return value checks.
OK deraadt@ guenther@ doug@

Unbreak re-indexing by checking if an index entry already exists.

Unbreak removal of one-level search index.

Set errno to appropriate values when returning failure in btree. Make btree
functions only return success or failure (-1 or NULL). Update callers to
check errno.

Remove compaction and indexing from ldapd. It is better done by a separate
process now that the btree can pick up the changes automatically.

Track changes in btree_txn_* API, pass a NULL btree when also passing a
transaction.

Fix compilation on gcc2. Check a return value from malloc while at it.

"that compiles!" deraadt@

Remove trailing whitespace and spaces before tabs.

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