Update slap_op to maintain dn and ndn (derived from conn->c_dn).
Update ldbm_back_bind to return actual bound dn (including rootdn)
for use in slapd_conn. Other backends use client dn.
Modify other codes to use ndn (normalized uppercase dn) most everywhere.
Aliasing, Suffixing and modrdn could use more work.
Applied suffixing to compare and modrdn.
Resolved deadlock by passing target entry to be_group and using
this if dn same as bdn. It might actually be safer to check
entry ids instead of dns.
Resolved bogus add to cache after failed acl check by deferring
cache add until after parent/acl checks have successful been
completed.
Eliminated race condition caused by concurrent adds
of same dn by adding 'li_add_mutex' around the critical section
of code (most of ldbm_back_add).
This code is preliminary and still needs significant testing.
Most function and variable definitions are now preceded by its extern
definition, for error checking. Retyped a number of functions, usually
to return void. Fixed a number of printf format errors.
API changes (in ldap/include):
Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.
A number of `extern' declarations are left (some added by protoize), to
be cleaned away later. Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.
adds POSIX RegEx (and removes BSD re_comp/re_exec) support.
* POSIX RegEx is not currently included in the distribution, however
we will probably add Henry Spencer's REGEX library soon.
* ACL Group functionality is also included in this merge!
