being renamed through modrdn/moddn. This in preparation to add support
for MODDN v3.

ignore input when connection is closing.

changes to closing.  Need to add protection against read set races.

Mainly updated back-bdb2, back-passwd, back-shell to use slap_get_time().

remove race conditions on connection close.
BROKEN: various counters for dn=monitor.
Initial testing on FreeBSD (with and without pthreads) was successfull.
Have not yet tested preemptive threading environments.
Have not built against backends other than LDBM.

by portable.h with NDEBUG undefined.  This makes assert() is always
available and automatically disables itself when LDAP_DEBUG is undefined.
I've included a basic assert() for pre-STDC compilers.  It relies on
abort() which may not actually be available.  (well replace abort()
with whatever is appropriate if and when we're faced with a pre-STDC
compiler that doesn't have assert()).

calloc(1, nelem*size) -> calloc(nelem, size)

address.  Useful for running multiple servers in a virtual hosting
environment.
Modified test001-ldif2ldbm to verify this functionality.  Assumes
localhost is 127.0.0.1.

SLAP_C_ACTIVE vs SLAP_C_INACTIVE.  Need to implement BINDING and CLOSING.
Added fields tracking pending (on bind) ops.  Could also be used to
implement per-connection thread limits.

They must not be deallocated since they are used by the cache entry.

using dc naming components with structural object classes that
don't allow a 'dc' attribute.

LDLINK -> LTLINK, LDAP_LIBEXECDIR -> libexecdir.  Add XSRCS and all-local-srv.

Replace LDAPMod with a new struct LDAPModList.
Rename lber_debug to lber_int_debug.

(First step towards full LDAPv2 support).

conn->c_protocol == LDAP_VERSION3;

lber: ifdef'ed out lber_..set_nonblock() function because it used ioctl's.
  If it remains, it needs to be written to support various methods for
  setting non-blocking.  ioctls should probably be last choice.  configure
  could detect existance of fcntl(), ioctl(), etc.
bdb2:
  added .dsp/.dsw files and did some basic cleanup (still needs work).

2. Make ldbm_Env a failure-safe entity.

LDAP v3 MODDN request.
