Added OpenLDAP copyright to files.

Fixed my own stupid mistake of not noticing the 'n' in #ifndef. strdup
should work as it was again...

Fixed a small typo...

return cache entry.

Changes to support threads from libldap_r.

Updates regarding threads and names.

Updates for the new threading and utility stuff in libldap{_r}.

Fixed a small but nasty typo.

environment settings.

might have in their ldap.conf(5) file.

strpbrk was checked for twice, and something didn't work. Now it does.

Improved ldap_int_strtok. If strtok_r does not exists, it will be worked
simulated with strspn and strpbrk. If strspn or strpbrk aren't there, they
will be supplied.
In addition, the memory-handling of the ldap_int_gethostby's is better now.

John's still working on the 'perl-test' (the perl backend test module).

will eventually be very last).  Add lthread/lutil to libldap_r test
program linkage.

end of link.    Basic order is:
	$LDFLAGS internal-libs external-libs $LIBS $LTHREAD_LIBS

LTHREAD_LIBS is last as -lpthread (or equiv) must be last on many systems.
LIBS is next to last as some user might have put -lpthread (or equiv)
in $LIBS.

Might as well keep link order consistent between -devel and 1.1

creation codes to provide this field.  Update cache_entrydn_cmp
to strcasecmp() the e_ndn instead of e_dn.  Note: strcasecmp()
is still used as e_ndn isn't in uppercase.  Maybe it should
be.  Did not update other codes to use e_ndn.  Hence, there
are lots of dn_normalize() calls that could be eliminated.
(The case determination of e_ndn should be made first).

in -lbind then in -lresolv.

Probably should detail each of these items with an ITS...

creating them detached.  This hopefully will reduce problems on
draft4 pthread implementations related to creating detached
threads (which is _np under draft4) on some platforms without
causing problems with other thread implementations.

of a busy wait and allow the pthread_yield within the loop to be
removed.  This was the only pthread_yield which was necessary
when usng non-preemptive threads.  As such, the configure.in
sched_yield/pthread_yield missing error can be removed from
configure.in.  If explicit yield function is missing, just provide
a no-op replacement.
Moved declaration of various slapd globals from main.c to init.c
so they can be shared with ldbm tools.

  make depend, make tests, and make install all work when build directory
  is not the $srcdir.
Also modified library handling such that -lpthread more likely to be last.
WARNING: new orderring requires use of LDFLAGS to set global loader options
  such as -L/usr/local/lib.  If you put this in LIBS, some libraries
  may not be found a link time.
Likely broke Kerberos/LDAPD support.  Don't have those in my testbed.

rename 'struct conn' to 'struct slap_conn'
rename op_function to slap_op_func for functions add/delete/free
This change is need to avoid clashing with perl internals.
