changes.

Building tests/progs/*.c in the main build process.
==> Test-suite must be called by 'make test', or 'make test-bdb2'

Still requires user to workaround Solaris pthread_create in -lc issue.

Implementation no longer uses strtok_r(), it may be broken
or have an odd prototype.
Update configure not to check for strtok/strtok_r nor require
strtok_r to LDAP_API_FEATURE_X_OPENLDAP_REENTRANT.

instead of AC_CHECK_FUNCS() as symbol may be mangled.

Integration into ./configure ( --enable-bdb2 ).
Adaptation of the test-suite ( 'make' -> ldbm; 'make bdb2-local' -> bdb2 ).
Minor fixes in slapd/libldbm.

	Kerberos detection of des_debug
	detection of resolv.h and arpa/nameserv.h
Updated affected codes.

Update acconfig.h to use @TOP@ and @BOTTOM@ to rid ourselves of
the .top/.bot files.

Added comment with order of checks.

Supports 'yes', 'no' (default), and 'auto'.

Fix LDAP_API_VENDOR_VERSION -> LDAP_VENDOR_VERSION bug

AC_CYGWIN AC_MINGW32 AC_EXEEXT AC_OBJEXT

	Likely broke things for non-posix threadings....

Update -lldap_r implementation to:
	remove attribute support
	hide thread detachment
	provide concurrency accessors
	provide initialization function
	fix gethostby{addr,name}_r codes (not coverred by HAVE_REENTRANT_FUNCTIONS)
Update servers/libraries to use ldap_pvt_thread_ calls.
Cleanup server codes (no #ifdef HAVE_PTHREAD_THIS or _THATs)!
Removed -llthread

	back-ldbm was using a cache specific lock to protect non-reentrant
	database routines from being reenterred.  This is inadequate.
	Also, reentrant database systems calls were serialized unnecessarily.

	Non-reentrant database calls must have a big_mutex.  Implemented
	this within -lldbm itself.  library requires ldbm_initialize()
	be called before any other ldbm call to initialize the big_mutex
	and to do any other db specific initialization (ie: such as
	required for DB2).

The dbc_mutex, dbc_cv, & dbc_readers fileds of dbcache are history.
The "reentrant_database" (REENTRANT_DATABASE) define is also axed.

Rewrite all child waits to use wait4 (for consistency only).

libldap/string.c will hold various string.h replacements.
Removed liblutil/strdup.c
Moved ldap_pvt_strtok to string.c.
Moved prototype of ldap_pvt_strtok to <ac/string.h>.
Added #define strtok_r ldap_pvt_strtok (if strtok_r doesn't exist).

Suggest --with-threads=posix when error is reported.

Once we have private types for threads, this check can be removed.

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

in -lbind then in -lresolv.

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.

one preprocessor macro instead of two.  Ran aclocal, autoconf,
autoheader to update derived files.  Modify util-int.c to use
CTIME_R_NARGS define and fallback to ctime() if not set.
Made LDAP_API_FEATURE_X_OPENLDAP_REENTRANT dependent upon result.
