Patch to support to determine the number of args of the
gethostby{name,addr}_r functions.
Contributed by Juan Carlos Gomes IT#68 (apparently).

Also includes support for detecting ssleay in configure.in.

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.

	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

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.

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).

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.
