for building backends as modules.

create SECURITY_LIBS (top.mk) to order $SASL_LIBS $KRB_LIBS $TLS_LIBS
use $SECURITY_LIBS in Makefile.in's instead of $KRB_LIBS $TLS_LIBS

s/exit(0)/exit(EXIT_SUCCESS)/
add <ac/stdlib.h> where needed and other minor header adjustments

Requires FreeBSD's -lfetch...
Implementations to other URL APIs encouraged.
Probably should be moved to -llutil.

subdirectories; add explicit dependencies for subdirs that need them.

Rework sys_errlist detection to set HAVE_SYS_ERRLIST if sys_errlist
exists.  If it declaration is needed, DECL_SYS_ERRLIST is also set.

of explicit acconfig.h entries.

Includes support for update referral for each replicated backend.
	Reworked replication test to use update referral.
Includes major rewrite of response encoding codes (result.c).
Includes reworked alias support and eliminates old suffix alias codes
(can be emulated using named alias).
Includes (untested) support for the Manage DSA IT control.
Works in LDAPv2 world.  Still testing in LDAPv3 world.
Added default referral (test009) test.

Fix detection of socklen_t
Rebuild configure to reflect that

Pass TLS_LIBS to the Makefile's.

getspnam() is used instead of getpwnam() when available.
Added configration detection of pw_passwd, shadow.h, getpwnam()
and getspnam().

backout previous nt changes (actually, just don't include nt_svc.c)

"compiler" and "flags" has changed.
    Pre-configure:
        env MKDEP=mycc MKDEP_FLAGS=myccflags ./configure
    Post-configure:
        hack top.mk and run ./config.status
