Coverted LDAP_LOG macro to use subsystem ID int values instead of string values

  must include <ac/stdlib.h> to get MAX_PATH defined.
  use LDAP_DIRSEP instead of '/' in paths
  define truncate/ftruncate macros, etc.

Added LDAP_LOG Messages

get read until much later, too late for TLS_RANDFILE to be useful.

for slurpd's replica directory (slurpd.status, and rej file) use a subdir of what the user specifies (add replica/ to it) to avoid /tmp races. A lot of the files that slurpd uses cannot be opened with O_EXCL, nor can we safely determine if there are any hardlinks from another file to it, so we create our own subdirectory so we can control the perms, even in /tmp

Replace old Id as needed (back-tcl).
Leave updating of contribWare to contributors (for now).

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

Move all SunOS routines (ie: _sleep() and its helpers) to thr_lwp.c
so that it's internals can be 'static'.  Add 'static' to thr_lwp.c.
Add comment to LWP:  NEEDS WORK, may not compile!  Need some
SunOS user to sort out the details.  Volunteers?

	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

Seems that calling pthread_exit() in the main (and only active)
thread does not cause the whole process to exit.  Very odd.
Anyways, as we want to whole process to exit, we should just exit
after joining with our other threads.
I've also removed dead code for detaching threads we join with.

Most function and variable definitions are now preceded by its extern
definition, for error checking.  Retyped a number of functions, usually
to return void.  Fixed a number of printf format errors.

API changes (in ldap/include):
  Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
  for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.

A number of `extern' declarations are left (some added by protoize), to
be cleaned away later.  Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.

-thread & -pthread are still treated as libraries, will need
additional work to use them as CFLAGS.
Eliminated HAVE_DCE define (was redundant) and its use.  Code
now relies on draft4 and function existance tests.

in string.h was hosed for memmove/memcpy cases.

Need to sort out remaining ifnames and run testsuite.
