Add check for to configure.in vsprintf, since HAVE_VSPRINTF is presumably
what was intended there.  Finally, also protected a bunch of if test
expressions with double quotes, as they were producing illegal test
commands.

Updated other codes as needed.

LDAP_SYSLOG in slap.h/slurp.h.

type 'sig_atomic_t' and marked it volatile.  Add detection to
configure to ensure sig_atomic_t and volatile are supported.

  -lldap_r can now be implemented...

including use of ctime_r, gethostby*_r, etc..  Also reworked ldap_sort_entries
to be reentrant.
Need to add code to properly set LDAP_API_FEATURE_THREAD_SAFE.

hosts_access depends on caller declaring some externs and, hence,
can be used for the test.

	Add plain -lpthread check.
	Move *_r() checks so that they are checked for regradless
		of thread libs used.  Before they were only being checked
		when using threads.
	Fix yields test such that compile/link/odd runtime failures results in
		'yes' instead of 'no'.

linking with $LTHREAD_LIBS.

Don't use new HAVE_FUNC_R on the client side (apps or libs).

Remove MD5 and SHA1 options (both are now always on).  Rename
functions to be lutil_ instead of ldap_.
Create --enable-cleartext option.  Default is currently 'on'.

to be used.  --without-subdir can be used to specify no subdirectory.

  default sysconfdir subdirectory is openldap instead of ldap.
    This removes conflicts with other ldap subsystems.  Should
    be configure option.
  *.conf files are now preserved.  A *.conf.default are always
    created with the latest conf.
  *.help and ldapfriendly are now placed in $(datadir)/$(ldap_subdir)
  updated man pages to reflect changes.

now that the mktime check is commented out.

the exact nature of the functionality being tested.  -DNO_THREADS
does NOT have a yield select, hence the macro is not defined.
The slapd/daemon code has been changed to test both no threads
and yielding select before using a timeout of NULL.

  Updated to use libtool 1.2 (with FreeBSD3.0 a.out v. elf detection).
  Updated autoconf to 1.12 with sed patch (don't use stock 1.12).
  aclocal.m4 is built using automake's aclocal, v1.3.
  Updated mkdep to support libtool .lo files.
Updated automake provided macros for TERMIOS, STRTOD, MKTIME, PTRDIFF_T
Autoconf now checks to ensure C compiler supports ANSI C prototypes.
Updated make files templates.

Sync portable.h.nt with portable.h.in

Add ac/bytes.h to provided sized types.
Use new sized type in md5/sha1 header through simple typedef.
Should substitute old type for new everywhere.

not to require knowledge of byte order such that this check can be removed.

Update NT port.
