We'll put ldap_x_reference() functions in references.c

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.

interfaces are used.  Added comments to ldap_cdefs.h

implemented) logging requires LDAP_DEBUG_XXX levels always be defined.

ldap_set/get_option support for controls.

Remove ldap_get_lderrno().

at runtime.

from ldap.h to ldap-int.

Updated other codes as needed.

	struct friendly (Friendly) changed to ldap_friendly (LDAPFriendly)
	  ldap_friendly friend prefix changed to 'lf_' from 'f_'
	removed mod_next field from LDAPMod (struct ldapmod)
	modified slapd to use new LDAPModList (struct ldapmodlist) struct.
Added LDAPv3 result codes to ldap.h

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.

and ber_flatten() to the -llber.

	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'.

  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.

Clarify a few comments.

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.
