configure checks for getpwuid(), sys/resource.h, and pwd.h
	Fix !TERMIOS && !SGTTY ifdef in ud/util.c

Update NT portable.h and features.h

to force no prototypes or require them.
Remove _WIN32 clause.  Will update portable.h.nt to define __NEED_PROTOTYPES.

Fix pointer truncation to int by including prototypes in forward declarations.

inet_addr() on OSF1 returns (unsigned int)0xffffffff, not int.
If it had returned int, the old code would have worked.

It returns (int)0xffffffff on OSF1 which has 64-bit long, so
`unsigned long address; ... if((address = inet_addr(str)) == -1)' fails.

 #include <stdlib.h>    to get malloc & co various places,
 #include <ac/string.h> to get strlen & co in (liblutil/setproctitle.c),
 declare ch_malloc & co (slurp.h), avl_find_lin (avl.h), Malloc (ud/edit.c).
Also changed ch_malloc & co from char* to void* functions.

Locks were not always released, in particular if something went wrong.
Fixed in slurpd and the slapd main dir.  Slapd clients were not examined.
It also "felt right" to swap the order of closing dfp and rfp in slurpd
copy_replog(), so the last acquired lock is unlocked first.

has been included.

-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.

Modified clients to reduce use of ldapconfig.h.edit.
ldap_{get,set}_option support is relatively complete.  Needs
to be extended to support other "features" of OpenLDAP.

Fix old -pthread -lmach ... support to check for -lc_r instead of -lc.

  ifndef HAVE_PTHREAD_KILL pthread_kill() code and prototype.
  Fix HAVE_FUNC_PTHREAD defines from previous change.

Fix pthread_attr_init/destroy pthread draft4 compatibility.

  configure generates ldap_features.h based from ldap_features.h.in
  LDAP_REFERRALS -> LDAP_API_FEATURE_OPENLDAP_V2_REFERRALS
  LDAP_DNS -> LDAP_API_FEATURE_OPENLDAP_V2_DNS

Add openldap_ldap_initialize() call to ldap_init/ldap_open/ldap_get/set_options.

Updated portable.h.nt based upon portable.h.in (1.11).

initialize_client() should return void.  Fix and forward declaration.
