Most thread implementations suppport a native recursive mutex, use that
where possible (especially when a regular mutex is recursive already).
Also provide a macro for applications to test whether they can use the
lock functions interchangeably.
Expand usage struct with magic numbers and state info.
Add options "noreinit", "nosync", "nomem", "threadID". Remove "dupinit".
Detect address changes. Turn off thread ID tracking by default.
enabled with LDAP_THREAD_DEBUG (cpp macro and environment variable):
Move any ldap_pvt_* definitions from ldap_int_thread.h to ldap_pvt_thread.h.
#define ldap_int_thread_equal/ldap_pvt_thread_equal instead of tpool.c:TID_EQ.
Define some ldap_debug_*_t types, and LDAP_UINTPTR_T, in ldap_int_thread.h.
ldap_int_thread.h/ldap_pvt_thread.h can now be included multiple times, giving
different results depending on whether libldap_r/ldap_thr_debug.h was included.
Add some cleanup and some preprocessor hacks.
#define LDAP_THREAD*_IMPLEMENTATION in libldap_r/*.c, used by ldap_thr_debug.h.
Add PTHREAD_MUTEX_ERRORCHECK/PTHREAD_MUTEX_ERRORCHECK_NP in thr_posix.c.

macros into our namespace and limit use to headers. A subsequent
round will add macros to separately handle forward declarations
of variables from declaration of function prototypes. The last
round will add additional macros for declaring actual variables and
functions.
r/w locks and thread pools. Hide internal structures (using
pthread'ish technics). Place common code in threads.c. Move
no-thread code to thr_stub.c. Move thread pool code to tpool.c.
Removed setconcurrency call from initializer, added 'concurrency'
directive to slapd. Tested code under pthreads, pth, and no-threads.
