/*
 * Support for thr_debug.c:
 *
 * thr_debug.c defines ldap_pvt_thread_* as wrappers around the real
 * ldap_pvt_thread_* implementation, which this file renames to
 * ldap_int_thread_*.
 *
 * Implementation:
 *
 * This file re#defines selected ldap_pvt_thread_* names to
 * ldap_int_thread_*, which will be used from wrappers in thr_debug.c.
 * Two ldap_int_*() calls are redirected to call ldap_debug_*(): These
 * are wrappers around the originals, whose definitions are not renamed.
 * This file then #includes ldap_pvt_thread.h to declare the renamed
 * functions/types.  If #included from thr_debug.c it finally #undefines
 * the macros again.
 *
 * include/ldap_pvt_thread.h declares the typedefs ldap_pvt_thread*_t as
 * either wrapper types ldap_debug_thread*_t or their usual definitions
 * ldap_int_thread*_t, depending on the LDAP_THREAD_DEBUG_WRAP option.
 * When defining the underlying implementation, this file then redirects
 * the type names back to the original ldap_int_thread*_t types.
 * include/ldap_<int,pvt>_thread.h also do some thr_debug magic.
 *
 * So,
 * libldap_r/<not thr_debug.c> thus define ldap_int_thread_*() instead
 * of ldap_pvt_thread_*().
 * thr_debug.c defines the ldap_pvt_*() and ldap_debug_*() functions.
 * In thread.c, ldap_pvt_thread_<initialize/destroy>() will call
 * ldap_debug_thread_*() instead of ldap_int_thread_*().
 * In tpool.c, ldap_int_thread_pool_shutdown() has explicit thr_debug.c
 * support which treats ldap_pvt_thread_pool_destroy() the same way.
