Fix rev 1.91 patch: Reset ltp_pending_count when flushing ltp_pending_list.
Remove flush_pending_list() again and the now-unnecessary 2nd call to it.
Help the compiler a little.
Move ltp_work_list in case it makes a difference for caching.
Move mutex unlock in pool_destroy() to make concurrency debuggers happier.
Replace ltp_state with ltp_finishing. Drop state
LDAP_INT_THREAD_POOL_STOPPING, flush pending list instead.
ltp_max_pending = default value instead of 0, and negative when finishing.
Add ldap_pvt_thread_pool_pausing(): pause check for slapd without locking.
Make counters int instead of long; INT_MAX pending tasks is enough.
Nitpick cleanup: goto failure instead of if() to not-failure in _submit().

Not needed after ldap_int_thread_userctx_t.ltu_id was added and
_pool_wrapper took care not to update thread_keys[] during pauses.
Fix bogus thread_keys[].ctx comment.
- Move problematic mutex_unlock()-mutex_lock() into the unused #ifdef
LDAP_PVT_THREAD_POOL_SEM_LOAD_CONTROL and add a FIXME comment inside.
- Delay ltp_starting--; until pool_wrapper(). Nonzero value could otherwise
no longer be exposed when !defined LDAP_PVT_THREAD_POOL_SEM_LOAD_CONTROL.
