windows-tls: Implement TLS key destructors for native Windows.
* lib/windows-tls.h (glwthread_tls_process_destructors): New
declaration.
(GLWTHREAD_DESTRUCTOR_ITERATIONS): New macro.
* lib/windows-tls.c: Include <limits.h>, windows-once.h.
(dtor_table_init_once, dtor_table_lock: New variables.
(struct dtor): New type.
(dtor_table, dtors_count, dtors_used, dtors_allocated,
dtor_processing_threads): New variables.
(dtor_table_initialize, dtor_table_ensure_initialized,
dtor_table_shrink_used, glwthread_tls_process_destructors): New
functions.
(glwthread_tls_key_create, glwthread_tls_key_delete): Rewritten to
handle non-NULL destructors.
* modules/windows-tls (Depends-on): Add windows-once.
* lib/glthread/tls.h (glthread_tls_key_init, glthread_tls_key_destroy):
Use the functions declared in windows-tls.h.
* lib/threads.in.h (TSS_DTOR_ITERATIONS): Define using
GLWTHREAD_DESTRUCTOR_ITERATIONS.
* lib/windows-thread.c: Include windows-tls.h.
(wrapper_func, glwthread_thread_exit): Invoke
glwthread_tls_process_destructors.
* modules/windows-thread (Depends-on): Add windows-tls.
