* scmsigs.h (scm_sigaction_for_thread): New prototype.
* scmsigs.c (got_signal): Removed.
(signal_handler_cells, signal_handler_threads): New.
(take_signal): Queue the cell of the signal for the specified
thread. Reset the signal handler on systems that don't have
sigaction.
(sys_deliver_signals): Removed.
(close_1): New.
(scm_sigaction_for_thread): Renamed from scm_sigaction and
extended to also set the thread of a signal and allocate a cell
for it. Keep the Scheme name "sigaction". Check that signum is
within range. Also, use SCM_VECTOR_REF instead of SCM_VELTS.
(scm_sigaction): Implement in terms of scm_sigaction_for_thread.
(scm_init_scmsigs): Allocate signal_handler_cells and
signal_handler_threads vectors.
* async.c: Removed GUILE_OLD_ASYNC_CLICK code. Reorganized so
that system asnycs and user asyncs are separated. Reimplemented
system asyncs to work per-thread.
* gc.c (scm_init_gc): Do not use scm_system_async.
* async.h (scm_asyncs_pending, scm_set_tick_rate,
scm_set_switch_rate, scm_system_async_mark_from_signal_handler):
Removed prototypes.
(scm_i_queue_async_cell): New.
* __scm.h (scm_asyncs_pending_p): Removed.
(SCM_ASYNC_CLICK): Check scm_active_asyncs instead of
scm_asyncs_pending_p.
* async.h (scm_system_async_mark_for_thread): New prototype.
* __scm.h: Removed GUILE_OLD_ASYNC_CLICK code.
* root.h (scm_root_state): Added new "active_asyncs" slot.
* root.c (scm_make_root): Initialize it to SCM_EOL.
* coop-defs.h (coop_t): Added new "handle" slot.
* coop-threads.c (all_threads, scm_current_thread,
scm_all_threads, scm_i_thread_root): New.
(scm_threads_init): Add main thread to all_threads.
(scheme_launch_thread): Remove thread from all_threads when it
terminates.
(scm_call_with_new_thread): Initialize handle slot of coop_t
structure and add new thread to all_threads.
(scm_spawn_thread): Likewise.
* threads.h (scm_current_thread, scm_all_threads): New prototypes.
* threads.c (scm_current_thread, scm_all_threads): Register as
primitives.
* dynl.c: Use scm_lt_ prefix for libltdl functions.

* script.c (scm_compile_shell_switches): Fix bad spelling of
