* 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.
