[PATCH] sigfix-2.5.39-A1

This fixes the bug reported by David Mosberger, force_sig_info() dropped
the siginfo structure, which broke things like SIGFPU or alignment-error
exceptions.  This bug was introduced by the threading signal changes.
(The patch also fixes signal declaration whitespaces in sched.h.)
