kernel: trap-dependent state restore, trace fixes
. restore state depends on how saving of state was done;
also remember trap style in sig context
. actually set and restore TRACEBIT with new trap styles;
have to remove it once process enters kernel though, done
in debug trap exception handler
. introduce MF_STEP that makes arch-specific code
turn on trace bit instead of setting TRACEBIT directly,
a bit more arch-friendly and avoids keeping precious
state in per-process PSW arch-dependently
