I attach two alternative patches (they built but I did not test them).

Both of them use two variants of _hurd_exception2signal and call the
non-default variant from trampoline.c when it's required. Non-exception
sigcodes are cleared to 0 in the legacy case, in both patches.

I personally favor "sigcodes_legacy_as_old.diff" since I believe we
should eventually phase out and get rid of the legacy sigcodes.
