Start revamping `autoconf --trace'.

* autoconf.sh (debug): New var, new option.
Adjust the trap code.
(task trace): Instead of decoding `m4 --trace' with sed, decode it
with m4 itself.
($silent_m4): New file, which disables m4's `errprint'.
($trace_m4): New file.  Logistic for the m4 which is in charge of
decoding the traces of the first.
($translate_awk): Transform a user trace request into $trace_m4
code.
