Summary: UTF-8-Sig codec

Initial Comment:
This patch implements a UTF-8-Sig codec. This codec
works like UTF-8 but adds a BOM on writing and skips
(at most) one BOM on reading.

OK, here's a text that explains what the BOM is used for in
various Unicode encodings. I hope that this can be turned
into something useful.

The place is right, but I feel this documentation is
incomplete still. The library reference should explain
somewhere what the difference between utf-8 and utf-8-sig
is. Perhaps a footnote could be added. I think I would
prefer a separate subsection on the BOM, explaining byte
order in UTF-{16,32}, and how the BOM can be used as a magic
signature for UTF-8.

This version (diff3.txt) of the patch adds a note to
Misc/NEWS and a section to Doc/lib/libcodecs.tex. Is this
the correct place to add the documentation?

The patch looks fine, but lacks documentation changes.

This second version of the patch will return starting bytes
immediately, if they don't look like a BOM.
