Add support for auto-generating hardware notes entries in a
manner consistent with the new MI-style hardware notes document.

man2hwnotes.pl now defaults to generating entities for the MI-style
hardware notes (i.e. hardware/article.sgml). A new -c
option causes it to generate entities for the older MD-style
hardware notes (i.e. hardware/common/dev.sgml).

The Makefile infrastructure supplies the -c option to man2hwnotes.pl
now unless the HWNOTES_MI Makefile variable is defined, so
compatiblity is preserved for hardware notes translations that
aren't converted to the new organization yet. As translations
convert, they should define HWNOTES_MI in their hardware/Makefile.
When all the relevant translations catch up, the compatibility goop
in share/mk/doc.relnotes.mk and share/sgml/Makefile can be removed.

Thanks go to simon@ for help with the backwards compatiblity
mechanism.

Tested with: en_US.ISO8859-1, zh_CN.GB2312

- Add an -o option to specify the output file.
- Make "die()" more verbose.
- Do not put extra blank lines into the output file.
- Normalize text by using numeric entities because
some characters such as "'" can break the generated SGML.

Auto generate the device listings in the Hardware Notes based on
manual pages, to avoid duplicating work between the Hardware Notes and
manual pages.

Each text line in the output from the manual page parser is generated
as a SGML entity, making it possible for translators to only translate
lines which actually contains English text (this neat idea came from
hrs).

To determine which drivers are usable on which architectures the
dev.archlist.txt file is used to explicitly list this. It it an
imperfect solution, but the best I have been able to come up with for
now.

This commit converts most of the devices which has a section 4 manual
page with a HARDWARE section to be the new auto generated format.
