perl 5.003_06: utils/h2xs.PL

Subject: h2xs bug fix

The h2xs that is in perl5.003_05 has a regexp bug which prevents it from
finding #define statements and filling the constant() function.  This patch
fixes that.  The h2xs_test program found this--maybe people who are
modifying h2xs should get a copy of the test program.

This also adds a -d to enable debugging messages (there's just one for now).
I've also placed some of the doc-related things in alphabetical order.

h2xs_test can be found in my directory on CPAN.  Those of you modifying
xsubpp should know there's a test suite for that, too, called XSTEST which
can also be found in my directory on CPAN.
