subdirmk/regen.mk.in: Trim `$(srcdir)/' prefix from output makefile names

This doesn't make a difference if you're doing in-tree builds, of course.

subdirmk/generate: Supply default target if none given in command line

If you just run `make' then `$(MAKECMDGOALS)' is empty, so we get the
default target of `main.mk'.  Nothing is set up by `usual.mk', so we
end up with `$(srcdir)/configure' established by `regen.mk'.

Instead, propagate `all' to the `main.mk' makefile.  Maybe this should
be configurable, though I don't think that'll be very useful in real
life.

subdirmk/autogen.sh: Remove myself as copyright holder

I had nothing to do with this.  My original proof-of-concept suggested
that developers use `autoreconf' to bootstrap the working tree.

add copyright and licence notices to other files

In many cases I copied bits from mdw's originals, so they are all
potentially mdw's.
