Alexander Leidinger 206b17d711 Commit the new (old) midi framework. It's based in parts on the NetBSD code,
but large parts are rewritten by matk and tanimura.

This is old code, it's not maintained since 2003. We also don't have a
maintainer for this! Yuriy Tsibizov took it and uses it in his emu10kx
driver. Since the emu10kx driver will enter the tree "soon" (some bugs
have to be fixed after Yuriy return from his holidays), I add it here
already.

This also contains some changes to emu10k1 and cmi, so if you're lucky,
you can now make some kind of use of midi with those soundcards.

To all those poor souls which don't have such a card: feel free to send
patches, we don't have a maintainer for this.

To those which miss a specific feature in the midi code: feel free to
submit patches, we don't have a maintainer for this.

Oh, did I already told that it would be nice if someone would take care
of it? Maintainer with midi equipment wanted! :-)

If you get LOR's, submit a PR and notify multimedia@ please. If you get
panics, submit a PR with a backtrace (compile the sound system into your
kernel instead of using modules in this case) and notify multimedia@
please.

Based upon:	code from NetBSD
