PATCH: to implement toc and position shadowing in cdrom

Hi Eric,
Sorry to keep you on hold for so long. Here is my proposal for toc and
position shadowing that should address those performance and functional
issues we have already discussed and are summarized below. I've tested
it with cdplayer and it seems to be working pretty well now. To my
surprise and complete dismay it even worked the first time! It's ugly, I
know, but it should do it. I don't dare to delve into the BSD parts.
I'll leave these to a BSD expert.
Best,
Waldeck
Issues addressed by this patch
1. cdrom.c
1.1 Some systems/drives are very slow to read the TOC. To address this
issue, we are shadowing it inside the driver.
1.2 Windows will seek while not playing, Linux will not. We are
providing better compatibility with Windows by also shadowing the
current position.
2. mcicda.c
Windows will play data tracks as audio silently, Linux won't play at
all. With this patch we are simply avoiding playing data tracks. This is
important, otherwise CDs beginning with a data track will not start
playing unless you seek to the next audio track first. Since seeking to
the next track while stopped was impossible before the above patch to
cdrom.c, these disks would not play.
