I like this.  Anything that makes working out which patches have been
merged and removing them easier gets a big smile from me.  I'm also
strongly in favour of organising the patches directory a bit better,
especially if it makes it clearer which stuff is going to end up in
OpenJDK6 eventually and which stuff we'll be maintaining for life.

b77 is already out, so I just need to get round to updating IcedTea7
to build against it, dropping the ia64 patch and part of the uname
patch (the rest I'll stick in a Debian subdir as it's specific to that
platform).
I hope b78 will see a HotSpot promotion and IcedTea7 will be clear of
zero patches for the new year.
