FYI: java.util merge

[Tom Tromey <tromey at redhat dot com>]

I've now merged java.util.* between libgcj and Classpath.

In many cases I found the Classpath implementation to be superior in
some respect.  In other cases I've kept specific pieces of the libgcj
implementation (e.g. where a bug was present or where synchronization
was required).  In some cases the code was identical; I merged these
too on the theory that merging is helpful even for trivial classes
(there might be a bug or a change to the spec in the future; merging
makes it simpler to do less work).

I didn't merge java.util.zip, since the libgcj implementation heavily
relies on native code.

Look in the Classpath and (soon -- the patch isn't in yet) the libgcj
ChangeLogs for the details.

I wrote a simple little script which generates an HTML report
comparing the libgcj and Classpath trees.  I can send it to anybody
who is interested.  You need both trees checked out for it to work.
