setup.exe rebase patch

[Jason Tishler <jason at tishler dot net>]

Attached is a patch that adds the rebase functionality to setup.exe.
I would like to get some feedback before I start to resolve the following
issues:

    o How to handle a missing config file (i.e., /etc/setup/rebase.conf)?
    o Need to handle in-use files.
    o How to handle corruptible (by rebasing) files?
    o How should dependent DLLs be handled?

and some other more niggling items.

I re-installed 30 out of the 33 packages that contain DLLs and my system
is functioning normally.  Python can even fork too!  I only skipped curl,
postgresql, and rxvt because the DLLs contained by these packages get
corrupted by rebasing.

If you would like to test out a setup.exe which includes the rebase
functionality, then a pre-built version is available at:

    http://www.tishler.net/jason/software/setup-rebase/setup-rebase-2002-02-02-1.exe

Before you run this setup.exe, you should download the default rebase
configuration file:

    http://www.tishler.net/jason/software/setup-rebase/rebase.conf

to /etc/setup.

I also have a stand-alone rebase.exe that I would like to contribute to
Cygwin so that users can rebase without having to run setup.exe.

Here is the current usage statement from rebase.exe:

    usage: rebase [-i|-r|-u] [-d CygwinRootDir] ImageFileName ...
    where:
        -i => install ImageFileName(s)
        -r => re-install ImageFileName(s) (default)
        -u => uninstall ImageFileName(s)
        -d => set Cygwin root directory (defaults to ".")

A pre-built version of rebase.exe is available at:

    http://www.tishler.net/jason/software/setup-rebase/rebase.exe

I see the following uses for this program:

    o makefiles
    o resync system (hopefully never needed)
    o used by a one-shot converter script

The following is an example of a postinstall script, rebase.bat, that
could rebase the entire user's system without have to reinstall
"everything":

    gzip -d -c /etc/setup/*.lst.gz | grep "\.dll$" | sed "s=^=/=" | xargs -n 1 cygpath -wa >rebase.tmp
    rebase -r -f rebase.tmp
    del rebase.tmp

The above assumes that I have added a "-f" option to rebase.exe and
changed the default value for the "-d" option to be the Cygwin root
directory obtained from the Registry.

Any feedback on the above would be greatly appreciated.

Thanks,
Jason
