contrib/workdir: add a simple script to create a working directory
Add a simple script to create a working directory that uses symlinks
to point at an exisiting repository. This allows having different
branches in different working directories but all from the same
repository.
Based on a description from Junio of how he creates multiple working
directories[1]. With the following caveat:
"This risks confusion for an uninitiated if you update a ref that
is checked out in another working tree, but modulo that caveat
it works reasonably well."
