Add target directory to checkout
This adds the ability for checkout to write to a target directory
instead of having to use the working directory of the repository.
This makes it easier to do exports of repository data and the like.
This is similar to, but not quite the same as, the --prefix option
to `git checkout-index` (this will always be treated as a directory
name, not just as a simple text prefix).
As part of this, the workdir iterator was extended to take the
path to the working directory as a parameter and fallback on the
git_repository_workdir result only if it's not specified.
Fixes #1332
