This commit updates the handling of git checkouts from the database to use hardlinks if possible, speeding up this operation for large repositories significantly. As a refresher, Cargo caches git repositories in a few locations to speed up local usage of git repositories. Cargo has a "database" folder which is a bare checkout of any git repository Cargo has cached historically. This database folder contains effectively a bunch of databases for remote repos that are updated periodically. When actually building a crate Cargo will clone this database into a different location, the checkouts folder. Each rev we build (ever) is cached in the checkouts folder. This means that once a checkout directory is created it's frozen for all of time. This latter step is what this commit is optimizing. When checking out the database onto the local filesystem at a particular revision. Previously we were instructing libgit2 to fall back to a "git aware" transport which was exceedingly slow on some systems for filesystem-to-filesystem transfers. This optimization (we just forgot to turn it on in libgit2) is a longstanding one and should speed this up significantly! Closes #4604
