From: Alex Kiernan <alex.kier...@gmail.com> Since disable network was added cargo configurations which reference git repos fail as they attempt to fetch across the network as part of do_compile, even if EXTRA_OECARGO_PATHS to add them as part of `paths` is used, as this is documented as only working for packages which exist in crates.io.
Add parsing of the SRC_URIs for git repos and include `[patch]` sections to redirect to the checked out source repos which the bitbake fetcher has already populated. There are still cases which don't work - if you have multiple copies of the same repo with different revisions, there's currently no way to represent that and anything using a repo which has a virtual manifest will fail to build (see https://github.com/rust-lang/cargo/issues/4934).
