Currently the vendoring support in Cargo primarily only allows replacing
registry sources, e.g. crates.io. Other networked sources of code, such as git
repositories, cannot currently be replaced. The purpose of this commit is to
support vendoring of git dependencies to eventually have support implemented in
the `cargo-vendor` subcommand.
Support for vendoring git repositories required a few subtle changes:
* First and foremost, configuration for source replacement of a git repository
was added. This looks similar to the `Cargo.toml` configuration of a git
source.
* The restriction around checksum providing sources was relaxed. If a
replacement source provides checksums but the replaced source doesn't then
that's now considered ok unlike it being an error before.
* Lock files can be generated for crates.io crates against vendored sources, but
lock files cannot be generated against git sources. A lock file must
previously exist to make use of a vendored git source.
* The `package` field of `.cargo-checksum.json` is now optional, and it is
intended to be omitted for git sources that are vendored.
