The original idea was to implement a git-fetcher in Nix's core that supports content hashes[1]. In #3549[2] it has been suggested to actually use `fetchTree` for this since it's a fairly generic wrapper over the new fetcher-API[3] and already supports content-hashes. This patch implements a new git-fetcher based on `fetchTree` by incorporating the following changes: * Removed the original `fetchGit`-implementation and replaced it with an alias on the `fetchTree` implementation. * Ensured that the `git`-fetcher from `libfetchers` always computes a content-hash and returns an "empty" revision on dirty trees (the latter one is needed to retain backwards-compatibility). * The hash-mismatch error in the fetcher-API exits with code 102 as it usually happens whenever a hash-mismatch is detected by Nix. * Removed the `flakes`-feature-flag: I didn't see a reason why this API is so tightly coupled to the flakes-API and at least `fetchGit` should remain usable without any feature-flags. * It's only possible to specify a `narHash` for a `git`-tree if either a `ref` or a `rev` is given[4]. * It's now possible to specify an URL without a protocol. If it's missing, `file://` is automatically added as it was the case in the original `fetchGit`-implementation.
