2020-05-30	Improve ref validity checking in fetchGit	Nikola Knezevic
	The previous regex was too strict and did not match what git was allowing. It could lead to `fetchGit` not accepting valid branch names, even though they exist in a repository (for example, branch names containing `/`, which are pretty standard, like `release/1.0` branches). The new regex defines what a branch name should NOT contain. It takes the definitions from `refs.c` in https://github.com/git/git and `git help check-ref-format` pages. This change also introduces a test for ref name validity checking, which compares the result from Nix with the result of `git check-ref-format --branch`.
2020-04-07	Backport libfetchers from the flakes branch	Eelco Dolstra
	This provides a pluggable mechanism for defining new fetchers. It adds a builtin function 'fetchTree' that generalizes existing fetchers like 'fetchGit', 'fetchMercurial' and 'fetchTarball'. 'fetchTree' takes a set of attributes, e.g. fetchTree { type = "git"; url = "https://example.org/repo.git"; ref = "some-branch"; rev = "abcdef..."; } The existing fetchers are just wrappers around this. Note that the input attributes to fetchTree are the same as flake input specifications and flake lock file entries. All fetchers share a common cache stored in ~/.cache/nix/fetcher-cache-v1.sqlite. This replaces the ad hoc caching mechanisms in fetchGit and download.cc (e.g. ~/.cache/nix/{tarballs,git-revs*}). This also adds support for Git worktrees (c169ea59049f861aaba429f48b828d0820b74d1d).
