128910ba23 Separate cgroup support from auto-uid-allocation 
The new experimental feature 'cgroups' enables the use of cgroups for
all builds. This allows better containment and enables setting
resource limits and getting some build stats.

bb411e4ae1 Fix progress bar flicker with -L 
This was caused by -L calling setLogFormat() again, which caused the
creation of a new progress bar without destroying the old one. So we
had two progress bars clobbering each other.

We should change 'logger' to be a smart pointer, but I'll do that in a
future PR.

Fixes #6931.

1ba5b3e001 Make moveFile more atomic 
Rather than directly copying the source to its dest, copy it first to a
temporary location, and eventually move that temporary.
That way, the move is at least atomic from the point-of-view of the destination

90f9680733 Only use renameFile where needed

c5db1821a9 Re-implement the recursive directory copy 
The recursive copy from the stl doesn’t exactly do what we need because
1. It doesn’t delete things as we go
2. It doesn’t keep the mtime, which change the nars

So re-implement it ourselves. A bit dull, but that way we have what we want

6f89fb6008 rename: Fallback to a copy if the filesystems mismatch 
In `nix::rename`, if the call to `rename` fails with `EXDEV` (failure
because the source and the destination are in a different filesystems)
switch to copying and removing the source.

To avoid having to re-implement the copy manually, I switched the
function to use the c++17 `filesystem` library (which has a `copy`
function that should do what we want).

Fix #6262

Fix flake input completion for InstallablesCommands 
Defers completion of flake inputs until the whole command line is parsed
so that we know what flakes we need to complete the inputs of.

Previously, `nix build flake --update-input <Tab>` always behaved like
`nix build . --update-input <Tab>`.

ca2be509b9 Verify $HOME is owned by current user in getHome(), if it exists. 
Useful because a default `sudo` on darwin doesn't clear `$HOME`, so things like `sudo nix-channel --list`
will surprisingly return the USER'S channels, rather than `root`'s.

Other counterintuitive outcomes can be seen in this PR description:
