merge(3p/git): Merge git subtree at v2.29.2

This also bumps the stable nixpkgs to 20.09 as of 2020-11-21, because
there is some breakage in the git build related to the netrc
credentials helper which someone has taken care of in nixpkgs.

The stable channel is not used for anything other than git, so this
should be fine.

'git gc' tries very hard not to delete objects that are referenced
anywhere in your repository. In
particular, it will keep not only objects referenced by your current set
of branches and tags, but also objects referenced by the index,
remote-tracking branches, refs saved by 'git filter-branch' in
refs/original/, reflogs (which may reference commits in branches
that were later amended or rewound), and anything else in the refs/* namespace.
If you are expecting some objects to be deleted and they aren't, check
all of those locations and decide whether it makes sense in your case to
remove those references.

On the other hand, when 'git gc' runs concurrently with another process,
there is a risk of it deleting an object that the other process is using
