Vincent Ambo f4609b896f 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.

test_description='Test Git when git repository is located at root
This test requires write access in root. Do not bother if you do not
have a throwaway chroot or VM.
Script t1509/prepare-chroot.sh may help you setup chroot, then you
can chroot in and execute this test from there.
