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.

* A "prefix item list" is a list of items that are identified by a string, and
* a unique prefix (if any) is determined for each item.
*
* It is implemented in the form of a pair of `string_list`s, the first one
* duplicating the strings, with the `util` field pointing at a structure whose
* first field must be `size_t prefix_length`.
*
* That `prefix_length` field will be computed by `find_unique_prefixes()`; It
* will be set to zero if no valid, unique prefix could be found.
*
* The second `string_list` is called `sorted` and does _not_ duplicate the
* strings but simply reuses the first one's, with the `util` field pointing at
* the `string_item_list` of the first `string_list`. It will be populated and
* sorted by `find_unique_prefixes()`.
