e5b17bda8b git: ensure correct git directory setup with -h
Ensure correct git directory setup when -h is passed with commands. This
specifically applies to repos with special help text configuration
variables and to commands run with -h outside a repository. This
will also protect against test failures in the upcoming change to BUG in
prepare_repo_settings if no git directory exists.

Note: this diff is better seen when ignoring whitespace changes.

f2a454e0a5 unpack-trees: improve performance of next_cache_entry
To find the first non-unpacked cache entry, `next_cache_entry` iterates
through index, starting at `cache_bottom`. The performance of this in full
indexes is helped by `cache_bottom` advancing with each invocation of
`mark_ce_used` (called by `unpack_index_entry`). However, the presence of
sparse directories can prevent the `cache_bottom` from advancing in a sparse
index case, effectively forcing `next_cache_entry` to search from the
beginning of the index each time it is called.

The `cache_bottom` must be preserved for the sparse index (see 17a1bb570b
(unpack-trees: preserve cache_bottom, 2021-07-14)). Therefore, to retain the
benefit `cache_bottom` provides in non-sparse index cases, a separate `hint`
position indicates the first position `next_cache_entry` should search,
updated each execution with a new position.

4d1cfc1351 reset: make --mixed sparse-aware
Remove the `ensure_full_index` guard on `read_from_tree` and update `git
reset --mixed` to ensure it can use sparse directory index entries wherever
possible. Sparse directory entries are reset using `diff_tree_oid`, which
requires `change` and `add_remove` functions to process the internal
contents of the sparse directory. The `recursive` diff option handles cases
in which `reset --mixed` must diff/merge files that are nested multiple
levels deep in a sparse directory.

The use of pathspecs with `git reset --mixed` introduces scenarios in which
internal contents of sparse directories may be matched by the pathspec. In
order to reset *all* files in the repo that may match the pathspec, the
following conditions on the pathspec require index expansion before
performing the reset:

* "magic" pathspecs
* wildcard pathspecs that do not match only in-cone files or entire sparse
  directories
* literal pathspecs matching something outside the sparse checkout
  definition

20ec2d034c reset: make sparse-aware (except --mixed)
Remove `ensure_full_index` guard on `prime_cache_tree` and update
`prime_cache_tree_rec` to correctly reconstruct sparse directory entries in
the cache tree. While processing a tree's entries, `prime_cache_tree_rec`
must determine whether a directory entry is sparse or not by searching for
it in the index (*without* expanding the index). If a matching sparse
directory index entry is found, no subtrees are added to the cache tree
entry and the entry count is set to 1 (representing the sparse directory
itself). Otherwise, the tree is assumed to not be sparse and its subtrees
are recursively added to the cache tree.

c01b1cbd47 reset: integrate with sparse index
Disable `command_requires_full_index` repo setting and add
`ensure_full_index` guards around code paths that cannot yet use sparse
directory index entries. `reset --soft` does not modify the index, so no
compatibility changes are needed for it to function without expanding the
index. For all other reset modes (`--mixed`, `--hard`, `--keep`, `--merge`),
the full index is expanded to prevent cache tree corruption and invalid
variable accesses.

Additionally, the `read_cache()` check verifying an uncorrupted index is
moved after argument parsing and preparing the repo settings. The index is
not used by the preceding argument handling, but `read_cache()` must be run
*after* enabling sparse index for the command (so that the index is not
expanded unnecessarily) and *before* using the index for reset (so that it
is verified as uncorrupted).

86609db9da sparse-index: update command for expand/collapse test
In anticipation of `git reset --hard` being able to use the sparse index
without expanding it, replace the command in `sparse-index is expanded and
converted back` with `git reset -- folder1/a`. This command will need to
expand the index to work properly, even after integrating the rest of
`reset` with sparse index.

71471b2a7c reset: preserve skip-worktree bit in mixed reset
Change `update_index_from_diff` to set `skip-worktree` when applicable for
new index entries. When `git reset --mixed <tree-ish>` is run, entries in
the index with differences between the pre-reset HEAD and reset <tree-ish>
are identified and handled with `update_index_from_diff`. For each file, a
new cache entry in inserted into the index, created from the <tree-ish> side
of the reset (without changing the working tree). However, the newly-created
entry must have `skip-worktree` explicitly set in either of the following
scenarios:

1. the file is in the current index and has `skip-worktree` set
2. the file is not in the current index but is outside of a defined sparse
   checkout definition

Not setting the `skip-worktree` bit leads to likely-undesirable results for
a user. It causes `skip-worktree` settings to disappear on the
"diff"-containing files (but *only* the diff-containing files), leading to
those files now showing modifications in `git status`. For example, when
running `git reset --mixed` in a sparse checkout, some file entries outside
of sparse checkout could show up as deleted, despite the user never deleting
anything (and not wanting them on-disk anyway).

Additionally, add a test to `t7102` to ensure `skip-worktree` is preserved
in a basic `git reset --mixed` scenario and update a failure-documenting
test from 19a0acc (t1092: test interesting sparse-checkout scenarios,
2021-01-23) with new expected behavior.
