Move the check that detects "HEAD" refs that do not point at a branch
into `refs_fsck()`. This follows the same motivation as the preceding
commit.

While most of the logic that verifies the consistency of refs is
driven by `refs_fsck()`, we still have a small handful of checks in
`fsck_head_link()`. These checks don't use the git-fsck(1) reporting
infrastructure, and as such it's impossible to for example disable
some of those checks.
One such check detects refs that point to the all-zeroes object ID.
Extract this check into the generic `refs_fsck_ref()` function that is
used by both the "files" and "reftable" backends.
Note that this will cause us to not return an error code from
`fsck_head_link()` anymore in case this error was detected. This is fine
though: the only caller of this function does not check the error code
anyway. To demonstrate this, adapt the function to drop its return value
altogether. The function will be removed in a subsequent commit anyway.

The beginning of SHA1-SHA256 interoperability work.
* bc/sha1-256-interop-01:
t1010: use BROKEN_OBJECTS prerequisite
t: allow specifying compatibility hash
fsck: consider gpgsig headers expected in tags
rev-parse: allow printing compatibility hash
docs: add documentation for loose objects
docs: improve ambiguous areas of pack format documentation
docs: reflect actual double signature for tags
docs: update offset order for pack index v3
docs: update pack index v3 format
When we're creating a tag, we want to make sure that gpgsig and
gpgsig-sha256 headers are allowed for the commit. The default fsck
behavior is to ignore the fact that they're left over, but some of our
tests enable strict checking which flags them nonetheless. Add
improved checking for these headers as well as documentation and several
tests.

Add glue code in 'refs/reftable-backend.c' which calls the reftable
library to perform the fsck checks. Here we also map the reftable errors
to Git' fsck errors.
Introduce a check to validate table names for a given reftable stack.
Also add 'badReftableTableName' as a corresponding error within Git. The
reftable specification mentions:
It suggested to use
${min_update_index}-${max_update_index}-${random}.ref as a naming
convention.
So treat non-conformant file names as warnings.
While adding the fsck header to 'refs/reftable-backend.c', modify the
list to maintain lexicographical ordering.

We assume the "packed-refs" won't be empty and instead has at least one
line in it (even when there are no refs packed, there is the file header
line). Because there is no terminating LF in the empty file, we will
report "packedRefEntryNotTerminated(ERROR)" to the user.
However, the runtime code paths would accept an empty "packed-refs"
file, for example, "create_snapshot" would simply return the "snapshot"
without checking the content of "packed-refs". So, we should skip
checking the content of "packed-refs" when it is empty during fsck.
After 694b7a1999 (repack_without_ref(): write peeled refs in the
rewritten file, 2013-04-22), we would always write a header into the
"packed-refs" file. So, versions of Git that are not too ancient never
write such an empty "packed-refs" file.
As an empty file often indicates a sign of a filesystem-level issue, the
way we want to resolve this inconsistency is not make everybody totally
silent but notice and report the anomaly.
Let's create a "FSCK_INFO" message id "EMPTY_PACKED_REFS_FILE" to report
to the users that "packed-refs" is empty.

"git fsck" becomes more careful when checking the refs.
* sj/ref-consistency-checks-more:
builtin/fsck: add `git refs verify` child process
packed-backend: check whether the "packed-refs" is sorted
packed-backend: add "packed-refs" entry consistency check
packed-backend: check whether the refname contains NUL characters
packed-backend: add "packed-refs" header consistency check
packed-backend: check if header starts with "# pack-refs with: "
packed-backend: check whether the "packed-refs" is regular file
builtin/refs: get worktrees without reading head information
t0602: use subshell to ensure working directory unchanged
We presently use the ".txt" extension for our AsciiDoc files. While not
wrong, most editors do not associate this extension with AsciiDoc,
meaning that contributors don't get automatic editor functionality that
could be useful, such as syntax highlighting and prose linting.
It is much more common to use the ".adoc" extension for AsciiDoc files,
since this helps editors automatically detect files and also allows
various forges to provide rich (HTML-like) rendering. Let's do that
here, renaming all of the files and updating the includes where
relevant. Adjust the various build scripts and makefiles to use the new
extension as well.
Note that this should not result in any user-visible changes to the
documentation.
