Even if we find snapshot-prefix in the repo configuration, we are not
writing it out into the rc- file, so setting the value does not have any

Though SHA1 is broken, HMAC-SHA1 is still fine. But let's not push our

This adds support for kernel.org style signatures where the uncompressed
tar archive is signed and compressed later. The signature is valid for
all tar* snapshots.
We have a filter which snapshots may be generated and downloaded. This has
to allow tar signatures now even if tar itself is not allowed. To simplify
things we allow all signatures.

We use POSIX advisory record locks to control access to cache slots, but
these have an unhelpful behaviour in that they are released when any
file descriptor referencing the file is closed by this process.
Mostly this is okay, since we know we won't be opening the lock file
anywhere else, but there is one place that it does matter: when we
restore stdout we dup2() over a file descriptor referring to the file,
thus closing that descriptor.
Since we restore stdout before unlocking the slot, this creates a window
during which the slot content can be overwritten. The fix is reasonably
straightforward: simply restore stdout after unlocking the slot, but the
diff is a bit bigger because this requires us to move the temporary
stdout FD into struct cache_slot.

Update to git version v2.18.0. Required changes follow upstream commits:
* Convert find_unique_abbrev* to struct object_id
(aab9583f7b5ea5463eb3f653a0b4ecac7539dc94)
* sha1_file: convert read_sha1_file to struct object_id
(b4f5aca40e6f77cbabcbf4ff003c3cf30a1830c8)
* sha1_file: convert sha1_object_info* to object_id
(abef9020e3df87c441c9a3a95f592fce5fa49bb9)
* object-store: move packed_git and packed_git_mru to object store
(a80d72db2a73174b3f22142eb2014b33696fd795)
* treewide: rename tree to maybe_tree
(891435d55da80ca3654b19834481205be6bdfe33)
The changed data types required some of our own functions to be converted
to struct object_id:
ls_item
print_dir
print_dir_entry
print_object
single_tree_cb
walk_tree
write_tree_link
And finally we use new upstream functions that were added for
struct object_id:
hashcpy -> oidcpy
sha1_to_hex -> oid_to_hex

Read signatures from the notes refs refs/notes/signatures/$FORMAT where
FORMAT is one of our archive formats ("tar", "tar.gz", ...). The note
is expected to simply contain the signature content to be returned when
the snapshot "${filename}.asc" is requested, so the signature for
cgit-1.1.tar.xz can be stored against the v1.1 tag with:
git notes --ref=refs/notes/signatures/tar.xz add -C "$(
gpg --output - --armor --detach-sign cgit-1.1.tar.xz |
git hash-object -w --stdin
)" v1.1
and then downloaded by simply appending ".asc" to the archive URL.

instead of the repository basename. For example, files downloaded from
the linux-stable.git repository should be named linux-$VERSION and not
linux-stable-$VERSION, which can be achieved by setting:

This helps tracking what git version cgit uses. The security implications are
low as anybody can look up the version of our submodule anyway. The paranoid

This is mostly taken from Git's doc/Makefile, although simplified for
our use. The output now uses Asciidoc's default CSS which I think looks
a bit nicer than the Docbook formatting; as a result of this we no
longer need our custom .css file.
A side effect of this change is that temporary files generated from the
HTML output no longer conflict with the manpage output format (because
any temporary HTML output files use names derived from the output
filename which includes .html).

The html documentation is generated using a2x which calls docbook tools
to do the work. The generate.consistent.ids parameter ensures that when
the docbook stylesheet assigns an id value to an output element it is
consistent as long as the document structure has not changed.
Having consistent html files reduces frivolous changes between builds.
Distributions can more easily deploy multiple architecture builds and
compare changes between package versions. End-users avoid needless
changes in files deployed or backed up.
The generate.consistent.ids parameter was added in docbook-xsl-1.77.0.
Older versions gracefully ignore the parameter, so we can pass the
parameter unconditionally. Most distributions contain docbook-xsl newer
than 1.77.0. This includes Fedora, Debian, Ubuntu, and RHEL/CentOS 7.
RHEL/CentOS 6 and Debian Wheezy (old stable) ship with an older version,
unsurprisingly.
