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.

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.

Allow using a user-specified value for the prefix in snapshot files

linux-stable-$VERSION, which can be achieved by setting:

Numerous changes were made to git functions to use an object_id
structure rather than sending sha1 hashes as raw unsigned character
arrays. The functions that affect cgit are: parse_object,
lookup_commit_reference, lookup_tag, lookup_tree, parse_tree_indirect,
diff_root_tree_sha1, diff_tree_sha1, and format_display_notes.
Commit b2141fc (config: don't include config.h by default) made it
necessary to that config.h be explicitly included when needed.
Commit 07a3d41 (grep: remove regflags from the public grep_opt API)
removed one way of specifying the ignore-case grep option.

Upstream git is replacing 'unsigned char sha1[20]' with 'struct object_id
oid'. We have some code that can be changed independent from upstream. So
here we go...
cgit_print_error_page() has the advantage that it sets a suitable HTTP
status code for the response. Note that setting "mimetype" is redundant
here since it cannot have changed since being initialized in
cgit.c::prepare_context(), so we do not need to worry that
cgit_print_error_page() does not set it.

prefixcmp() and suffixcmp() have been remove, functionality is now
provided by starts_with() and ends_with(). Retrurn values have been
changed, so instead of just renaming we have to fix logic.
Everything else looks just fine.
Drop the context parameter from the following functions (and all static
helpers used by them) and use the global context instead:
* cgit_print_http_headers()
* cgit_print_docstart()
* cgit_print_pageheader()
Remove context parameter from all commands
Drop the context parameter from the following functions (and all static

* cgit_clone_info()

* cgit_clone_head()
* cgit_print_plain()
* cgit_show_stats()
In initialization routines, use the global context variable instead of
passing a pointer around locally.
Remove callback data parameter for cache slots
This is no longer needed since the context is always read from the
global context variable.

Change the existing cgit_{open,close,fprintf}_filter functions to
delegate to filter-specific implementations accessed via function
pointers on the cgit_filter object.
We treat the "exec" filter type slightly specially here by putting its
structure definition in the header file and providing an "init" function
to set up the function pointers. This is required so that the
ui-snapshot.c code that applies a compression filter can continue to use
the filter interface to do so.

It's a bit tedious to have to do this here too. If we encounter other

In cgit_print_snapshot_links() we strip leading "v" and "V", while we
currently only prepend a lower case "v" when parsing a snapshot file
name. This results in broken snapshot links for tags that start with an
upper case "V". Avoid this by prepending a "V" as a fallback.

Use "struct strbuf" from Git to remove the limit on file path length.
Notes on scan-tree:
This is slightly involved since I decided to pass the strbuf into
add_repo() and modify if whenever a new file name is required, which
should avoid any extra allocations within that function. The pattern
there is to append the filename, use it and then reset the buffer to its
original length (retaining a trailing '/').
Notes on ui-snapshot:
Since write_archive modifies the argv array passed to it we
copy the argv_array values into a new array of char* and then free the
original argv_array structure and the new array without worrying about
what the values now look like.
Signed-off-by: John Keeping <john@keeping.me.uk>
This removes many uses of "fmt" which uses a fixed size static pool of
fixed size buffers. Instead of relying on these, we now pass around
argument lists for as long as possible before using a strbuf to render
content of an arbitrary size.

While doing this, remove declarations from header files where the
corresponding definition is declared "static" in order to avoid build
errors.
Also re-order existing headers in ui-*.c so that the file-specific
header always comes immediately after "cgit.h", helping with future
consistency.

parse_archive_args does not pass PARSE_OPT_KEEP_ARGV0 to parse_args,
which means the first argument will be discarded, as though it were a

a dummy argument to prevent this from happening.

Since cgit snapshots of tags are often used for releases, we don't
want the rarely used feature of the gzip compressor that includes
an embedded timestamp into the archive, since this makes each tarball
of the same (potentially signed) tag different.
This commit refactors the archive handling code a bit so that each
different format is able to run with an arbitrary argv for the filter.
When cgit learned to setup environment variables for certain repo
settings before invoking a filter process, the setup occurred inside
cgit_open_filter().
This patch moves the setup out of cgit_open_filter() and into
prepare_repo_cmd() to prepare for additional uses of these variables.

When downloading a snapshot, the snapshot name will often contain the repo

correct revision is downloaded even if no specific revision is specified.
PS: this only occurs if neither 'h' nor 'id' is specified in the query-
string.
PPS: this also fixes a bug which occurs when trying to download a filename
with an unsupported suffix: it used to try to print an error message to
the user but failed since it didn't prepare the output properly.
