John Keeping c712d5ac43 snapshot: support archive signatures
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.

John Keeping 48f175083a Makefile: drive asciidoc directly for HTML output
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).

John Keeping 9d751e7eec parsing: don't clear existing state with empty input
Since commit c699866 (parsing: clear query path before starting,
2017-02-19), we clear the "page" variable simply by calling
cgit_parse_url() even if the URL is empty.  This breaks a URL like:

	.../cgit?p=about

which is generated when using the "root-readme" configuration option.

This happens because "page" is set to "about" when parsing the query
string before we handle the path (which is empty, but non-null).

It turns out that this is not the only case which is broken, but
specifying repository and page via query options has been broken since
before the commit mentioned above, for example:

	.../cgit?r=git&p=log

Fix both of these by allowing the previous state to persist if PATH_INFO
is empty, falling back to the query parameters if no path has been
requested.

John Keeping 3b485cc542 cache: flush stdio before restoring FDs

John Keeping c699866699 parsing: clear query path before starting
By specifying the "url" query parameter multiple times it is possible to
end up with ctx.qry.vpath set while ctx.repo is null, which triggers an
invalid code path from cgit_print_pageheader() while printing path
crumbs, resulting in a null dereference.

The previous patch fixed this segfault, but it makes no sense for us to
clear ctx.repo while leaving ctx.qry.path set to the previous value, so
let's just clear it here so that the last "url" parameter given takes
full effect rather than partially overriding the effect of the previous
value.

without also setting want_repo so it shouldn't be possible to fail this
test, but the check in cgit.c is in the wrong order so it is possible to
specify a query string like "?p=log&path=foo/bar" to end up here without
a valid repository.

John Keeping 35df710a1f configfile: fix EOF handling
Currently we can end up passing EOF to isspace(), which is in fact
libgit's sane_isspace which does:

	((sane_ctype[(unsigned char)(x)] & (GIT_SPACE)) != 0)

It is very unlikely that EOF cast to "unsigned char" will end up in a
character that has the GIT_SPACE bit set, but the standard only requires
that EOF be a negative integer, so it could access any value in the
sane_ctype array.

If it does end up returning true for isspace() then this loop will never
terminate, so handle EOF as a special value in the same way as the other
loops in this function.

John Keeping 75298209bf ui-atom: avoid DATE_STRFTIME
Git's DATE_STRFTIME ignores the timezone argument and just uses the
local timezone regardless of whether the "local" flag is set.

Since Atom accepts ISO8601 dates [1], we can use Git's
DATE_ISO8601_STRICT instead, which does get this right.  Additionally,
we never use the local timezone here so we can use the
date_mode_from_type() wrapper to simplify the code a bit.

John Keeping bdcbe0922d ui-stats: cast pointer before checking for zero
We abuse the "void *util" field as a counter and recently started to
cast it to a uintptr_t to avoid risking nasal demons by performing
arithmetic on a void pointer.

However, compilers are also known to do "interesting" things if they
know that a pointer is or isn't NULL.  Make this safer by checking if
the counter (after casting) is non-zero rather than checking if the
pointer is non-null.

John Keeping 7105a78b17 ui-tree: use "sane" isgraph()
Git's git-compat-util.h defines a "sane ctype" that does not use locale
information and works with signed chars, but it does not include
isgraph() so we have included ctype.h ourselves.

However, this means we have to include a system header before
git-compat-util.h which may lead to the system defining some macros
(e.g. _FILE_OFFSET_BITS on Solaris) before git-compat-util.h redefines
them with a different value.  We cannot include ctype.h after
git-compat-util.h because we have defined many of its functions as
macros which causes a stream of compilation errors.

Defining our own "sane" isgraph() using Git's sane isprint() and
isspace() avoids all of these problems.

John Keeping 2ef4edee19 tests: allow shell to be overridden
On some systems (e.g. Solaris), /bin/sh is not a POSIX shell.  Git
already provides suitable overrides in its config.mak.uname file and we
provide cgit.conf to allow the user to further change this.

The code for this is taken from Git's t/Makefile, meaning that we now
invoke the tests in the same way that Git does.

John Keeping 30304d8156 log: allow users to follow a file
Teach the "log" UI to behave in the same way as "git log --follow", when
given a suitable instruction by the user.  The default behaviour remains
to show the log without following renames, but the follow behaviour can
be activated by following a link in the page header.

Follow is not the default because outputting merges in follow mode is
tricky ("git log --follow" will not show merges).  We also disable the
graph in follow mode because the commit graph is not simplified so we
end up with frequent gaps in the graph and many lines that do not
connect with any commits we're actually showing.

We also teach the "diff" and "commit" UIs to respect the follow flag on
URLs, causing the single-file version of these UIs to detect renames.
This feature is needed only for commits that rename the path we're
interested in.

For commits before the file has been renamed (i.e. that appear later in
the log list) we change the file path in the links from the log to point
to the old name; this means that links to commits always limit by the
path known to that commit.  If we didn't do this we would need to walk
down the log diff'ing every commit whenever we want to show a commit.
The drawback is that the "Log" link in the top bar of such a page links
to the log limited by the old name, so it will only show pre-rename
commits.  I consider this a reasonable trade-off since the "Back" button
still works and the log matches the path displayed in the top bar.

Since following renames requires running diff on every commit we
consider, I've added a knob to the configuration file to globally
enable/disable this feature.  Note that we may consider a large number
of commits the revision walking machinery no longer performs any path
limitation so we have to examine every commit until we find a page full
of commits that affect the target path or something related to it.

can just point people at the repository in the future.
