There is no way that "tag" can be null here.

We have already called strlen() on "path" by the time we get here, so we
know it can't be null.

parse_configfile() takes a "const char *" and doesn't hold any
references to it after it returns; there is no reason to pass it a
duplicate.

Everywhere else in this function we do not check whether the value is
null and parse_configfile() never passes a null value to this callback.

The about page used to display just fine, but images were broken: The
binary image data was embedded in html code.
Use cgit_print_plain() to send images in plain mode and make them
available on about page.

Most errors we generate are (potentially) transient, such as
non-existent object IDs so we don't want them to be cached forever.

This also allows us to return proper HTTP error codes when the requested
tree is not found and display an error message in one case (invalid path
inside valid commit) where we previously just displayed an empty page.

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.

This is a bugfix as well as an improvement to the HTTP status code
handling since previously we would not print HTTP headers on any of
these code paths.

These are more-or-less one-to-one translations but in the final hunk we
gain an HTTP error code where we used to send "200 OK", which is an
improvement.

Requesting a text/plain patch with bad commit id made cgit send text
without proper http headers. This results in "500 Internal Server Error"
with "Premature end of script headers" in server logs.
So print http headers before error message and return.

Commit caed6cb (ui-shared: show absolute time in tooltip for relative
dates, 2014-12-20) added a toolip when we show a relative time.
However, in some cases we show a short date (that is, the date but not
the time) if an event was sufficiently far in the past and that commit
did not update that case to add the same tooltip.

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.

git-compat-util.h may define values that affect how system headers are

git-compat-util.h may define various values that affect the
interpretation of system headers. In most places we include cgit.h
first, which pulls in git-compat-util.h, but this file does not depend
on anything else in CGit, so use git-compat-util.h directly.

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.

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.
