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.

This will allow us to use this nice wrapper function elsewhere, avoiding
dealing with the diff queue when we only need to inspect a filepair.

for_each_ref() callback functions were taught to name the objects
not with "unsigned char sha1[20]" but with "struct object_id".

One of the most frequent questions on the mailing list relates to the
idle time in the repository list. The answer to this is to use the
"agefile" feature to calculate the time of the last change whenever the
repository receives changes.
Add a sample post-receive hook in a new "contrib" directory so that we
can just point people at the repository in the future.

Sparse complains about this table because we use the integer zero as the
NULL pointer. Use this as an opportunity to reformat the table so that
it always contains 8 elements per row, making it easier to see which
values are being set and which are not.

Sparse complains that we are using a plain integer as a NULL pointer
here, but in fact we do not have to specify a value for this variable at
all since it has static storage duration and thus will be initialized to
NULL by the compiler.

In commit 936295c (Simplify commit and tag parsing, 2015-03-03), the
commit and tag parsing code was refactored. This broke tag messages in
ui-tag since the line after the tagger header was erroneously skipped.
Rework parse_user() and skip the line manually outside parse_user().

If CGit is killed while it holds a lock on a cache slot (for example
because it is taking too long to generate a page), the lock file will be
left in place. This prevents any future attempt to use the same slot
since it will fail to exclusively create the lock file.
Since CGit is the only program that should be manipulating lock files,
we can use advisory locking to detect whether another process is
actually using the lock file or if it is now stale.
I have confirmed that this works on Linux by setting a short TTL in a
custom cgitrc and running the following with CGit patched to print a
message to stderr if the fcntl(2) fails:
$ export CGIT_CONFIG=$PWD/cgitrc
$ export QUERY_STRING=url=cgit/tree/ui-shared.c
$ ./cgit |
grep -v -e '^<div class=.footer.>' \
-e '^Last-Modified: ' \
-e ^'Expires: ' >expect
$ seq 50000 | dd bs=8192 |
parallel -j200 "diff -u expect <(./cgit |
grep -v -e '^<div class=.footer.>' \
-e '^Last-Modified: ' \
-e ^'Expires: ') || echo BAD"
This printed the fail message several times without ever printing "BAD".

The starts_with() check was broken in two ways: For one thing, the
parameters were passed in the wrong order, for another thing,
starts_with() returns 1 if the string starts with the prefix (not 0).
Note that this bug existed since commit 02a545e (Add support for cloning
over http, 2008-08-06) but only pops in in corner cases.
