non-existent object IDs so we don't want them to be cached forever.

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.

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.

When clicking on "log" from a tag we end up showing the log of whatever
branch we used to reach the tag. If the tag doesn't point onto a branch
then the tagged commit won't appear in this output.
By linking to tags with the head parameter instead of the "id" parameter
the log link will show the log of the tag. This is clearly desirable
when the tag has been reached from the refs UI and changing the
behaviour for tag decorations makes them match branch decorations where
log -> decoration -> log shows the log of the decoration.

prefixcmp() and suffixcmp() have been remove, functionality is now

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_get_cmd()
* All cgit command functions.
* cgit_clone_info()
* cgit_clone_objects()
* 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.

This leverages the new lua support. See
filters/simple-authentication.lua for explaination of how this works.
There is also additional documentation in cgitrc.5.txt.
Though this is a cookie-based approach, cgit's caching mechanism is
preserved for authenticated pages.
Very plugable and extendable depending on user needs.
The sample script uses an HMAC-SHA1 based cookie to store the
currently logged in user, with an expiration date.

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.

The CGit configuration variable virtual_root is normalized so that it
does not have a trailing '/' character, but it is allowed to be empty
(the empty string and NULL have different meanings here) and there is
code that is insufficiently cautious when checking if it ends in a '/':
if (virtual_root[strlen(virtual_root) - 1] != '/')
Clearly this check is redundant, but rather than simply removing it we
get a slight efficiency improvement by switching the normalization so
that the virtual_root variable always ends in '/'. Do this with a new
"ensure_end" helper.

While doing this, remove declarations from header files where the

The return values of these functions are essentially constant and should
never be modified.
Note that this will introduce a compiler warning when we try to free the
return value of any of these functions. However, given that all of these
currently return statically allocated strings in some cases, they need
to be refactored before this can be done anyway.

Since tail is initialized to 0, we will never get a warning on the last
if statement, but recent gcc complains anyway. So, we initialize len as
well. Future gcc versions should be able to optimize this out anyway.
cgit_self_link() is a void function but implements each case it handles
by doing "return <another_void_function>" which is not valid C; section
6.8.6.4 of C11 says:
A return statement with an expression shall not appear in a
function whose return type is void.
Fix this by removing the return keywords and converting the final code
block into an "else".
