Some setenv() implementations (e.g. the one in OpenBSD's stdlib)
segfault if we pass a NULL value. Only set environment variables if the
corresponding settings are defined to avoid this.
Note that this is a minor behaviour change as environment variables were
supposed to be set to an empty string if a setting was undefined. Given
that this feature isn't part of any official release yet, there's no
need to worry about backwards compatibility, really. Change the
documentation accordingly.

There's no need to invoke guess_defbranch() for each repo during
scan-path, since repo.defbranch is only used when repo content is
being displayed.
Also, some users prefer to register their projects manually in cgitrc
but they got no benefit from the new repo.defbranch handling.
This patch tries to rectify these issues by only invoking guess_defbranch()
when needed, regardless of how the repo was registered.

The current 'clone-prefix' setting has some known issues:
* All repos get the same 'clone-prefix' value since the setting is not
adopted during repo registration (in cgitrc, or during scan-path traversal),
but only when the setting is used.
* The generated clone-urls for a repo is a combination of 'clone-prefix', a
slash and the repo url. This doesn't work well with e.g. ssh-style urls
like 'git@example.org:repo.git', since the inserted slash will make the
repo relative to the filesystem root.
* If 'remove-suffix' is enabled, the generated clone-urls will not work for
cloning (except for http-urls to cgit itself) since they miss the '.git'
suffix.
The new 'clone-url' setting is designed to avoid the mentioned issues:
* Each repo adopts the default 'clone-url' when the repo is defined. This
allows different groups of repos to adopt different values.
* The clone-urls for a repo is generated by expanding environment variables
in a string template without inserting arbitrary characters, hence any
kind of clone-url can be generated.
* Macro expansion also eases the 'remove-suffix' pain since it's now
possible to define e.g. 'clone-url=git://foo.org/$CGIT_REPO_URL.git' for
a set of repos. A furter improvement would be to define e.g.
$CGIT_REPO_SUFFIX to '.git' for all repos which had their url prettified,
or to store the original $CGIT_REPO_URL in e.g. $CGIT_REPO_REAL_URL before
suffix removal.

Teach CGit to print an ASCII art commit graph to the left of the commit
message, similar to 'git log --graph'. The graph adds extra lines (table
rows) to the log when needed to add/remove/shuffle edges in the graph.
When 'showmsg' is enabled, the graph is automatically padded to account
for the extra lines added by the commit message/notes.
This feature is controlled by a new config variable: "enable-commit-graph"
(disabled by default), and individual repos can control it by setting
"repo.enable-commit-graph".

When using ui-log with path limits, the listing of commits enables parent
rewriting in Git's internal log machinery. This did not work well together
with cgit_diff_commit() which is used to generate the filecount and
linecount numbers for each commit in the log view. cgit_diff_commit() would
operate without any path limits, and would therefore process the full diff
between the commits shown (which, because of parent rewriting, is not the
same as processing the diff for the commit itself). Additionally, the bottom
commit in the log view would (again, because of parent rewriting) have zero
parents, causing us to process the entire diff between the empty tree and
that commit. Since path limits were not in effect, this would (in large
projects) reports thousands of files and millions of lines changed in that
bottom commit.
This patch fixes the issue by applying the same path limit to
cgit_diff_commit() as is applied to the rest of the log view. The result is
that the filecount/linecount now only reflects the diff as it pertains to
the given path limit.

This adds a new function used to generate links to the diff page and uses
it everywhere such links appear (expect for single files in the diffstat
displayed on the commit page: this is now a link to the tree page).
The updated diff-page now expects zero, one or two revision specifiers, in
parameters head, id and id2. Id defaults to head unless otherwise specified,
while head (as usual) defaults to repo.defbranch. If id2 isn't specified, it
defaults to the first parent of id1.
The most important change is of course that now all repo pages (summary, log,
tree, commit and diff) has support for passing on the current branch and
revision, i.e. the road is now open for a 'static' menu with links to all
