cgit.c: add 'clone-url' setting with support for macro expansion

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.
