Kind regards,

> Teach cgit split the repository link in the top of repository "summary"
> view. This emulates the same behaviour as it's in gitweb.

> This behaviour is not implemented for repositories which have
> "repo.name" set different than "repo.url".

> This feature is controlled by a new config variable:
> "split-summary-repo-link" (disabled by default).

> v5: Rename config variable to split-summary-repo-link
> v4: Implement suggestions from John Keeping (thanks for them :-)):
> * use strchr() instead of strtok_r() and variadic arrays
> * use cgit_repourl() and html_*() instead of cgit_summary_link().
> * add comment why we compare page.url and page.name
> v3: New config variable "summary-enable-split-repo-link", minor cleanup.
> v2: Minor cleanup.
