gitweb: allow extra breadcrumbs to prefix the trail

Browse Source 
There are often parent pages logically above the gitweb projects
list, e.g. home pages of the organization and department that host
the gitweb server. This change allows you to include links to those
pages in gitweb's breadcrumb trail.

Additional links to be added to the start of the breadcrumb trail before
the home link, to pages that are logically "above" the gitweb projects
list, such as the organization and department which host the gitweb
server. Each element of the list is a reference to an array, in which
element 0 is the link text (equivalent to `$home_link_str`) and element
1 is the target URL (equivalent to `$home_link`).

For example, the following setting produces a breadcrumb trail like
"home / dev / projects / ..." where "projects" is the home link.
