[PATCH 0/3] Add git_project_index, improve href()

This series of patches introduces "project_index" view, which is text/plain equivalent of projects list view, again. This time it is accompanied by the patch which adds links to this view.

"project_index" view has at least two uses: first, to automatically generate gitweb project index file (which we then edit, e.g. removing some projects from being visible from gitweb and correcting ownership information). Second, to get list of projects for scripts, in very easily parseable form.

Even if patches 1 and 3 got discarded, patch 2 is I think worth applying. It finishes consolidation of URL generation.

Shortlog:
 [PATCH 1/3] gitweb: Add git_project_index for generating index.aux
 [PATCH 2/3] gitweb: Allow for href() to be used for projectless links
 [PATCH 3/3] gitweb: Add link to "project_index" view to "project_list" page

P.S. Should shortlog be before, or after diffstat (if it matters)?
