[RFCv4 3/3] gitweb: link to patch(es) view from commit and log views

[Giuseppe Bilotta <giuseppe.bilotta@xxxxxxxxx>]

We link to patch view in commit and commitdiff view, and to patches view
in log and shortlog view.

In (short)log view, the link is only offered when the number of commits
shown is no more than the allowed maximum number of patches.
