Avoid wrong disambiguation that would link logs/trees of tags and heads which share the same name to the same page, leading to a disambiguation that would prefer the tag, thus making it impossible to access the corresponding head log and tree without hacking the url by hand.

It does it by using full refname (with 'refs/heads/' or 'refs/tags/' prefix) instead of shortened one in the URLs in 'heads' and 'tags' tables. This makes URLs (and refs) provided by gitweb unambiguous.

Based on the patch by Guillaume Seguin, which solved the same problem
in slightly different way, by re-adding 'refs/heads/' or 'refs/tags/'.
I think this way is slightly better.
Note that there is companion RFC patch (which is not a part of this
mini-series) which added check if the refname is ambiguous in git_tag:
  "gitweb: Try harder in parse_tag; perhaps it was given ambiguous name"
