[PATCH 5/7] gitweb: Use parse_rev_list in git_shortlog and git_history

[Jakub Narebski <jnareb@gmail.com>]

Use parse_rev_list in git_shortlog and git_history, and modify
git_shortlog_body and git_history_body to accept parse_rev_list
output; in the future we can remove support for older unparsed
revision list from git_shortlog_body and git_history_body.

Other places when we can use parse_rev_list are git_log and git_rss.
