gitweb: Refactor 'log' action generation, adding git_log_body()

Put the main part of 'log' view generation into git_log_body,
similarly how it is done for 'shortlog' and 'history' views (and
also for 'tags' and 'heads' views).

This is preparation for extracting common code between 'log',
'shortlog' and 'history' actions.
