[PATCHv7 03/11] gitweb: git_get_heads_list accepts an optional list of refs

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

git_get_heads_list(limit, class1, class2, ...) can now be used to retrieve
refs/class1, refs/class2 etc. Defaults to ('heads', 'remotes') or ('heads')
depending on whether the 'remote_heads' feature is enabled or not.
