subrepo: isolate configuration between each repositories in subrepo tree

Before this patch, repository local configurations are not isolated
between repositories in subrepo tree, because "localrepository"
objects for each subrepositories are created with "ui" instance of the
parent of each ones.

So, local configuration of the parent or higher repositories are
visible also in children or lower ones.

This patch uses "baseui" instead of "ui" to create repository object:
the former contains only global configuration.

This patch also copies 'ui.commitsubrepos' configuration to commit
recursively in subrepo tree, because it may be set in not
"repo.baseui" but "repo.ui".
