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".

bookmarks: backed out new message from changeset 52c7e171e355 Not strictly a bugfix, hasn't achieved consensus yet.

clone: print bookmark name when clone activates a bookmark Similar to the message that prints the checked out branch name. Without this, the user might accidentally move the @ bookmark.

clone: activate @ bookmark if updating to it The message "updating bookmark @ failed!" in test-bookmarks-pushpull.t is correct, because the changeset that the @ bookmark points to is not pushed to the target repository.

test-clone.t: check that branch "@" is not automatically checked out This verifies that c9339efed653 fixes the second problem mentioned in issue3677.

test-bookmarks.t: check that bookmark "default" is not automatically checked out This verifies that c9339efed653 fixes the problem originally reported in issue3677.

clone: make sure to use "@" as bookmark and "default" as branch (issue3677) Before this change a bookmark named "default" or a branch named "@" would cause the wrong changeset to be checked out. The change in output of test-hardlinks.t is due to the fact that no unneeded tag lookups for the tags "@" or "default" happen, therefore the cache file is not created.
