bookmarks: remove --active in favor of --list It's weird that we have both --active and --inactive options meaning completely different things. Instead of adding a one-off option, let's document the way to display the active bookmark by using -l/--list. No deprecated option is added since --active isn't released yet.

bookmarks: add explicit option to list bookmarks of the given names This is a generalized form of the --active option. A redundant sorted() call is removed. There was no point to update dict items in lexicographical order.

bookmarks: reject --delete with --inactive which makes no sense A deleted bookmark is neither active nor inactive.

bookmarks: parse out --inactive to action early The --inactive option can't be directly mapped to an action or a modifier. With any names, it means to add/rename to inactive bookmarks. Without names, it means to deactivate the current bookmark. This patch separates them to "inactive" flag and "action == 'inactive'".

bookmarks: parse out implicit "add" action early This prepares for adding -l/--list option, which can be combined with the positional arguments.

bookmarks: clarify that opts['rename'] points to an old bookmark to be renamed

bookmarks: refactor option checking to pick one from --delete/rename/active

bookmarks: convert opts to bytes dict early

bookmarks: pass in formatter to printbookmarks() instead of opts (API) This clarifies that user options have to be processed before calling printbookmarks().

strip: ignore orphaned internal changesets while computing safe strip roots Internal changeset can be safely garbage collected, so we can ignore them during safestrip. (Another phase for internal changeset that must be kept in the repository might be introduced later).
