releasenotes: improve parsing around bullet points Earlier, on parsing the bullet points from existing release notes the bullet points after the first one weren't written correctly to the notes file. This patch makes changes to parsereleasenotesfromfile() function that introduces a new bullet_points data structure that tracks the bullets and associated subparagraph. It also makes necessary changes to the tests related to merging of bullets.

bookmarks: factor method _printer out of for loop in printbookmarks This allows even further customization via extensions for printing bookmarks. For example, in hg-git this would allow printing remote refs by just modifying the 'bmarks' parameter instead of reimplementing the old commands.bookmarks method. Furthermore, there is another benefit: now multiple extensions can chain their custom data to bookmark printing. Previously, an extension could have conflicting bookmark output due to which loaded first and overrode commands.bookmarks. Now they can all play nicely together.

bookmarks: factor out bookmark printing from commands

commands: move activebookmarklabel to bookmarks module This is going to be used in an upcoming patch that moves more methods to bookmarks.py.

commands: replace locking code with a context manager Note that this means that we're unnecessarily creating a transaction in the pure "--inactive" (i.e. when deactivating the current bookmark), but that should be harmless.

bookmarks: factor out adding a list of bookmarks logic from commands We keep the lock in the caller so that future devs are aware of the locking implications.
