bookmarks: make setcurrent with None an error

strip: use bookmarks.unsetcurrent instead of setcurrent with None

bmstore.write: use unsetcurrent instead of setcurrent with None

commands.bookmark: use unsetcurrent instead of setcurrent with None There are currently two different ways we can have no active bookmark: .hg/bookmarks.current being missing and it being an empty file. This patch and upcoming ones make an empty file the only way to represent no active bookmarks. This is the right choice because it matches the state that a new repository without bookmarks will be in.

strip: hold wlock for entire duration Previously, we'd acquire and release the wlock several times. This meant that other hg processes could come in and change state. Instead of that, retain the wlock for the entire duration of the strip.

bisect: report "both good and bad" as such, not as "not directly related"

phase: better error message when --force is needed When trying to turn a draft changeset into a secret changeset, I was told: % hg phase -s . cannot move 1 changesets to a more permissive phase, use --force no phases changed That message struck me as being backwards -- the secret phase feels less permissive to me since it restricts the changesets from being pushed. We don't use the word "permissive" elsewhere, 'hg help phase' talks about "lower phases" and "higher phases". I therefore reformulated the error message to be cannot move 1 changesets to a higher phase, use --force That is not perfect either, but more in line with the help text. An alternative could be cannot move phase backwards for 1 changesets, use --force which fits better with the help text for --force.
