localrepo: put bookmark move following commit in one transaction Before this patch, making a commit on a local repo could move a bookmark and both operations would not be grouped as one transaction. This patch makes both operations part of one transaction. This is necessary to switch to the new api to save bookmarks repo._bookmarks.recordchange if we don't want to change the current behavior of rollback. Dirstate change happening after the commit is done is now part of the transaction mentioned above. This leads to a change in the expected output of several tests. The change to test-fncache happens because both lock are now released in the same finally clause. The lock release is made explicitly buggy in this test. Previously releasing lock would crash triggering release of wlock that crashes too. Now lock release crash does not directly result in the release of wlock. Instead wlock is released at garbage collection time and the error raised at that time "confuses" python.
