bookmarks: don't use bookmarks.listbookmarks in local computations

bookmarks.listbookmarks is for wire-protocol use. The normal way to get
all the bookmarks on a local repository is repo._bookmarks.

Test hangup signal in the middle of transaction

  $ "$TESTDIR/hghave" serve fifo || exit 80
  $ hg init
  $ mkfifo p
  $ hg serve --stdio < p 1>out 2>&1 &
  $ P=$!

Do test while holding fifo open

  $ (
  > echo lock
  > echo addchangegroup
  > while [ ! -s .hg/store/journal ]; do sleep 0; done
  > kill -HUP $P
  > ) > p
