bookmarks: explicitly track identical bookmarks

bookmarks.compare() previously lumped identical bookmarks in the
"invalid" bucket. This patch adds a "same" bucket.

An 8-tuple for holding this state is pretty gnarly. The return value
should probably be converted into a class to increase readability. But
that is beyond the scope of a patch intended to be a late arrival to
stable.

#require serve fifo

Test hangup signal in the middle of transaction

  $ hg init
  $ mkfifo p
  $ hg serve --stdio < p 1>out 2>&1 &
  $ P=$!

Do test while holding fifo open
