fastannotate: process files as they arrive

peer.commandexecutor()'s context manager waits for all responses to
arrive in its __exit__() method. We want to process the results as
they arrive, so we should do that inside the context manager
scope. Note that the futures' result() methods have been replaced to
make sure that the command executor's sendcommands() method is called
when the first future's result is requested, so we don't need to do
that.

A minor side-effect is that we can no longer easily tell when the
server has started sending us responses, so that long statement was
lost.

#require bzr

N.B. bzr 1.13 has a bug that breaks this test.  If you see this
test fail, check your bzr version.  Upgrading to bzr 1.13.1
should fix it.

BUG: file-branch2 should not be added in rev 4, and the rename_me -> renamed
move should be recorded in the fixup merge.

nothing should be outgoing

BUG(?): The move seems to be recorded in rev 4, so it should probably show up
there.  It's not recorded as a move in rev 5, even in source-hg.
