largefiles: ignore removal status of files not managed in the target context
Before this patch, "hg status --rev REV" listed largefiles removed in
the working directory up with "R" mark, even if they aren't managed in
the REV. Normal files aren't listed up in such case.
When "lfilesrepo.status" is invoked for "hg status --rev REV", it
treats files on conditions below as "removed" (to avoid manifest full
scan in "ctx.status" ?):
- marked as "R" in lfdirstate, or
- files managed in the target revision but unknown in the manifest
of the working context (= not including "R" files)
But the former can include files not managed in the target context.
To ignore removal status of files not managed in the target context,
this patch drops files unknown in the target revision from "removed"
list.

'''measure performance of Mercurial commands
Using ``hgperf`` instead of ``hg`` measures performance of the target
Mercurial command. For example, the execution below measures
performance of :hg:`heads --topo`::
$ hgperf heads --topo
All command output via ``ui`` is suppressed, and just measurement
result is displayed: see also "perf" extension in "contrib".
Costs of processing before dispatching to the command function like
below are not measured::
- parsing command line (e.g. option validity check)
- reading configuration files in
But ``pre-`` and ``post-`` hook invocation for the target command is
measured, even though these are invoked before or after dispatching to
the command function, because these may be required to repeat
execution of the target command correctly.
