largefiles: send statlfile remote calls only for nonexisting locally files

Files that are already in local store should be checked locally. The problem
with this implementation is how difference in messages between local and remote
checks should look like. For now local errors for file missing and content
corrupted looks like this:

'changeset cset: filename references missing storepath\n'
'changeset cset: filename references corrupted storepath\n'

for remote it looks like:

'changeset cset: filename missing\n'
'changeset cset: filename: contents differ\n'

Contents differ error for remote calls is never raised currently - for now
statlfile implementation lacks checking file content.

#require serve

the status call is to check for issue5130

  $ hg init server
  $ cd server

  $ hg -q commit -A -m initial
  >>> for i in range(1024):
  ...     with open(str(i), 'wb') as fh:

  $ hg -q commit -A -m 'add a lot of files'
  $ hg st
  $ hg serve -p $HGPORT -d --pid-file=hg.pid

Stream clone while repo is changing:

  $ mkdir changing
  $ cd changing

extension for delaying the server process so we reliably can modify the repo
while cloning

  $ cat > delayer.py <<EOF
  > import time
  > from mercurial import extensions, scmutil
  > def __call__(orig, self, path, *args, **kwargs):
  >     if path == 'data/f1.i':
  >         time.sleep(2)
  >     return orig(self, path, *args, **kwargs)
  > extensions.wrapfunction(scmutil.vfs, '__call__', __call__)
  > EOF

prepare repo with small and big file to cover both code paths in emitrevlogdata

  $ hg init repo
  $ touch repo/f1
  $ $TESTDIR/seq.py 50000 > repo/f2
  $ hg -R repo ci -Aqm "0"
  $ hg -R repo serve -p $HGPORT1 -d --pid-file=hg.pid --config extensions.delayer=delayer.py
  $ cat hg.pid >> $DAEMON_PIDS

clone while modifying the repo between stating file with write lock and
actually serving file content

  $ hg clone -q --uncompressed -U http://localhost:$HGPORT1 clone &
  $ sleep 1
  $ echo >> repo/f1
  $ echo >> repo/f2
  $ hg -R repo ci -m "1"
  $ wait
  $ hg -R clone id
