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.
