largefiles: update standins only at the 1st commit of "hg rebase --continue"

Before this patch, "hg rebase --continue" may record incorrect
standins, because largefiles extension always avoid updating standins
while rebasing, even though largefiles in the working directory may be
modified manually at the 1st commit of "hg rebase --continue".

But, on the other hand, updating standins should be avoided at
subsequent commits for efficiency reason.

To update standins only at the 1st commit of "hg rebase --continue",
this patch introduces state-full callable object
"automatedcommithook", which updates standins by
"lfutil.updatestandinsbymatch()" only at the 1st commit of resuming.

Even after this patch, "repo._isrebasing = True" is still needed to
avoid some status report while updating largefiles in
"lfcommands.updatelfiles()".

This is reason why this patch omits not "repo._isrebasing = True" in
"overriderebase" but examination of "getattr(repo, "_isrebasing",
False)" in "updatestandinsbymatch".
