cmdutil: reimplement finddate() without using walkchangerevs()
It's simpler and slightly faster maybe because a fewer Python ops would
run.
Unscientific benchmark:
$ python -m timeit \
-s 'from mercurial import hg, ui, cmdutil; repo = hg.repository(ui.ui())' \
'cmdutil.finddate(repo.ui, repo, "<2008-01-01")'
(orig) 10 loops, best of 3: 1.45 sec per loop
(new) 10 loops, best of 3: 1.25 sec per loop
Now "hg churn" and "hg grep" are the only users of walkchangerevs(), which
I want to refactor and fix bugs.
test-simple-update: add test for -d DATE option
I couldn't find any tests for cmdutil.finddate() except for the abort case.
largefiles: walk history in ascending order while downloading all lfiles
I don't think the order matters. Maybe it's purely because of the use of
walkchangerevs(), which was originally designed for "hg log" command.
Surprisingly, the number of objects fetched in test-largefiles.t has changed.
According to the --verbose output, the order of the following fetches flipped
and the latter got deduplicated.

largefiles: replace use of walkchangerevs() with simple revset query
Since it does nothing in prepare(), what we're doing is just walking
revisions matching ".hglf" in reverse order.
largefiles: remove unused 'rev' parameter from downloadlfiles()
It's no longer used since

--all-largefiles as a special case of --lfrev."
