largefiles: use "normallookup" on "lfdirstate" while reverting

Before this patch, largefiles gotten from revisions other than the
parent of the working directory at "hg revert" become "clean"
unexpectedly in steps below:

    1. "repo.status()" is invoked (for status check before reverting)
      1-1 "dirstate" entry for standinfile SF is "normal"-ed
     (1-2 "lfdirstate" entry of largefile LF (for SF) is "normal"-ed)

    2. "cmdutil.revert()" is invoked
      2-1 standinfile SF is updated in the working directory
      2-2 "dirstate" entry for SF is NOT updated

    3. "lfcommands.updatelfiles()" is invoked (by "overrides.overriderevert()")
      3-1 largefile LF (for SF) is updated in the working directory
      3-2 "dirstate" returns "n" and valid timestamp for SF (by 1-1 and 2-2)
      3-3 "lfdirstate" entry for LF is "normal"-ed
      3-4 "lfdirstate" is written into ".hg/largefiles/dirstate", and
          timestamp of LF is stored into "lfdirstate" file (by 3-3)
          (ASSUMPTION: timestamp of LF differs from one of "lfdirstate" file)

Then, "hs status" treats LF as "clean", even though LF is updated by
"other" revision (by 3-1), because "lfilesrepo.status()" always treats
"normal"-ed files (by 3-3 and 3-4) as "clean".

When largefiles are reverted, they should be "normallookup"-ed
forcibly.

This patch uses "normallookup" on "lfdirstate" while reverting, by
passing "True" to newly added argument "normallookup".

Forcible "normallookup"-ing is not so expensive, because list of
target largefiles is explicitly specified in this case.

This patch uses "[debug] dirstate.delaywrite" feature in the test, to
ensure that timestamp of the largefile gotten from "other" revision is
stored into ".hg/largefiles/dirstate" (for ASSUMPTION at 3-4)

This file focuses mainly on updating largefiles in the working
directory (and ".hg/largefiles/dirstate")
