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)
