largefiles: move "updatestandin" invocation to "hg.updaterepo" wrapper
Code paths below expect "hg.updaterepo" (or "hg.update" using it) to
execute linear merging:
- "update" in commands
- "postincoming" in commands, used for:
- "hg pull --update"
- "hg unbundle --update"
- "hgsubrepo.get" in subrepo
For linear merging with largefiles, standins should be updated
according to (possibly dirty) largefiles before "merge.update"
invocation to detect conflicts correctly.
Before this patch, only the "update" command can execute linear merging
correctly, because largefiles extension takes care of only it.
This patch moves "updatestandin" invocation from "overrideupdate" ("hg
update" wrapper) to "_hgupdaterepo" ("hg.updaterepo" wrapper) to
execute linear merging in "hg.updaterepo" correctly.
This is also a preparation to centralize the logic of updating
largefiles in the working directory into the function wrapping
"merge.update" in the subsequent patch.
