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.

  $ hg init
  $ echo foo > a
  $ hg add a
  $ hg commit -m "1"

  $ echo bar > b
  $ hg add b
  $ hg remove a

Should show a removed and b added:

  $ hg status
  A b
  R a

  $ hg revert --all
  undeleting a
  forgetting b

Should show b unknown and a back to normal:

  $ hg status
  ? b

  $ rm b

  $ hg co -C 0
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo foo-a > a
  $ hg commit -m "2a"

  $ hg co -C 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo foo-b > a
  $ hg commit -m "2b"
  created new head

  $ HGMERGE=true hg merge 1
  merging a
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

Should show foo-b:

  $ cat a
  foo-b

  $ echo bar > b
  $ hg add b
  $ rm a
  $ hg remove a

Should show a removed and b added:

  $ hg status
  A b
  R a

Revert should fail:

  $ hg revert
  abort: uncommitted merge with no revision specified
  (use "hg update" or see "hg help revert")
  [255]

Revert should be ok now:

  $ hg revert -r2 --all
  undeleting a
  forgetting b

Should show b unknown and a marked modified (merged):

  $ hg status
  M a
  ? b

Should show foo-b:

  $ cat a
  foo-b
