largefiles: for update -C, only update largefiles when necessary

Before, a --clean update with largefiles would use the "optimization" that it
didn't read hashes from standin files before and after the update. Instead of
trusting the content of the standin files, it would rehash all the actual
largefiles that lfdirstate reported clean and update the standins that didn't
have the expected content. It could thus in some "impossible" situations
automatically recover from some "largefile got out sync with its standin"
issues (even there apparently still were weird corner cases where it could
fail). This extra checking is similar to what core --clean intentionally do
not do, and it made update --clean unbearable slow.

Usually in core Mercurial, --clean will rely on the dirstate to find the files
it should update. (It is thus intentionally possible (when trying to trick the
system or if there should be bugs) to end up in situations where --clean not
will restore the working directory content correctly.) Checking every file when
we "know" it is ok is however not an option - that would be too slow.

Instead, trust the content of the standin files. Use the same logic for --clean
as for linear updates and trust the dirstate and that our "logic" will keep
them in sync. It is much cheaper to just rehash the largefiles reported dirty
by a status walk and read all standins than to hash largefiles.

Most of the changes are just a change of indentation now when the different
kinds of updates no longer are handled that differently. Standins for added
files are however only written when doing a normal update, while deleted and
removed files only will be updated for --clean updates.

Preparing the subrepository 'sub2'

  $ hg init sub2
  $ echo sub2 > sub2/sub2
  $ hg add -R sub2
  adding sub2/sub2 (glob)
  $ hg commit -R sub2 -m "sub2 import"

Preparing the 'sub1' repo which depends on the subrepo 'sub2'

  $ hg init sub1
  $ echo sub1 > sub1/sub1
  $ echo "sub2 = ../sub2" > sub1/.hgsub
  $ hg clone sub2 sub1/sub2
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R sub1
  adding sub1/.hgsub (glob)
  adding sub1/sub1 (glob)
  $ hg commit -R sub1 -m "sub1 import"

Preparing the 'main' repo which depends on the subrepo 'sub1'

  $ hg init main
  $ echo main > main/main
  $ echo "sub1 = ../sub1" > main/.hgsub
  $ hg clone sub1 main/sub1
  updating to branch default
  cloning subrepo sub2 from $TESTTMP/sub2
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R main
  adding main/.hgsub (glob)
  adding main/main (glob)
  $ hg commit -R main -m "main import"

Cleaning both repositories, just as a clone -U

  $ hg up -C -R sub2 null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg up -C -R sub1 null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg up -C -R main null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ rm -rf main/sub1
  $ rm -rf sub1/sub2

Clone main

  $ hg --config extensions.largefiles= clone main cloned
  updating to branch default
  cloning subrepo sub1 from $TESTTMP/sub1
  cloning subrepo sub1/sub2 from $TESTTMP/sub2 (glob)
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

Largefiles is NOT enabled in the clone if the source repo doesn't require it
  $ cat cloned/.hg/hgrc
  # example repository config (see "hg help config" for more info)
  [paths]
  default = $TESTTMP/main (glob)
  
  # path aliases to other clones of this repo in URLs or filesystem paths
  # (see "hg help config.paths" for more info)
  #
  # default-push = ssh://[e-mail]/hg/jdoes-fork
  # my-fork      = ssh://[e-mail]/hg/jdoes-fork
  # my-clone     = /home/jdoe/jdoes-clone

  # name and email (local to this repository, optional), e.g.
  # username = Jane Doe <[e-mail]>
