sparse: refactor update actions filtering and call from core

merge.calculateupdates() now filters the update actions through sparse
by default.

The filtering no-ops if sparse isn't enabled or no sparse config
is defined.

The function has been refactored to behave more like a filter
instead of a wrapper of merge.calculateupdates().

We should arguably take sparse into account earlier in
merge.calculateupdates(). This patch preserves the old behavior
of applying sparse at the end of update calculation, which is the
simplest and safest approach.

  $ hg init

  $ echo a > a
  $ hg ci -qAm 'add a'

  $ hg init subrepo
  $ echo 'subrepo = http://example.net/libfoo' > .hgsub
  $ hg ci -qAm 'added subrepo'

  $ hg up -qC 0
  $ echo ax > a
  $ hg ci -m 'changed a'
  created new head

  $ hg up -qC 1
  $ cd subrepo
  $ echo b > b
  $ hg add b
  $ cd ..

Should fail, since there are added files to subrepo:

  $ hg merge
  abort: uncommitted changes in subrepository 'subrepo'
  [255]

Deleted files trigger a '+' marker in top level repos.  Deleted files are also
noticed by `update --check` in the top level repo.

  $ hg ci -Sqm 'add b'
  $ rm a
  $ hg id
  cb66ec850af7+ tip
  $ hg sum
  parent: 3:cb66ec850af7 tip
   add b
  branch: default
  commit: 1 deleted (clean)
  update: 1 new changesets, 2 branch heads (merge)
  phases: 4 draft

  $ hg up --check -r '.^'
  abort: uncommitted changes
  [255]
  $ hg st -S
  ! a
  $ hg up -Cq .

Test that dirty is consistent through subrepos

  $ rm subrepo/b

TODO: a deleted subrepo file should be flagged as dirty, like the top level repo

  $ hg id
  cb66ec850af7 tip

TODO: a deleted file should be listed as such, like the top level repo

  $ hg sum
  parent: 3:cb66ec850af7 tip
   add b
  branch: default
  commit: (clean)
  update: 1 new changesets, 2 branch heads (merge)
  phases: 4 draft

Modified subrepo files are noticed by `update --check` and `summary`

  $ echo mod > subrepo/b
  $ hg st -S
  M subrepo/b

  $ hg up -r '.^' --check
  abort: uncommitted changes in subrepository 'subrepo'
  [255]

  $ hg sum
  parent: 3:cb66ec850af7 tip
   add b
  branch: default
  commit: 1 subrepos
  update: 1 new changesets, 2 branch heads (merge)
  phases: 4 draft

TODO: why is -R needed here?  If it's because the subrepo is treated as a
discrete unit, then this should probably warn or something.
  $ hg revert -R subrepo --no-backup subrepo/b -r .

  $ rm subrepo/b
  $ hg st -S
  ! subrepo/b

TODO: --check should notice a subrepo with a missing file.  It already notices
a modified file.

  $ hg up -r '.^' --check
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

TODO: update without --clean shouldn't restore a deleted subrepo file, since it
doesn't restore a deleted top level repo file.
  $ hg st -S

  $ hg bookmark -r tip @other
  $ echo xyz > subrepo/c
  $ hg ci -SAm 'add c'
  adding subrepo/c
  committing subrepository subrepo
  created new head
  $ rm subrepo/c

Merge sees deleted subrepo files as an uncommitted change

  $ hg merge @other
   subrepository subrepo diverged (local revision: 2b4750dcc93f, remote revision: cde40f86152f)
  (M)erge, keep (l)ocal [working copy] or keep (r)emote [merge rev]? m
  abort: uncommitted changes (in subrepo subrepo)
  (use 'hg status' to list changes)
