branchmap: allow to use cache of subset

Filtered repository are *subset* of unfiltered repository. This means that a
filtered branchmap could be use to compute the unfiltered version.

And filtered version happen to be subset of each other:
- "all() - unserved()" is a subset of "all() - hidden()"
- "all() - hidden()" is a subset of "all()"

This means that branchmap with "unfiltered" filter can be used as a base for
"hidden" branchmap that itself could be used as a base for unfiltered
branchmap.

   unserved < hidden < None

This changeset implements this mechanism. If the on disk branchcache is not valid
we use the branchcache of the nearest subset as base instead of computing it from
scratch. Such fallback can be cascaded multiple time is necessary.

Note that both "hidden" and "unserved" set are a bit volatile. We will add more
stable filtering in next changesets.

This changeset enables collaboration between no filtering and "unserved"
filtering. Fixing performance regression introduced by 47f00b0de337

Let commit recurse into subrepos by default to match pre-2.0 behavior:

  $ echo "[ui]" >> $HGRCPATH
  $ echo "commitsubrepos = Yes" >> $HGRCPATH

  $ hg init t
  $ cd t

first revision, no sub

  $ echo a > a
  $ hg ci -Am0
  adding a

add first sub

  $ echo s = s > .hgsub
  $ hg add .hgsub
  $ hg init s
  $ echo a > s/a

Revert subrepo with no backup. The "reverting s/a" line is gone since
we're really running 'hg update' in the subrepo:

Test behavior of add for explicit path in subrepo:
  $ cd ..
  $ hg init explicit
  $ cd explicit
  $ echo s = s > .hgsub
  $ hg add .hgsub
  $ hg init s
  $ hg ci -m0
Adding with an explicit path in a subrepo adds the file
  $ echo c1 > f1
  $ echo c2 > s/f2
  $ hg st -S
  ? f1
  ? s/f2
  $ hg add s/f2
  $ hg st -S
  A s/f2
  ? f1
  $ hg ci -R s -m0
  $ hg ci -Am1
  adding f1
Adding with an explicit path in a subrepo with -S has the same behavior
  $ echo c3 > f3
  $ echo c4 > s/f4
  $ hg st -S
  ? f3
  ? s/f4
  $ hg add -S s/f4
  $ hg st -S
  A s/f4
  ? f3
  $ hg ci -R s -m1
  $ hg ci -Ama2
  adding f3
Adding without a path or pattern silently ignores subrepos
  $ echo c5 > f5
  $ echo c6 > s/f6
  $ echo c7 > s/f7
  $ hg st -S
  ? f5
  ? s/f6
  ? s/f7
  $ hg add
  adding f5
  $ hg st -S
  A f5
  ? s/f6
  ? s/f7
  $ hg ci -R s -Am2
  adding f6
  adding f7
  $ hg ci -m3
Adding without a path or pattern with -S also adds files in subrepos
  $ echo c8 > f8
  $ echo c9 > s/f9
  $ echo c10 > s/f10
  $ hg st -S
  ? f8
  ? s/f10
  ? s/f9
  $ hg add -S
  adding f8
  adding s/f10 (glob)
  adding s/f9 (glob)
  $ hg st -S
  A f8
  A s/f10
  A s/f9
  $ hg ci -R s -m3
  $ hg ci -m4
Adding with a pattern silently ignores subrepos
  $ echo c11 > fm11
  $ echo c12 > fn12
  $ echo c13 > s/fm13
  $ echo c14 > s/fn14
  $ hg st -S
  ? fm11
  ? fn12
  ? s/fm13
  ? s/fn14
  $ hg add 'glob:**fm*'
  adding fm11
  $ hg st -S
  A fm11
  ? fn12
  ? s/fm13
  ? s/fn14
  $ hg ci -R s -Am4
  adding fm13
  adding fn14
  $ hg ci -Am5
  adding fn12
Adding with a pattern with -S also adds matches in subrepos
  $ echo c15 > fm15
  $ echo c16 > fn16
  $ echo c17 > s/fm17
  $ echo c18 > s/fn18
  $ hg st -S
  ? fm15
  ? fn16
  ? s/fm17
  ? s/fn18
  $ hg add -S 'glob:**fm*'
  adding fm15
  adding s/fm17 (glob)
  $ hg st -S
  A fm15
  A s/fm17
  ? fn16
  ? s/fn18
  $ hg ci -R s -Am5
  adding fn18
  $ hg ci -Am6
  adding fn16

Test behavior of forget for explicit path in subrepo:
Forgetting an explicit path in a subrepo untracks the file
  $ echo c19 > s/f19
  $ hg add s/f19
  $ hg st -S
  A s/f19
  $ hg forget s/f19
  $ hg st -S
  ? s/f19
  $ rm s/f19
  $ cd ..
