hg-core: add fncache module

For now it's only a super simple trait. It will be used for calling back into
Python soon, and later will be fleshed out into a full fncache.

Hidden common predecessor of divergence does not cause crash

First create C1 as a pruned successor of C
  $ hg co C
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg amend -m C1
  $ hg tag --local C1
  $ hg debugobsolete $(hg log -T '{node}' -r C1)
  1 new obsolescence markers
  obsoleted 1 changesets
Now create C2 as other side of divergence (not actually divergent because C1 is
pruned)
  $ hg co C
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg amend -m C2
  1 new orphan changesets
Make the common predecessor (C) pruned
  $ hg tag --local --remove C
  $ hg co C1
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
Try to cause divergence
  $ hg amend -m C11
  abort: cannot amend 2758767f5d17, as that creates content-divergence with bfcb433a0dea, from 26805aba1e60

Corner case of amend from issue6157:
- working copy parent has a change to file `a`
- working copy has the inverse change
- we amend the working copy parent for files other than `a`
hg used to include the changes to `a` anyway.
