rust-revlog: add invalidation detection to `NodeTree` class

This will be useful for callers, such as `scmutil` who reuse a
`NodeTree` instance as a cache. They would otherwise get hard
errors if any mutation of the index occurred since instantiation.

This is something the C index does not provide.

Rebase - try to rebase on an applied mq patch:

  $ hg rebase -s 1 -d 3
  abort: cannot rebase onto an applied mq patch
  [20]

Rebase - same thing, but mq patch is default dest:

  $ hg up -q 1
  $ hg rebase
  abort: cannot rebase onto an applied mq patch
  [20]
  $ hg up -q qtip

Rebase - generate a conflict:

  $ hg rebase -s 2 -d 1
  rebasing 2:3504f44bffc0 f.patch qbase "P0"
  merging f
  warning: conflicts while merging f! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see 'hg resolve', then 'hg rebase --continue')
  [240]

Fix the 1st conflict:

  $ echo mq1r1 > f
  $ hg resolve -m f
  (no more unresolved files)
  continue: hg rebase --continue
  $ hg rebase -c
  rebasing 2:3504f44bffc0 f.patch qbase "P0"

  merging f
  warning: conflicts while merging f! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see 'hg resolve', then 'hg rebase --continue')
  [240]

Fix the 2nd conflict:

  $ echo mq1r1mq2 > f
  $ hg resolve -m f
  (no more unresolved files)
  continue: hg rebase --continue
  $ hg rebase -c
