context: avoid writing outdated dirstate out (issue5584)

Before this patch, workingctx.status() may cause writing outdated
dirstate out, if:

  - .hg/dirstate is changed simultaneously after last loading it,
  - there is any file, which should be dirstate.normal()-ed

Typical issue case is:

  - the working directory is updated by "hg update"
  - .hg/dirstate is updated in background (e.g. fsmonitor)

This patch compares identities of dirstate before and after
acquisition of wlock, and avoids writing outdated dirstate out, if
change of .hg/dirstate is detected.
