fsmonitor: use vfs instead of opener (issue5938)

"opener" of localrepository object was dropped at Mercurial 4.3 (or
a7e210167c28). "vfs" should be used instead.

wlock is required to write into a file under .hg directory.

For efficiency, we should change _cmpsets() from:

  1. acquire wlock
  2. open log file under .hg directory with write mode
  3. compare between result of watchman and Mercurial's dirstate logic
  4. write out error info into a file, if error is detected
  5. release wlock

to:

  1. compare between result of watchman and Mercurial's dirstate logic
  2. acquire wlock, if error is detected
  3. open and write error info into a file
  4. release wlock

But this is another issue.

#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
