merge: refactor code to advise fsmonitor in separate function

merge.update() is quite hard to understand, found this an easy win.

The end goal is to have better organized merge and mergestate handling and then
fix some related bugs.

foo was clean:

Trying to copy on top of an existing file fails,
  $ hg copy -A bar foo
  foo: not overwriting - file already committed
  ('hg copy --after --force' to replace the file by recording a copy)
  [1]
same error without the --after, so the user doesn't have to go through
two hints:
  $ hg copy bar foo
  foo: not overwriting - file already committed
  ('hg copy --force' to replace the file by recording a copy)
  [1]
but it's considered modified after a copy --after --force
  $ hg copy -Af bar foo

The hint for a file that exists but is not in file history doesn't
mention --force:

  xyzzy: not overwriting - file exists
  ('hg copy --after' to record the copy)
