simplemerge: move conflict warning message to filemerge

The current output for a failed merge with conflict markers looks something like:

  merging foo
  warning: conflicts during merge.
  merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
  merging bar
  warning: conflicts during merge.
  merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')

We're going to change the way merges are done to perform all premerges before
all merges, so that the output above would look like:

  merging foo
  merging bar
  warning: conflicts during merge.
  merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
  warning: conflicts during merge.
  merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')

The 'warning: conflicts during merge' line has no context, so is pretty
confusing.

This patch will change the future output to:

  merging foo
  merging bar
  warning: conflicts while merging foo! (edit, then use 'hg resolve --mark')
  warning: conflicts while merging bar! (edit, then use 'hg resolve --mark')

The hint on how to resolve the conflicts makes this a bit unwieldy, but solving
that is tricky because we already hint that people run 'hg resolve' to retry
unresolved merges. The 'hg resolve --mark' mostly applies to conflict marker
based resolution.
