largefiles: use 'remote'/'local' in merge prompts like in other merge prompts

Prompts like
  foo has been turned into a largefile
  use (l)argefile or keep as (n)ormal file?
was not as clear as the usual prompts that use 'remote' or 'local' to explain
what happened on which side ... especially not when used to the normal prompts.

"as" could also indicate that it would be possible to take the content of the
largefile and somehow put it into the normal file. It could make it more clear
that it was a choice between one side or the other.

For consistency we will now phrase it like:
  remote turned local normal file f into a largefile
  use (l)argefile or keep (n)ormal file?

       clones. In particular, if two shared clones are both updated to
       the same changeset, and one of them destroys that changeset
       with rollback, the other clone will suddenly stop working: all
       operations will fail with "abort: working directory has unknown

       the broken clone to reset it to a changeset that still exists.
