copies: refactor checkcopies() into a top level method...

copies: refactor checkcopies() into a top level method This moves checkcopies() out of mergecopies() and makes it a top level function in the copies module. This allows extensions to override it. For example, I'm developing a filelog replacement that doesn't have rev numbers so all the rev number dependent implementation here needs to be replaced by the extension. No logic is changed in this commit.
