I'm about to embark on once again syncing changes fromzipp tozipfile.

Historically, I've manually copied the contents of thecpython branch to the relevant files in this repository, but that process is error prone (because it involves syncing a whole file to a portion of another file).

I'd like to instead create packages forzipfile andtest_zipfile, such that the functionality that's synced withzipp can be kept separate from other zipfile functionality. Moreover, late versions ofzipp bring in extra dependencies so a package can also serve as a home to vendor such functionality.

I'm not suggesting to change the user's signature at all. The names will still be presented through thezipfile module unchanged.
