2) have `create_main_parser` mark the parser as the 'main' parser.
3) remove an extraneus block that's never called. thanks @netspyer.
4) move 'create_main_parser` to __init__ to avoid circular or embedded imports.
Previously pip was always installed directly from the source tree
however this causes concurrency issues so it is now copied into
the temporary directory and installed from there.
The `pip` executable was returning a successful status code (`0`) when
trying to install new packages with existing previous build directories.

* Move virtualenv creation out of TestPipEnvironment
* Remove global state and force explicit use of TestPipEnvironment
instances
* Remove "backup" virtualenv copying and instead create new
virtual environments each time.
* Remove the monkeypatched "PyPICache" functionality
* Remove things that were not being used anymore and were dead
weight
* Remove sitecustomize support which was primarily used to
monkeypatch the "PyPICache" but was used in one or two other
tests.
* Better output with the bare asserts we use throughout the tests
* Function fixtures are pretty nice, especially as a way to
start a background server or create an isolated virtualenv
* PEP381 Mirroring support was never fully implemented leaving
users of it trivially exploitable to a MITM or malicious mirror
operator.
* 2 out of 6 of the mirrors have been removed from the pool and
will never resolve.
* The remaining mirrors often fall behind
* The mirrors will likely never be available under HTTPS
* People who wish to use a mirror of PyPI can still do so by
manually specifying a mirror url for --index-url or
--extra-index-url which is more flexible, allowing for
mirrors to be hosted under any domain.
* develop:
add back in old tox.ini
add back test lost in the restructure
more functional/unit tests restructure
break up tests dir into data, unit tests, and functional tests
