Jeremy Stanley 949c47c979 Avoid recursive calls into SetupTools entrypoint
Add a check in pbr.core.pbr() to make sure it hasn't already run,
and return immediately if it has. This replaces the earlier attempt
at loop-busting by setting the entrypoint to None in the dist, in
order to support PEP 517 builds without setup_requires.

Also test that pbr.json is now included in the dist tree, in order
to avoid future regressions.

PBR is a library that injects some useful and sensible default behaviors into your setuptools run. It started off life as the chunks of code that were copied between all of the OpenStack projects. Around the time that OpenStack hit 18 different projects each with at least 3 active branches, it seemed like a good time to make that code into a proper reusable library.

PBR is only mildly configurable. The basic idea is that there's a decent way to run things and if you do, you should reap the rewards, because then it's simple and repeatable. If you want to do things differently, cool! But you've already got the power of Python at your fingertips, so you don't really need PBR.

PBR builds on top of the work that d2to1 started to provide for declarative configuration. d2to1 is itself an implementation of the ideas behind distutils2. Although distutils2 is now abandoned in favor of work towards PEP 426 and Metadata 2.0, declarative config is still a great idea and specifically important in trying to distribute setup code as a library when that library itself will alter how the setup is processed. As Metadata 2.0 and other modern Python packaging PEPs come out, PBR aims to support them as quickly as possible.
