    version in EPEL7

---

  - Build Python 3 version(s) of gevent plugin on Fedora and
    EPEL7

  - Build Python 3 version of greenlet plugin on Fedora and
    EPEL7

  - Build Python 2 version of greenlet plugin on EPEL7

  - Always build Python 3 version of tornado plugin when
    building with Python 3 (drop python3_tornado build
    conditional)

  - Use /var/run/uwsgi when not using systemd

  - Build with versioned python command

  - Remove %%config from systemd unit file
