Update Sphinx

- Repocopy textproc/py-sphinx to textproc/py-sphinx18

  Update it to 1.8.5 (latest version from 1.8.X).
  This version supports Python 2 and 3.
  Add test target.

- textproc/py-sphinx: Update to 3.0.2

  Python 3 only (3.5+).
  Add test target.

- Mk/Uses/python.mk: Add PY_SPHINX

  Shared macro to use with flavors and not break
  ports with USES=python (all versions).

  Python >=3.5  --> textproc/py-sphinx (v3.0.2)
  Python < 3.5  --> textproc/py-sphinx18 (v1.8.5)

  All ports that uses sphinx were changed to use the new variable
  ${PY_SPHINX} in the dependency line, exceptions:

    * Ports that fails to build with sphinx 3.0.2 because of code.
      They are pointing to textproc/py-sphinx18 directly.
      There aren't many ports.

    * Ports that doesn't know Python flavors.

- Add several patches to fix Sphinx consumers

  The most common issues are related with pkg-plist, the output
  files from Sphinx changes between versions, keep this dynamically
  is the better approach.

  This will save time in future sphinx updates.
