Subject: [PATCH] Python 2+3 version variable and test macros

**Variable Macros** (used in the below macros)
- `%python2_version%` returns **2.7** for Python 2.7.x
- `%python2_version%` returns **3.6** for Python 3.6.x

**Actionable Macros** (python unit tests)
`%python_test` and `%python3_test`

If the `PYTHONPATH` environment variable is not set, the macro will do it
The following cases are handled:

1. The macro is called without parameters -> use default test function
e.g.: `%python_test` -> `python setup.py test`

2. The macro is called with a python script (`.py`) as parameter -> execute the script with the specified version of python
e.g.: `%python3_test selftest.py -v` -> `python3 selftest.py -v`

3. The macro is called with something else as parameter -> execute the command "as it is"
e.g.: `%python_test py.test -k 'not this_test'` -> `py.test -k 'not this_test'`

The macros will look for the "standard" build directories `py2build` or `py3build` and be executed in the current directory if they can't find it, so they can also be used in packages build with autotools for example.
