The following patch resolves the app_python3 build errors (Which are changes with Python
3.7). Fedora 29 includes Python 3.7 released on 06/27/2018.

@amessina - just make a pull request for the patch, it is easier to merge, thanks!

@miconda ok, I'll need to figure out how to do that ;)
I also need to figure out how to do `if Python >=3.7` since these warnings come from
changes with the Python 3.7 release. I'm sure some stable enterprise-type distros
might not yet be using 3.7.

@amessina - I see that you can get the version numbers via defines, for example header
files for python 3.5.3 has the following defines:
```
#define PY_MAJOR_VERSION 3
#define PY_MINOR_VERSION 5
#define PY_MICRO_VERSION 3
```
So you can have:
```
#if PY_MAJOR_VERSION >= 3 && PY_MINOR_VERSION >= 7
...
#endif
```

Ok @miconda, I think I learned how to do all the Github related stuff and went with the
`#if PY_VERSION_HEX >= 0x03070000` style of version checking based on
https://docs.python.org/3/c-api/apiabiversion.html
While this patch "fixes" the Python3.7 deprecation warnings, I don't know
how the project overall likes to handle things like this. I'm guessing that true devs
would prefer to NOT litter code with `#if #endif` statements, but that's for you guys
to decide.
Thank you for letting me try to contribute.

I don't know how the project overall likes to
handle things like this. I'm guessing that true devs would
prefer to NOT litter code with #if #endif statements, but that's for you guys to
decide.
There is no general policy against #if pre-processor statements in the code. Sure, we try
to avoid them if possible. But in this particular case where its necessary to ensure
compatibility with different libraries, it is of course fine. This is used also in other
modules.
Lets wait a bit if Daniel has some comments on the referenced pull request. Otherwise I
can also merge it, for me it looks fine.

The referenced patch was merged a while ago, so I guess this one can be closed, if still
something to do, reopen or create a new one.
