Attempt at creating a python3-cairo-dbg package in Debian

When developing a Gtk app in Python, it's useful to be able to debug segfaults taking place in the C backend. The Python backtrace provided by gdb is pretty useless unless the debug packages are installed, for example: https://packages.debian.org/search?keywords=python3-dbg Without the debug packages, useful info like the method names are "optimized out" and are not displayed.

In Debian, debugging Gtk apps with python3-dbg does not seem to be possible because there is no debug version of python3-cairo. For example, there is a debug version of python-cairo called python-cairo-dbg, but there is no python3-cairo-dbg for python3-cairo.

I poked about this in oftc.net #debian-python and I was told:
<p1otr> add binary package in debian/control, add python3-all-dbg to Build-Depends and if you use pybuild, that's all
<p1otr> my first try was: 315465 but then I realized it's waf so I give up, life is too short for waf
<p1otr> (if you want to continue: the problem is with waf using some options from dbg interpreter and some from regular one, f.e. it calls pythnon3.5-config instead of python3.5-dbg-config)

See the attachment for the attempt at creating python3-cairo-dbg.

This is probably more a Debian bug than pycairo, but assigning to the pycairo project since it's definitely not a core Cairo issue.

However I think pycairo may be a bit moribund presently, so you'll likely have better luck interfacing with Debian on this.

Looks like there is a python3-cairo-dbgsym in the Debian debug repos now.
