Bug#538867: lintian: please add additional Python / dh check

[Bernd Zeimetz <bzed@debian.org>]

Package: lintian
Version: 2.2.13
Severity: wishlist

Hi Lintian maintainers,

since debhelper 7.3.5 dh is able to build extensions and debug packages,
so it makes sense to check for a proper dependency on debhelper to make
it more obvious that a specific version is needed. This makes
backporters' life a bit more easy at the end, I hope.

The new check should be implemented in the following way:

If the package builds public Python extentions
       [ `find /usr/lib/pyshared/ -type f -name '*.so' | wc -l` -gt 0 ]
    _or_ the package build-depends on python.*-dbg (needs to match
       pythonX.Y-dbg, python-dbg, python-all-dbg)
_and_ the package uses dh in debian/rules
_and_ setup.py exists in the sourcedirectory (check if dh is called with
      --sourcedirectory
   _or_ dh is called with --buildsystem=python_distutils

then we need debhelper >= 7.3.5.


Thanks and cheers,

Bernd
