Bug#693911: lintian: Add check for library debug packages w/o SOVERSION in name

[Guillem Jover <guillem@debian.org>]

Package: lintian
Version: 2.5.10.2
Severity: wishlist
X-Debbugs-Cc: Ron Lee <ron@debian.org>

Hi!

If a debug library packages (containing only shared libraries, not a
conglomerated debug package) does not include the SOVERSION in its
name, it makes it not possible to co-install different debug packages
matching the SOVERSIONs of the corresponding library package, and
as such debug different version of the library at the same time,
when those should really be co-installable path-wise, as in:

  libfoo0
  libfoo1
  libfoo-dbg

Please add a check that emits a warning in such cases.

Thanks,
Guillem
