Bug#758015: lintian: [new check] No SOVERSION in packages name, Policy 8.2

[Eric Maeker <eric.maeker@gmail.com>]

Package: lintian
Version: 2.5.10.4
Severity: wishlist

Dear Maintainer/DD/Mentors,

Based on Shared Librairies, Packaging Policy 8.2.

When the upstream source is not versionned (stable ABI),
the source package can be released without the SOVERSION.
In this case (source lib without version), lintian could 
check if all the package are correctly unversionned and 
raise a warning when it found a discordance.

Eg of an unversionned source package:
  libfoo -> libfoo{-dev,-dbg,-headers}  -> Ok (no version on all packages)
  libfoo -> libfoo, libfoo1{-dev,-dbg,-headers}  -> Wrong
  libfoo -> libfoo1, libfoo{-dev,-dbg,-headers}  -> Wrong

You can also read the following bugs #567510, #693911.

Thanks for your involvement in Debian.
Eric, Debian Med
