Bug#700776: libexosip2-dev: Dependency on lobosip-dev most likely needs to be versioned

[Jonas Smedegaard]

Package: libexosip2-dev
Version: 4.0.0-2
Severity: important

libexosip2-dev depends unversioned against libosip-dev.

Not sure, but it is highly likely that dependency should be versioned at
least against major version of osip API, like this:

  Build-depends: libosip2-dev (>= 4)
