Fix debian packaging
Renaming libsbjson2.3-dev to libsbjson-dev resolves conflict with the official distribution package.
Adding libldap2-dev dependency solves FTBFS when building SOGo in a clean chroot environment (pbuilder). Include files in libsope-ldap-dev require the include files from libldap2-dev. Therefore I consider it right that libldap2-dev should be listed as a dependency in libsope-ldap-dev.
Maybe I'm wrong but how far I understand the packaging for the libsbjson is not even required because it is in the all main debian/ubuntu stable releases (from wheezy in debian and from trusty in ubuntu). It also looks like just a repackaging of the official libsbjson, I could not find anything that shows it compile it.
Inverse branch of SBJson contains one commit that addresses crash if result is NSNull. See: https://github.com/inverse-inc/sope/commit/45339ab1da6d8c87f17c113392fbc455cead6dee
Added commit 3850f3f, which allows to build on Debian Stretch.
Is there something I could have done to be able to merge the proposed changes?
I accepted, but even the recheck does not pick it up :( I saw already accepted if I go again... something wrong with the integration
