We somewhat expected that all kdepimlibs4 users have only optional deps or
that they will switch to KF5 as well. Yes, we screwed up (again).

There is this tiny library called libakonadiprotocolinternals.so which Akonadi
server and kdepimlibs share. It contains some utility classes and macros
related to the communication protocol. The protocol has changed substantially
in Qt5-based Akonadi, thus the library API is no longer compatible with the
old one. However the library is called libKF5AkonadiPrivate.so in Akonadi 5,
so it's possible to co-install those two libraries. It's not possible to
however co-install the rest of Akonadi (akonadiserver, akonadictl, ....).
With my packager hat on, we will probably end up doing something like this in
akonadi-server-15.08 (whatever is in akonadi-15.08 tarball)
akonadi-server-devel-15.08 (headers for ^^)
akonadi-15.08 (whatever is kdepimlibs, Requires: akonadi-server)
akonadi-devel-15.08 (headers for ^^)
akonadi-server-compat-libs-1.13 (libakonadiprotocolinternals.so from
akonadi-server-compat-libs-devel-1.13 (headers for ^^)
akonadi-server-compat-1.13 (the rest of akonadi-1.13 tarball, Requires:
akonadi-server-compat-libs, Conflicts: akonadi-server >= 15.08)
kdepimlibs-4.14 (Requires: akonadi-server-compat-libs-devel = 1.13)
