silent ABI break in c5145b6816b1a771daa8c0282c34bd303a360f56

https://github.com/rpm-software-management/hawkey/commit/c5145b6816b1a771daa8c0282c34bd303a360f56 is a silent ABI break - new values were added into the middle of an enumeration.
This broke libhif, which in turn broke rpm-ostree, which in turn broke Fedora updates-testing composes.
In the end, it's not a big deal, we'll just rebuild libhif.
However, this cost quite a bit of debugging time from multiple people.
dnf-1.0.2-2.fc22, hawkey-0.5.9-2.fc22, libhif-0.2.0-6.fc22 has been submitted as an update for Fedora 22.
OMG, I cannot believe that we did it again...
The enum ABI change seems to affect PackageKit as well, not just libhif. I wonder if it would make sense to fix the ABI break in hawkey instead of rebuilding all the consumers?
PackageKit links directly to hawkey as well as using it through libhif and uses the affected enum where the ABI changed.
Avoiding the ABI changes seems a bit safer since it allows using newer hawkey together with older consumers -- a broken dep or whatever could possibly result in a partial system upgrade where a consumer is kept back and only hawkey is updated.

I thought I was supposed to be given the heads up on new librepo + hawkey releases? There was no "We're about to release..." or release announcement on email@example.com and I had no idea about the new release until Kalev pointed me at this bug.
Sorry for that break and thanks for fixing it.
