Dear Fedora,

This breaks, for example, rsyslog-8.30.0-3, which was compiled against
libfastjson-0.99.7, but didn't go out together with it, so when I ran
dnf update, the set contained only new rsyslog, which, when run with
libfastjson-0.99.6 (same SONAME!) simply dies:
# rsyslogd -n
rsyslogd: symbol lookup error: rsyslogd: undefined symbol: fjson_global_do_case_sensitive_comparison
Dear maintainers, please use abipkgdiff when doing library updates.
Upstreams do break ABI without bumping SONAME sometimes.
I'm not sure if it is a real issue or not. A user in #fedora got bit by this where his rsyslog was upgraded but not his libfastjson. Updating to libfastjson-0.99.7 allowed rsyslog to startup and begin logging. But it appeared to die quickly. This happened at least twice.
There could be other things going on with his setup, but I thought I'd point out a potential issue to be on the lookout for even if the missing symbol has been resolved.
