Version 1.15.0 compatible with libunbound.so.2, is it good idea?

[Petr Menšík]

Hi,

We have request [1] to rebase unbound to recent version on RHEL8. So I
dug into the code and found relatively simple way to keep ABI unchanged
and compatible with version 1.7.3, which is still there. It allows
upgrading to unbound 1.15.0 without the need to recompile depending
binaries. Or at least it seems so.

Would you review the change [2], whether it creates possible
regressions? Do you think it might be good idea?

I have already found libreswan does not expect such change and would not
build with such version. Do you know about other users of unbound
library, which might be affected? Do you know about any other attempt to
keep ABI but update bugs or features? Has any other distribution solved
such problem?

Cheers,
Petr
