SONAME
------
We opted to not bump the soname for the library, simply because soname bumping
is causing a lot of grief and moaning all over the community so we try to keep
that at minimum. Also, our selected design path should be 100% backwards
compatible for the vast majority of all libcurl users.

Enforce SONAME bump
-------------------
If configure doesn't detect your case where a bump is necessary, re-run it
with the --enable-soname-bump command line option!
