I don't know :)

Yes. Actually, it is probably best to use SASL2_1 only, since sasl 2.1.7 and
2.1.8 ARE compatible, and are NOT to require any recompiling.  The ABI is
SASL 2.1, the minor revision doesn't matter and must NOT be in the symbol.

Once for every ABI change. If you can track down ABI changes to the
function, you can do it the glibc way. Otherwise, bump them all up.

Obviously, symbol versioning is only really useful if you do proper soname
versioning already.
