Sergei Golubchik afcd7091a0 MDEV-5529 Sync libmysqlclient.so symbol versioning across distributions
An attempt to introduce libmysqlclient.so symbol versioning that is
compatible both with Debian and Fedora all versions: put all symbols into
libmysqlclient_18 version node (as on Debian), but also put aliases of
old symbols into libmysqlclient_16 version node (as on Fedora).

Also use a linker script to create aliases of exported symbols, not
rpm_support.cc source file.

/*
This version script is heavily inspired by Fedora's and Mageia's version
scripts for MySQL client shared library.
But it was modified to support Debian-compatible versioning too.
In RedHat universe, symbols from old libmysqlclient.so.16
keep their libmysqlclient_16 version. New symbols added in
libmysqlclient.so.18 get the new libmysqlclient_18 version.
In Debian all symbols in libmysqlclient.so.18 have libmysqlclient_18 version,
including symbols that existed in libmysqlclient.so.16
We solve this by putting all symbols into libmysqlclient_18 version node,
but creating aliases for old symbols in the libmysqlclient_16 version node.
