mariadb-connector-c/private_library.patch

Summary: Build private symbols library

Some of the private symbols have very generic names and are required
by other connectors, like the ODBC connector. Instead of using
static linking, create a private shared library that simply
exports all symbols. With the exception of exported symbols, it is
identical to the regular library.
