mariadb/mariadb-dubious-exports.patch

Prefix mysql_ to the real names of several symbols that have to be exported
from libmysqlclient because mysql-connector-odbc and/or PHP depend on them.
This limits the intrusion on application namespace.

Also, remove all traces of make_scrambled_password and
make_scrambled_password_323, so that references to these functions draw
compile-time warnings, per a suggestion from Paul Howarth in bug #690346.
It doesn't seem worth trying to get rid of all the internal symbols exposed
by mysql.h, but these two are relatively easy to get rid of.
