What if you want to support something like --server-arg=optname=optval?
(I see that mysql.cc does in fact use mysql_library_init(), or rather
mysql_server_init(), contrary to my earlier assertion about our clients
not using it. But it does the MY_INIT(), load_defaults(), mysql_server_init()
sequence, presumably so that --server-arg can be specified on the command
line or in [mysql] option groups?)
