Client programs throw warnings about memory loss when executed with --help or alike

[Elena Stepanova]

When a client problem is executed with --version, or --help, or without parameters, it throws warnings about lost bytes, e.g.

Warning: 484 bytes lost, allocated at mysys/my_alloc.c:217, mysys/default.c:1203, mysys/default.c:524, mysys/default.c:468, client/mysqladmin.cc:310, ??:0
Warning: 1024 bytes lost, allocated at mysys/array.c:65, mysys/hash.c:92, mysys/thr_mutex.c:186, mysys/thr_mutex.c:323, sql-common/client_plugin.c:262, libmysql/libmysql.c:134, sql-common/client.c:1708, client/mysqladmin.cc:310
Warning: 1024 bytes lost, allocated at mysys/array.c:65, mysys/hash.c:92, mysys/thr_mutex.c:181, mysys/thr_mutex.c:323, sql-common/client_plugin.c:262, libmysql/libmysql.c:134, sql-common/client.c:1708, client/mysqladmin.cc:310

etc.

From the standard set of binaries produced with DCMAKE_BUILD_TYPE=Debug without any other parameters, observed on
- mysqladmin
- mysqlcheck
- mysqldump (it's message also looks strange: (Warning: 15 bytes lost, allocated at addr2line: 'mysqldump': No such file")
- mysqlimport
- mysql_plugin
- mysqlshow
- mysqlslap
- mysql_upgrade

Not reproducible on maria/5.3, mysql-server/5.5, mysql-server/trunk.

To reproduce,

- build the client program using cmake .. -DCMAKE_BUILD_TYPE=Debug && make;
- start the client program, e.g. client/mysqladmin --help
- see output.
