- Added suppressions for dlopen to make plugin test pass.
- Do not pass empty string to mysqld, since my_getopt is
not capable to handle it.
- Re-enabled trailing UNINSTALL PLUGIN statement of plugin.test.
The memory leak described in the bug report happens in libdl, not
in mysqld. On some valgrind installations this error is suppressed
by default, no idea why it isn't suppressed on pb-valgrind.
<observation>
If library remains open after thread has finished, and is closed by
another thread, we get memory leak. But in case library is opened and
closed by the same thread no leak occurs.

mysql-test/lib/mtr_io.pl:
Do not pass empty string since my_getopt is not capable to handle it.
This is required to make plugin.test work on platforms where
ha_example is not compiled.
mysql-test/r/plugin.result:
Updated test result.
mysql-test/t/plugin.test:
Re-enabled UNINSTALL PLUGIN statement. It is a good idea to cleanup
at the end of the test. Anyway bug22694 was fixed while this test
was disabled.
mysql-test/valgrind.supp:
Added suppressions for dlopen to make plugin test pass.
UDF can be created from any library in any part of the server
LD_LIBRARY_PATH.
Allow to load udfs only from plugin_dir.
On windows, refuse to open udf in case it's path contains a slash.
No good test case for this bug because of imperfect error message
that includes error code and error string when it fails to dlopen a
library.
mysql-test/mysql-test-run.pl:
Since plugins are allowed to be open only from plugin_dir:
- there is no sence to update LD_LIBRARY_PATH
- there is no sence to add plugin_dir arg by default
- set UDF_EXAMPLE_LIB_OPT and EXAMPLE_PLUGIN_OPT to be used by
udf and plugin tests accordingly.
mysql-test/r/plugin.result:
Updated test result (we report addition warning).
sql/sql_udf.cc:
Allow to load udfs only from plugin_dir.
On windows, refuse to open udf in case it's path contains a slash.
mysql-test/t/plugin-master.opt:
New BitKeeper file ``mysql-test/t/plugin-master.opt''
mysql-test/t/udf-master.opt:
New BitKeeper file ``mysql-test/t/udf-master.opt''
