BUG#28341 - Security issue still in library loading

Browse Source 
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.
