Modified internal function parse_option_name() to return error and handle
that error in function callers in case strdup() fails.

In case of memory error, ensure all allocated resources are freed.
Do not append broken option in trace_plugin_options list.

Changed the description of tep_add_plugin_path() API to reflect the
logic of the function. The suffix of plugin files is not hardcoded
to ".so", it depends on the custom plugin loader callback.
