Remove all loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]
This introduces a “pending NODELETE” state in the link map, which is flipped to the persistent NODELETE state late in dlopen, via activate_nodelete. During initial relocation, symbol binding records pending NODELETE state only. dlclose ignores pending NODELETE state. Taken together, this results that a partially completed dlopen is rolled back completely because new NODELETE mappings are unloaded. Tested on x86_64-linux-gnu and i386-linux-gnu.
