Subject: module loader dead code removal and cleanups v2

Hi all,

this series removes support for long term unused export types and
cleans up various loose ends in the module loader.

Changes since v1:
 - move struct symsearch to module.c
 - rework drm to not call find_module at all
 - llow RCU-sched locking for find_module
 - keep find_module as a public API instead of module_loaded
 - update a few comments and commit logs
