libgfchangelog: cleanups on disconnection

[WIP patch as of now, just needs a little tweak]

A pending TODO in the code caused regressions to fail as
bitrot daemons are spawned during volume start (equivalent
to enabling bitrot by default). The problematic part that
casued such failures is during brick disconnections with
unsafe handling of event data structured in the code.

With this patch, data structures are properly cleaned up
with care taken to cleanup all accessors first. This also
fixes potential memory leaks which was bluntly ignored
before.
