[03/10] ddoc-cache commit: updated refs/heads/master to 4ffc6b0

[rn...@apache.org]

Add a simple dialyzer task

This fixes a number of dialyzer warnings as well. Mostly for simple
missing matches. I'm not sure it's worth covering all of these cases
just yet but it wasn't hard for this code.

I've also included the ets_lru module in the dialyzer source to help
ensure that the new match APIs are used correctly. It will skip it
if it's not found on the default path or at ETS_LRU_PATH.
