auto merge of #12290 : mrshu/rust/lint-warn-by-default, r=alexcrichton

This first part of my attempts to fix #11432.

In this one I only set NonCamelCaseTypes to warn by default and tried to fix errors that were reported by `make check`.

Please feel free to let me know if I missed something or didn't do it the right way.

Thanks.
