Setting Static Analysis Tools for openrw?

[ghost]

I've seen that many opensource projects are using Coverity and Coverage. Probably for openrw it would also be useful.

Clang's static analyzer could be used (and even tested with Travis.)

335 Introduces code coverage and IWYU. valgrind or clang's static analyser would be useful to have also.

Update, there's already some useful staff and in progress:

• clang-tidy #403
• sanitizers #396

I think we should:

• set generating coverage stats for each build,
• test somehow data test on CI (mocking?),
• clang static analyzer (quite useful, could be set on CI),
• maybe check infer
