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
