Errors from cppcheck

[OndÅej BÃlka <neleai at seznam dot cz>]

Hi, I ran a cppcheck to find latent bugs. Its output is quite large,
some are false positives (floats are reported because if's used were not
exhaustive...)

Does somebody go through these issues and fix them? I changed format to
be shell script that opens relevant lines in vim.
