[cfe-dev] [clang-tidy] Excluding individual files/lines from clang-tidy checks

[Nikita via cfe-dev]

By the way, with line ranges omitted it is easier to ditch JSON and go
for a simpler format.
Like this: 'header1.h:cert-*,boost-*;header2.h:clang-analyzer-*'.
Less cumbersome, more comfortable to work with in, say, CMake files.
