Mikhail Goncharov 7faaec98e7 Attach diffs produced by git-clang-format as lint messages.
E.g.: https://reviews.llvm.org/D71197?id=233029
Will add a link to file and code to apply the patch in the next PR.

+ don't create TARGET_DIR in scripts;
+ updated section about local build;
+ partially specified inputs / outputs of scripts so it's more transparent what are the results;
+ added symlink to compile_command.json (clang-tidy will need it);
+ add IDEA files to .gitignore.
