+ don't assume that clang-format has passed if there is no file.
If linters didn't run at all file will be missing.
+ add "gray" icon for the result if it's unknown.
+ assume whole build is failed if clang-format or clang-tidy found something.
+ combine multiple lint messages per line.
Now report is constructed by adding more data from several stages and
represents internal structure rather what API expects.
+ Made all function that don't interact with phabricator free standing
+ Now links list all files in results directory
+ Status icons
Example comment: https://reviews.llvm.org/D71197#1779176 (links don't work).
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.
