* Avoid inefficient AString -> c_str() -> AString round trip * Avoid redundant string init expressions * Avoid unnecessary return, continue, etc. * Add .clang-format to help with clang-tidy fix-its * Avoid unnecessary passing by value * Avoid unnecessary local copying * Avoid copying in range-for loops * Avoid over-complicated boolean expressions * Some violations missed by my local clang-tidy * Allow unnecessary continue statements * Add brackets * Another expression missed locally * Move BindingsProcessor call into clang-tidy.sh and add space * Fix pushd not found error * Different grouping of CheckBlockInteractionRate
