- add util/cformat.sh, which runs clang-format on all C files with the default .clang-format, and on all header files with a slightly modified version. - use correct bracing after multi-line control statements - stop aligning variable declarations to avoid problems with pointer alignment, but retain aligned declarations in header files so that struct definitions look cleaner. - static function prototypes in C files can skip the line break after the return type, but function prototypes in header files still have the line break. - don't break-before-brace in function definitions. ISC style calls for braces on the same line when function parameters fit on a single line, and a line break if they don't, but clang-format doesn't yet support that distinction. one-line function definitions are about four times more common than multi-line, so let's use the option that deviates less.
