Format LINQ code

Almost entirely automated formatting of LINQ code, via VS refactorings (e.g. renaming fields to follow corefx naming guidelines), StyleCop rules (e.g. using braces in many more places), and CodeFormatter (e.g. inserting blank lines in various places, adding readonly in several places).
