Code guarded by the following defines is ancient and has never been
used, so removing.
* RELATIONSHIP_SUPPORTED
* SUPPORTS_IMULTIVALUEPROPERTYCMDLETPROVIDER
* SUPPORTS_CMDLETPROVIDER_FILE
Also removed some unused platform dependent unsafe code.
I (Jason Shirk) ran https://github.com/dotnet/codeformatter with the default rules, basically:
codeformatter /nocopyright "/c:DEBUG,UNIX,CORECLR" @files.rsp
This caused a few problems building, which were fixed up manually.
Notable changes:
`this.` is removed unless needed to disambiguate.
private instance fields are renamed to have a `_` prefix.
private static fields are renamed to have a `s_` prefix.
I left some projects alone (like PackageManagement) and also left some generated code alone.
