1. Add support for customizing JSON diagnostics from Cargo …

   Cargo has of rust-lang#7143 enabled pipelined compilation by default which
   affects how the compiler is invoked, especially with respect to JSON
   messages. This, in some testing, has proven to cause quite a few issues
   with rustbuild's current integration with Cargo. This commit is aimed at
   adding features to Cargo to solve this issue.
   
   This commit adds the ability to customize the stream of JSON messages
   coming from Cargo. The new feature for Cargo is that it now also mirrors
   rustc in how you can configure the JSON stream. Multiple
   `--message-format` arguments are now supported and the value specified
   is a comma-separated list of directives. In addition to the existing
   `human`, `short`, and `json` directives these new directives have been
   added:
   
   * `json-render-diagnostics` - instructs Cargo to render rustc
     diagnostics and only print out JSON messages for artifacts and Cargo
     things.
   
   * `json-diagnostic-short` - indicates that the `rendered` field of rustc
     diagnostics should use the "short" rendering.
   
   * `json-diagnostic-rendered-ansi` - indicates that the `rendered` field of rustc
     diagnostics should embed ansi color codes.
   
   The first option here, `json-render-diagnostics`, will be used by
   rustbuild unconditionally. Additionally `json-diagnostic-short` will be
   conditionally used based on the input to rustbuild itself.
   
   This should be enough for external tools to customize how Cargo is
   invoked and how all kinds of JSON diagnostics get printed, and it's
   thought that we can relatively easily tweak this as necessary to extend
   it and such.
