1137fb1935 libsyntax/ext: trailing commas in builtin macros 
Most notably this changes 'syntax::ext::base::get_single_str_from_tts'
to accept a trailing comma, and revises the documentation so that this
aspect is not surprising. I made this change under the understanding
that this crate is private rustc implementation detail (I hope this is
correct!). After reviewing all call sites, I believe the revised
semantics are closer to the intended spirit of the function.

a4660dfea2 Point at unused arguments for format string 
Avoid overlapping spans by only pointing at the arguments that are not
being used in the argument string. Enable libsyntax to have diagnostics
with multiple primary spans by accepting `Into<MultiSpan>` instead of
`Span`.

18da3c671b Do not expand a derive invocation when derive is not allowed 
1. Change the return type of `expand_invoc()` and its subroutines to
   `Option<Expansion>` from `Expansion`.
2. Return `None` when expanding a derive invocation if the item cannot
   have derive on it (in `expand_derive_invoc()`).

d14d194f61 Support #[allow] etc logic on a per macro level 
This commit extends the current unused macro linter
to support directives like #[allow(unused_macros)]
or #[deny(unused_macros)] directly next to the macro
definition, or in one of the modules the macro is
inside. Before, we only supported such directives
at a per crate level, due to the crate's NodeId
being passed to session.add_lint.

We also had to implement handling of the macro's
NodeId in the lint visitor.
