rustdoc: Allowing specifying attrs for doctests

Browse source 
This adds support in rustdoc to blanket apply crate attributes to all doc tests
for a crate at once. The syntax for doing this is:

    #![doc(test(attr(...)))]

Each meta item in `...` will be applied to each doctest as a crate attribute.
