* scala.reflect.macros.BlackboxMacro to scala.reflect.macros.blackbox.Macro
* scala.reflect.macros.WhiteboxContext to scala.reflect.macros.whitebox.Context

When an application of a blackbox macro expands into a tree `x`,
the expansion is wrapped into a type ascription `(x: T)`, where `T` is
the declared return type of the blackbox macro with type arguments and
path dependencies applied in consistency with the particular macro
application being expanded.
This invalidates blackbox macros as an implementation vehicle
of type providers.

This is the first commit in the series. This commit only:
1) Splits Context into BlackboxContext and WhiteboxContext
2) Splits Macro into BlackboxMacro and WhiteboxMacro
3) Introduces the isBundle property in the macro impl binding
Here we just teach the compiler that macros can now be blackbox and whitebox,
without actually imposing any restrictions on blackbox macros. These
restrictions will come in subsequent commits.
For description and documentation of the blackbox/whitebox separation
see the official macro guide at the scaladoc website:
http://docs.scala-lang.org/overviews/macros/blackbox-whitebox.html
Some infrastructure work to make evolving macros easier:
compile partest-extras with quick so they can use latest library/reflect/...

Apparently it is already possible to use macros to customize pattern
matching as described in the comments to the aforementioned JIRA issue.
What's even better - with the incoming addition of c.introduceTopLevel
it becomes possible to generate arbitrarily complex unappliers, even
with heterogeneous types of arguments varying from expansion to expansion
