blackbox and whitebox macros

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/...
