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/...

With the advent of quasiquotes, we allowed both arguments and return types
of macro impls to be c.Tree's (as opposed to traditional c.Expr[T]'s).
This warrants an update of macro def <-> macro impl signature mismatch
errors that include a printout of suggested macro impl signatures. Now
along with a signature that contains exprs, we suggest another signature
that has all exprs replaced by trees

Upgrades the way that macro defs are compiled by factoring out most of
the logic in typedMacroBody and related errors in ContextErrors into an
standalone cake. This leads to tighter cohesion and better code reuse
as the cake is isolated from the rest of the compiler and is much easier
to evolve than just a method body.
Increased convenience of coding macro compilation allowed me to further
clarify the implementation of the macro engine (e.g. take a look at
Validators.scala) and to easily implement additional features, namely:
1) Parameters and return type of macro implementations can now be plain
c.Tree's instead of previously mandatory c.Expr's. This makes macros more
lightweight as there are a lot of situations when one doesn't need to
splice macro params (the only motivation to use exprs over trees). Also
as we're on the verge of having quasiquotes in trunk, there soon will be
no reason to use exprs at all, since quasiquotes can splice everything.
2) Macro implementations can now be defined in bundles, standalone cakes
built around a macro context: http://docs.scala-lang.org/overviews/macros/bundles.html.
This further reduces boilerplate by simplifying implementations complex
macros due to the fact that macro programmers no longer need to play
path-dependent games to use helpers.

This brings all the files into line with the .gitattributes
settings, which should henceforth be automatically maintained
by git.

Removes the stubs left out to appease the old starr, fixes macro tests.
