Make 2.10 macro contexts available under a "blackbox" prefix. See https://issues.scala-lang.org/browse/SI-8209.

Compatibility interface so variances between Scala 2.10 and 2.11 can be accommodated in the same client code. This class is deprecated so that warnings about 2.10 things that are deprecated in 2.11 are hidden. Do not use this class directly, but import from its companion object so that the deprecation warnings will be suppressed.
(Since version 2.11) You should never see this message
