merge 2.11.x onto 2.12.x, Oct 16 2015

there were merge conflicts in the Eclipse config that I resolved with
--ours.  I invite @performantdata to submit a followup PR bringing the
Eclipse stuff into a good state on 2.12.x.

there was a test failure in
test/junit/scala/collection/mutable/OpenHashMapTest.scala
due to the 2.12 compiler emitting the field backing a
private var differently (with an unmangled name).  Lukas
says the difference is expected, so I just updated the
code in the test.

there were no other merge conflicts.

 Consequently, type-parameters in traits may not be view- or context-bounded.
