Experiment to compile to 2.12 and cross to 2.11, drop 2.10.

[ekrich]

• removed all the straight deprecations
• added access to sun.misc.Unsafe in Util - removed in 2.12
• might be useful if anyone wants to update the library for 2.12
• there are many other macro code deprecations that would take time to remove

Compiles except for benchmark and tests. If the build (project/Util.scala) is changed to 2.11.8 only, everything compiles and the tests run so clearly there are some differences when using 2.12.1 that don't work. I suspect that there is still a reference to scala.concurrent.util.Unsafe.instance. This would work in 2.11 but not 2.12.

Note: I used whitebox macros.

This is the sign of scala.concurrent.util

You have a typo with "picking" instead of "pickling" in the second commit. It compiles afterwards.

Thanks for the tip, compiles now with 3 test failures.

The following 3 tests fail probably due to 2.12 lambda encoding differences.

• [ ] AnonfunBinaryTest
• [ ] AnonfunJsonTest
• [ ] Transient2SparkTest

CI worked for 2.11 (no test failures). CI does not support 2.12 compiling. Failed for 2.10 build (removed support from codebase)
