Reorganize the source tree

- WORKSPACE moves up one level
  - this makes //:pkg.bzl effectively //pkg:pkg.bzl
  - put forwarders in place at top level to not break anyone
- tests moves up one level
- toolchains moves up one level
- examples/**/BUILD do not change to the new rule locations
  - this is explicitly to provide some proof that the forwarders work
  - new examples should use the proper paths to .bzl files
  - near the 1.x release we can clean the current ones up

Fixes: bazelbuild#111
