* Reorganize examples to be in a separate workspace
This will help to define native tools toolchains for examples
* Remove examples-related part from main WORKSPACE file
* Copy .bazelrc to the examples workspace.
* correction for Bazel HEAD compatibility
* Changes to run nested workspace tests from main workspace
* External C/C++ libraries rules need to pass transitive info
- to have the same interface as cc_library to hide the "implementation details",
so that the information about the install directory and its contents of non-direct external dependencies of external library was available for external build
- this is particularly needed for configure-make rule, where we do not control the way needed libraries are found, so we want to provide the install directory and the -L, -I flags (include and library directories to be searched) consistently,
pointing to the directories under $EXT_BUILD_DEPS
- as a side effect, *.la files that contained links to absolute paths of dependencies (pointing somewhere under ...sandbox/bazel-out/...) now will point to directories under $EXT_BUILD_DEPS and so will be replaced correctly/will not point to paths under the previous sandbox
* External C/C++ libraries rules need to pass transitive info [improve]
By review comments;
- rename to do not collate with internally reserved list, dir, provider
- rename providers to use the same "foreign_cc" prefix and be shorter
- improve providers description
- return back output groups to do not reduce the flexibility

By review comments:
- some more renames
* External C/C++ libraries rules need to pass transitive info: version++
* Correct review comments
