Move all examples into Bazel workspace

Those examples will be used for Bazel integration tests and their
sources should be available directly to the Bazel workspace itself.

-Go rules
---------
-
-The files here demonstrate how to use the rules for Go supplied under
-`//tools/build_rules:go_rules.bzl`.  The rules should be considered
-experimental. They support:
-
-  * libraries
-  * binaries
-  * tests
-
-They currently do not support:
-
-  * coverage
-  * race detector
-  * multiple target configurations
-  * //+build tags
-  * C/C++ interoperation (cgo, swig etc.)
-
-
-Testing
--------
-
-Setup a symlink to the Go installation you wish to use,
-
-    ln -s /usr/lib/golang/ tools/go/go_root
-
-or
-
-    ln -s $(go env GOROOT) tools/go/go_root
-
-To build something, run
-
-    bazel build examples/go/...
-
-To run a test, run
-
-	bazel test --test_arg=--test.v examples/go/lib1:lib1_test
-
-
-Writing BUILD rules
--------------------
-
-In the bazel model of compiling Go, each directory can hold multiple
-packages, rather than just one in the standard "go" tool. Suppose you
-have
-
-    dir/f.go:
-
-    package p
-    func F() {}
-
-then in the BUILD file could say
-
-    go_library(
-      name = "q",
-      srcs = ["f.go"])
-
-and you import it with its Bazel name,
-
-    import "dir/p/q"
-
-this add the declared package name as namespace, i.e., it is
-equivalent to
-
-    import p "dir/p/q"
-
-so you use it as follows
-
-    import "dir/p/q"
-    main() {
-      p.F()
-    }
-
-
-Writing tests
--------------
-
-For tests, you should create a separate target,
-
-    go_test(
-      name = "q_test",
-      srcs = [ "f_test.go" ],
-      deps = [ ":q" ])
-
-if the test code is in the same package as the library under test
-(e.g., because you are testing private parts of the library), you should
-use the `library` attribute,
-
-    go_test(
-      name = "q_test",
-      srcs = [ "f_test.go" ],
-      library = ":q" )
-
-This causes the test and the library under test to be compiled
-together.
-
-
-FAQ
----
-
-# Why does this not follow the external Go conventions?
-
-These rules were inspired on Google's internal Go rules, which work
-like this. For Bazel, these make more sense, because directories in
-Bazel do not correspond to single targets.
-
-
-# Do I have to specify dependencies twice?
-
-Yes, once in the BUILD file, once in the source file. Bazel does not
-examine file contents, so it cannot infer the dependencies.  It is
-possible to generate the BUILD file from the Go sources through a
-separate program, though.
-
-
-Disclaimer
-----------
-
-These rules are not supported by Google's Go team.

-Objective C Examples
-======
-
-The example in this directory show typical use of Objective C libraries,
-binaries and imports. Because they build iOS an application they can only be run
-on Mac OSX.
-
-Build the top-level application with
-`bazel build examples/objc:PrenotCalculator`, which when finished prints the
-path to the generated .ipa. which you can then install to your test device. The
-same build will also print the path to an Xcode project directory which you can
-open to continue working with the application in Xcode.
-
-Running `bazel build examples/objc:PrenotCalculatorInstruments` will build and
-run the application to obtain a screenshot, the path to which it then prints.
