Merge branch 'nick/orber/recursive_types/OTP-8868' into maint-r14
* nick/orber/recursive_types/OTP-8868: Support for recursive unions and structs. Break loop if recursive TypeCode. Added basic tests for recursive uinions and structs. Removed test code. Added partial support for recursive IDL types. Conflicts: lib/ic/doc/src/notes.xml lib/ic/vsn.mk lib/orber/vsn.mk
