AVRO-3256: IDL type reference with annotation throws error (#1407)
* AVRO-3256: IDL type reference with annotation throws error
Previous versions would alter the referenced type when encountering an
annotation on (for example) a field type. This change makes references
read-only.
* AVRO-3256: Document new behavior of annotations
Documented that references to named types cannot be annotated. Also
described where annotations for named types should go.
Lastly, the example has been fixed to match this change, and now also
contains various types of documentation.

> Project: Apache Avro
> Issue Type: Bug
> Components: java, spec, tools
> Affects Versions: 1.11.0
> Reporter: Oscar Westra van Holthe - Kind
> Assignee: Oscar Westra van Holthe - Kind
> Priority: Major
> Labels: javacc, pull-request-available
> Fix For: 1.11.1
>
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> The IDL compiler allows annotations on type references, and applies them on
> the referenced type.
> As can be seen in the test output file {{simple.avpr}}, the type {{MD5}} has
> the property {{"foo"="bar"}}.
> But in the input file {{simple.avdl}}:
> * The type definition in lines 39-40 has no such property
> * Line 53 adds the property to the type for the field {{hash}},
> * But it's also silently added to the type for the field {{nullableHash}} in
> line 55
> Solution: do not accept annotations for type references.
