----------------------------------
    Attachment: AVRO-1933.patch

Patch set adding more error details to SchemaCompatibility.
Also includes part of AVRO-1931 (though not all tests therein)
Suggest to apply AVRO-1931 first, then this patch.
Contact me if there is any issues.

> Today, the class SchemaCompatibility reports incompatibilities with quite 
> little detail. The whole reader and the whole writer schema is listed, and no 
> particular detail about what was incompatible.
> The attached patch fixes this, introducing a new enum 
> (SchemaIncompatibilityType), and more specific sub-schemas that were 
> incompatible.
> The old, overall picture, is still there - the new compatibility state is 
> encapsulated in the SchemaCompatibilityDetails class.
> Lots of test cases have been added, and there has been refactoring done in 
> the TestSchemaCompatibility and other test classes.
