Bug 3067: Improved error reporting in Binding Data Codec

Error reporting in Binding Data Codec was reworked
to throw three additional subclasses of IllegalArgumentException
for specific case of failure:

MissingSchema and MissingSchemaForClass - exception thrown
when schema context associated with codec does not contain
models for supplied class or DOM argument.

IncorrectNesting is thrown when schema is available an user
constructed data with invalid nesting (bypassed generic
compile-time checks).

The checks to determine type of exception are done only
if error condition is detected, so non-error fast path
should not be affected by advanced checks.

Added test which tests these types of exceptions.
