xdrgen: Reject specifications that define a name twice

When an RPC specification defines the same type or constant name
more than once, currently xdrgen emits every definition without
complaint. The duplication surfaces later as a C compiler error
about a redefined struct or function that points at generated code
instead of the actual offending line in the .x source.

RFC 4506 Section 6.4 places constant and type identifiers in a
single name space that must be unique within a specification. Add
a semantic check that enforces this rule.
