The go_seq_to_refnum function handles its argument object as a Java
object if it doesn't implement Seq.Proxy. Java classes implemented in
Go does not implement Seq.Proxy, but when passing "this" references to
Go, instances must be treated as a Go object.
Use go_seq_to_refnum_go everywhere "this" is passed to Go, which fixes
field accessors and simplifies the method call case.

Output every Java class, including the support classes, from gobind
-lang=java. In addition, replace Go package export data parsing with
converting from go/ast to go/types. That way, gobind can tolerate
unknown imports as long as the exported Go API doesn't use them.
In a follow-up CL, the gobind gradle plugin will use gobind for a first
pass to expose the generated Java classes to the android plugin.

Generate Cast functions that take a proxy for a Java class or interface,
and return a new proxy with the same reference. The Cast functions
panic if the underlying Java object is not an instance of the expected
type.

Before this CL, the implicit `this` arguments to methods on Java classes
implemented in Go was only supported on overriding methods, because
their parameter count are known. This CL expands support for the `this`
parameter to every exported method. It only recognizes parameters named
`this` declared with a Java wrapper type.

The Java API wrapper generator use interface{} for Java classes
that no Go code references. Return values of unknown types are thrown
away, since they're effectively useless. Since the return values can
be used for nil checks and since casting of Java instances are
supported in CL 30095, this CL returns the naked *seq.Ref results
values instead.

Before, the Java generator let Java interfaces inherit java.lang.Object
methods. However, interfaces strictly doesn't inherit Object and since
the JNI GetMethodID returns NULL for Object methods on interface classes,
stop making Object a super class to interfaces.

When the Java class parser began culling unused constructors, the
logic for determining whether a given Java class has a no-arg
constructor broke when the no-arg constructor is culled. Add
an explicit field for tracking the no-arg constructor property.

Accept Java API interface types as arguments and return values from
bound Go package functions and methods. Also, allow Go structs
to extend Java classes and implement Java interfaces as well as override
and implement methods.
This is the third and final part of the implementation of the golang/go#16876
