This ensures that the java bindings are ready before any calls are
made by user code. As a bonus, the JNIEnv* is from the Seq class so I
believe no tricks are required to find the right class loader.
Fixesgolang/go#10903.

Config provides a way to concurrently access Width and Height.
Register provides a way for packages to run code on app state change
without plumbing changes all the way to the process main function.
This is motivated by gl/glutil.Image which needs to rebuild its
textures on start/stop and can be deeply nested.
(See golang.org/cl/9707 for the followup.)
Tested manually on android and darwin/amd64. Doing this kind makes it
clear any CL modifying this code needs a lot of manual testing right
now, so some kind of trybot support is something I'm going to
prioritise.

This is to enable more flexible encoding/decoding of Go string.
For Java, we use UTF16 to be compatible with java string.
For other languages, we will want other way to represent a string.

The State can be used in the Start callback (and lazily-initialized
packages) instead of JavaInit. This stores a reference to the
android.context.Context for the (future) keyboard package and for
setting TMPDIR.
Second attempt at https://golang.org/cl/4400.

When passing a byte array from Java to Go, Seq.writeByteArray JNI
call encodes only the array size and the pointer to the array.
Go-side receives the (size, ptr) pair info during the subsequent
Seq.send JNI call, and copies the elements into a Go byte slice.
We must pin the array elements until Go-side completes copying
so that they are not moved or collected by Java runtime.
This change keeps track of the pinned array info in a 'pinned' linked
list, and unpin them as the Seq memory is freed. The jbyteArray
argument passed to Seq.writeByteArray is needed to release the pinned
byte array elements, but that is a "local reference". It is not
guaranteed that the reference is valid after the method returns. Thus,
we stash its global reference in the 'pinned' list and delete it later
as well.
A similar problem can occur on the byte slice returned from a Go function.
This change does not address the case yet.

This change makes gobind to generate proper Go-side proxy code to
handle interface methods that have parameters and return values.
It allows gobind to accept struct pointer types as parameters
or a return value of a method.
