Elias Naur 3e830506b0 mobile/bind: stop tracking foreign objects in the Go reference tracker
ToRefNum only handles Go objects, but it can be passed foreign object
proxies as well. Add a check whether the object is a proxy, and if so,
simply return its refnum and don't track it.

Elias Naur 7df33f4a5c mobile/bind: allow bound packages to refer to imported bound packages
Multiple packages are already supported, but only as if each packages
were bound in isolation. This CL lets a bound package refer to other
bound packages in its exported functions, types and fields.

In Java, the JNI class jclass and constructor jmethodID are exported
so other packages can construct proxies of other packages' interfaces.

In ObjC, the class @interface declarations are moved from the package
.m file to its .h file to allow other packages to constructs its
interface proxies.

Add a supporting test package, secondpkg, and add Java and ObjC tests
for the new cross package functionality. Also add simplepkg for
testing corner cases where the generated Go file must not include its
bound package.

While we're here, stop generating Go proxy types for struct types;
only Go interfaces can be implemented in the foreign language.

Elias Naur 976d0710d0 mobile/bind: merge iOS and Android Go test packages
Currently there is a Go test package for each platform, iOS and
Android. This CL merges them into a single, shared  package. Apart
from the reduced code duplication, the merger stops the tests
diverging further. Most importantly, one shared package clarifies
that the intent of gobind is that the same Go package can be
reused across platforms.

This CL only merges the obvious test duplicates. The rest have been
copied from the ObjC package into the Android test under different
names.

While we're here, demote the long string test to the basictypes
bind test; the test never had a runtime part.

Elias Naur ba0a725146 mobile/bind: avoid intermediate []rune copy converting Java string to Go
Converting a Go string to a string suitable use a specialized function,
UTF16Encode, that can encode the string directly to a malloc'ed buffer. That
way, only two copies are made when strings are passed from Go to Java; once
for UTF-8 to UTF-16 encoding and once for the creation of the Java String.

This CL implements the same optimization in the other direction, with a
UTF-16 to UTF-8 decoder implemented in C. Unfortunately, while calling into a
Go decoder also saves the extra copy, the Cgo overhead makes the calls much
slower for short strings.

To alleviate the risk of introducing decoding bugs, I've added the tests from
the encoding/utf16 package to SeqTest.

As a sideeffect, both Java and ObjC now always copy strings, regardless of
the argument mode. The cpy argument can therefore be removed from the string
conversion functions. Furthermore, the modeRetained and modeReturned modes
can be collapsed into just one.

While we're here, delete a leftover function from seq/strings.go that
wasn't removed when the old seq buffers went away.

Elias Naur 6fca37c69e mobile/bind: replace seq serialization with direct calls
The seq serialization machinery is a historic artifact from when Go
mobile code had to run in a separate process. Now that Go code is running
in-process, replace the explicit serialization with direct calls and pass
arguments on the stack.

The benefits are a much smaller bind runtime, much less garbage (and, in
Java, fewer objects with finalizers), less argument copying, and faster
cross-language calls.
The cost is a more complex generator, because some of the work from the
bind runtime is moved to generated code. Generated code now handles
conversion between Go and Java/ObjC types, multiple return values and memory
management of byte slice and string arguments.

To overcome the lack of calling C code between Go packages, all bound
packages now end up in the same (fake) package, "gomobile_bind", instead of
separate packages (go_<pkgname>). To avoid name clashes, the package name is
added as a prefix to generated functions and types.

Also, don't copy byte arrays passed to Go, saving call time and
allowing read([]byte)-style interfaces to foreign callers (#12113).

Finally, add support for nil interfaces and struct pointers to objc.

This is a large CL, but most of the changes stem from changing testdata.

The full benchcmp output on the CL/20095 benchmarks on my Nexus 5 is
reproduced below. Note that the savings for the JavaSlice* benchmarks are
skewed because byte slices are no longer copied before passing them to Go.

Daniel Skinner 39fb9d6163 app: remove incorrect call to AInputQueue_detachLooper
Native activity callback onInputQueueCreated does not attach
a looper to the input queue within android.c. Various examples
of first detaching looper on the web are based around use of
native_app_glue_code which does attach a looper before passing
on to user callback.

Calling detachLooper pre-5.0 results in a crash. I didn't track
down exact source for this but code that likely made it's way
into 5.0 given the time frame can be seen to show a recast of
and iter over size() of a container.

This possibly explains the lack of crashing for 5.0+ instead of
potentially referencing a null pointer pre-5.0.

Elias Naur 45143d8b25 mobile/bind: add Android benchmarks
Since the normal Go benchmark machinery cannot readily be used for
Android apps, a new test, TestJavaSeqBench, is added that builds and
runs the new benchmarkpkg package along with its support Java class
SeqBench. Benchmarkpkg mimics Go benchmarking, in particular it
produces benchcmp compatible output.

Benchmarks prefixed with "BenchmarkJava" are for calls from Java into
Go. Benchmarks prefixed with "BenchmarksGo" are the other way around.
Note that all Go benchmarks run against a Java interface implementation
while the Java benchmarks calls Go functions directly. In other words,
every Go call serializes an implicit Java reference, explaining the
higher call times. The JavaRefgo and JavaRefjava tests attempt to
quantify the overhead equivalent for Java.

The "Direct" suffix are for variants that runs the benchmarks from a
new thread or goroutine. For Go it makes little difference, but there
is a noticable speedup when calling Go from Java when there is already
a JNI call context earlier in the stack.

The benchmarks are for Android only for now, but the benchmarkpkg
has been added to the common golang.org/x/mobile/bind package in
anticipation of future iOS support.

Elias Naur 46f9e01d1e mobile/bind: ensure that Java->Go->Java calls stay on same thread
Java methods from Go are run on a thread pool managed on the Java side,
to avoid the complexities of getting Go threads to play along with the
Android JVM. However, for call stacks that contain a Java->Go->Java
chain, this behaviour confuses Java code sensitive to specific threads
if the Go->Java call is executed on an arbitrary thread from the pool.
For example, most Android UI changes must happen on the single UI
thread.

Replace the thread pool with direct calls to mimic ObjC<->Go and
Java->Go calls. Threads not already attached to the JVM are attached.
Introduce a thread local variable to detach such threads at thread exit.

Elias Naur 89fdf89e93 bind: make Seq.RefTracker.createRef obey the refcnt invariant
An inspection of the RefTracker inc and dec methods suggests
that a particular Java Stub instance is included in the javaObjs
map if and only if its reference count, refcnt, is larger than zero.

A newly created reference created by RefTracker.createRef has zero
refcnt but was also inserted in the javaObjs map, violating the invariant.

Fix that by not inserting new references in javaObjs. Without the fix
a Stub instance that were never passed to Go would leak, along with
any other instances it referenced, transitively.

This fixes a Java reference tracking problem, I have not verified if
the same problem applies to the Go and ObjC sides of the Seq machinery.
