1. Adds <property name="separateLineBetweenGroups" value="true"/> to CustomImportOrder to enfore blank line between imports groups.

Also add OkHttpReadableBuffer unit test, and increase the test string

Also use array equality assertions in the base test, instead of
comparisons whose return value is discarded.
Fixes#231.
When the description is null, the exception message would be in the form
of "INTERNAL: null", which isn't very attractive, and makes it seem like
an error in itself. If the description is null, just use "INTERNAL".
The checkstyle.xml is a slightly modified version of the upstream Google
checkstyle configuration. All changes have comment describing them.
Lots of warnings were corrected. Examples is the only project that has
warnings still, as the necessary changes require some thought.
-Xlint:-options is not available on some earlier JDK 7s, but won't fail
if unsupported. It prevents the warning wanting bootclasspath specified
since target/source is 1.6.
This allows sooner delivery of errors. We never needed to stop delivery
for unexpected EOS, but instead the application would have been required
to request() another message before delivering. Stalling MessageDeframer
sooner removes the need for the application to request another message
before noticing that the buffers are empty.
The Http2ClientStream should not close the buffer in this case since
it's already been given to the deframer and potentially to the user.
Added cleanup code to MessageDeframer and AbstractClientStream to make
sure that we free the Buffer when appropriate.
Some early grpc users on Android are using a very old Guava. They are
working on upgrading, but it will take time. This alone is not enough
for "old guava" compilibility; expect more to come.
OkHttp no longer cancels all calls on shutdown, as we want to allow
graceful shutdown. Such cancelling behavior will likely be provided by
Channel in the future.
OkHttp should now have a thread-safe implementation of newStream.
Previously 'lock' was not held when checking goAway and the checking in
AbstractClientTransport was redundant.
Netty was thread-safe, but it was very hard to tell what guarantees were
necessary and what guarantees each piece was providing.
Previously streams were being partially orphaned if there was an
interruption during stream creation. To handle cancellation,
AbstractClientStream's cancel() had to be changed remove the
"optimization" otherwise, again, the stream would be orphaned.
This change loses asynchronous notification of channel state-change and
a way to wait until the channel is actually connected. Both of these are
expected to be added back as part of a health API. The important
distinction from Service is that ChannelImpl never permanently fails and
can revert from being started to connecting again.

Summary of changes:
1) Merged the interfaces MessageDeframer2.Sink and DeframerListener into
MessageDeframer2.Listener. This simplifies the interface of
MessageDeframer2 quite a bit.
2) Added a deliveryPaused() handler to MessageDeframer2.Listener, which
is called by the deframer when there is not enough data to read/deliver
the next message.
3) Modified AbstractStream and AbstractClientStream to manage the timing
of when the closed() event is delivered to the listener. The
transportReportStatus ultimately controls this by creating a task to
close the listener. It either runs this task immediately or when the
next deliveryPaused() event occurs.

Headers and trailers are only received on client-side, so we need a
client-specific listener. Close() also has slightly different semantics
between server-side and client-side.

We purposefully avoid going through the (de)framer, since close()
behavior is specific to whether on client or server.
AbstractClientStream and AbstractServerStream handle mapping the events
to appropriate semantics, but require stashing status/trailer for later
use.
It was very interesting getting to a point where we could support the old
and new protocol; that is probably the most detailed-oriented portion of
the CL. There are some interface hacks going on, but those will
naturally be removed when we trash the gRPC v1 framer.

Using MethodDescriptor before was abusive, but the alternative was not
clear.
The new gRPC protocol causes things to become more obvious. Headers,
method name, and timeout were the interesting things on the
MethodDescriptor. In the new protocol, headers are no longer going to be
treated differently from context. We are fine with passing the method
name. So that leaves just timeout, which we really will need more
methods for on the ServerCall object anyway.

More bugs were lurking in this section of code. In some unknown way,
code I'm working on triggered frequent (9/10) failures of
test_TestServiceBenchmarks. These were all possible to be triggered on
HEAD, but for some unknown reason are not.
I am pretty certain we have at least one transport that handles
exceptions poorly, such as by throwing away the exception and not
informing the Operation of the error, which causes this test to time out.
Timeouts in this test are thus likely an indicator of a real bug, even
when it doesn't show any exception, because there was likely an exception
and it was eaten without logging.
Bugs fixed (in order of discovery):
1) In Deframer, currentLength and inFrame were not reset after
consuming a context or status message.
2) In consolidate(), if suffix was greater than the buffer and the
buffer contained data, the data would be lost.
3) In Deframer, some (unknown) Operation's addPayload() did not consume
all of the provided InputStream immediately (maybe it does so on
another thread), leaving those bytes in frame.

SessionCall is updated to implement changes to Call, but it is replaced in the

You can see what glue is necessary to join the Transport and Stub APIs. The

unrelated and necessary because the Channel uses a separate thread to run
Call.Listener. Other parts will be necessary because Channel must intervene
