INT-2455: Support HTTP Outbound 'encode-uri' Flag

The `<http:outbound-channel-adapter>` and `<http:outbound-gateway>` now provide
an `encode-uri` option that controls whether the request uri is encoded
(default `true`).

It can be useful in some scenarios with a non standard URL, e.g. RabbitMQ REST API:
'http://foo.RabbitMQ.com/api/queues/%2f/bar.queue' where we must not
encode the '%'.

INT-3001 Field Order in SyslogToMapTransformer

Use a LinkedHashMap instead of HashMap so iterators
retain the original field order.

Fix compile error in STS/Eclipse.

TestUtils exists in both s-i-test and in src/test... in
s-i-core.

Gradle import caused the file module to use the one in
core that was missing a method.

We should look at a better solution but for now, this
commit syncs the two versions.

Also polished to fix white space violations.

INT-2972 FixedMethodFilter - Return Mutable List

Compatibility with SF 3.2.2

Previously the filter returned a Collections.singletonList() when
a match is found.

Spring 3.2.2 attempts to sort the results of MethodFilter.filter()
which fails because the list is immutable.

Continue to return Collections.emptyList() with no match; this
does not cause the sort to fail.

Several tests in MethodInvokingMessageProcessorTests reproduce this
problem with Spring 3.2.2.

Add a test to confirm the Collections.emptyList() does not cause
any problems.

INT-2956 Fix NIO With Custom Deserializers

The TcpNioConnection uses an internal InputStream.

The standard deserializers only use the read() method.

Custom Deserializers might use read(byte[]); the
internal InputStream did not override these methods, possibly
causing the deserializer to hang awaiting data, when none
was coming.

Override these methods, with the appropriate semantics
from the super class...

- Block until at least one byte arrives.
- Return early if no data is available after at least one byte arrives.
- Return -1 if closed when no data arrived.
- Return the number of bytes actually read.

Polishing - PR Comments remove read(byte[]) because it doesn't do
anything different to the superclass method.

INT-2999 Add BeanResolvers to AMQP OB Endpoints

Expressions (routing key, exchange, correlation data) did
not resolve beans. Need to add the BeanFactory (if present)
to the MessageProcessors.

Add test case.
