Added pseudo-tx support for Mail inbound adapters
For polling adapters no changes have been made other then returning a javax.mail.Message instead of its copy so
post-tx dispositions could be performed on it.
For Imap IDLE adapter changes are simiar to the once present in SPCA where TX synchronization logic was added to ImapIdleChannelAdapter
Couple of things to note:
First IDLE receives an array of messages while Polling task receives one message which means i need to sendMessage in the Polling task in the separate thread, so for maintaining single thread semantics we have now it uses single thread executor to send Messages
Renamed MSRH to TransactionalResourceHolder since we no longer use 'source' anywhere and in the case of IDLE there is no MessageSource. Its is truly a holder of attributes we want to make available for use (e.g., SpEL)

Add general capability to advise just the handleRequestMessage
part of an AbstractReplyProducingMessageHandler.
This is to advise just the immediate operation, and not the
entire downstream flow.
Uses include:
* outbound gateway post processing
* adding retry behavior using spring-retry
* adding circuit breaker functionality
Initial commit for review.
Also need to advise simple message handlers (such as file
etc) to allow them to post-process file operations
with payload.delete(), payload.renameTo(...) etc.

Stateless and Stateful retry using spring-retry. Stateless
means the RetryTemplate performs the retries internally.
Stateful means the exception is thrown (e.g. to JMS container)

Don't catch Throwable.
Move Advice classes to handler.advice package.
Remove M3 disposition-* attributes on File/(S)FTP inbound adapters.
Add <pseudo-transactional/> and <transaction-synchronization/> elements
to <poller/>.
These elements provide the following attributes:
* on-success-expression
* on-success-result-channel
* on-failure-expression
* on-failure-result-channel
* send-timeout
<transaction-synchronization/> synchronizes these expression evaluations
with the transaction, such that they are executed immediately after
the commit/rollback.
<psuedo-transactional/> is used for a non-transactional poller.
When an <advice-chain/> is provided to the poller, <psuedo-transactional/>
and <transaction-synchronization/> are synonyms; and the behavior is
dictated by whether or not the <advice-chain/> contains a transaction
advice. It is recommended that <pseudo-transactional/> is used when the
<advice-chain/> does not have a txAdvice, and <transaction-synchronization/>
when it does, but the framework does not enforce this.
The expressions have the original (polled) message as the #root variable.
In addition, a BeanResolver is provided, allowing expressions such as
'@someBean.handleSuccess(payload)'.
MessageSources may also implement PseudoTransactionalMessageSource. This
has a number of methods allowing more flexibility in transactional and
non-transactional environents. For example, for backwards compatibility.
the mail-inbound-channel-adapter deletes its polled message after the
receive() rather than after the polled message is sent (when running in
a non-transactional poller). However, when running in a transactional
poller, the delete is done after the transaction commits (but not when
it rolls back).
In addition, MessageSources that implement this interface can optionally
provide an arbitrary object to the success/failure expressions in a
variable named '#resource'.

Add tests for non-tx PseudoTransactionalMessageSource
* Add *disposition-expression* to the inbound file adapter. This allows for operations such as *payload.delete()*, *payload.renameTo()* after the file is processed.
* The result of executing the expression (if any) is sent to the disposition-result-channel.
Initial commit.
Tested with POP3 and IMAP (James) with Sample app.
Essentially moved all the flagging and deleting code
from receive() to closeContextAfterSuccess().
For non-transactional cases, this new method is
called immediately after receiving the message(s),
essentially working as before.
When run from a <transactional/> poller it is
called using TransactionSynchronization after
the transaction commits.
This behavior can be changed by setting
'symchronized="false"' on the poller, which
removes the synchronization and the update
is called immediately after the receive().

The AbstractChannelAdapterParser creates an implicit DirectChannel
if the adapter has no 'channel' attribute.
The Event, TCP, and UDP channel adapter parsers did not bind
this channel to the adapter and AC initialization failed with
'outputChannel is required'.
Further, the event schema marked the channel as being 'required',
precluding this feature.

This is a significant update to the build system, including the changes
listed below. README.md has been updated with instructions on the most
important day-to-day commands.
- Eliminate buildSrc submodule
In favor of using the new bundlor and docbook-reference plugins. The
net effect is a large reduction in number of lines of build code.
Common docbook resources, stylesheets, etc are stored directly in the
docbook plugin.
This means that --recursive is no longer required when cloning and
there will never be a need to use `git submodule` commands. README
files have been updated to reflect.
Use of the new bundlor plugin also means the removal of template.mf
files from the source tree in favor of an inline approach. See
build.gradle for details. Bundlor 'import templates' are built up
programmatically and kept physically close to gradle dependency
declarations, leading to more convenience when changing these values
and hopefully fewer errors / version inconsistencies over time.
Certain tests depended on the presence of template.mf files, all of
which have recently been removed from the source tree in favor of the
new bundlor plugin which allows for inlining bundlor configuration
within the Gradle build script. These tests now create temp files
using the java.io.File API instead.
- Upgrade to Gradle 1.0-milestone-6
The m6 release is significantly faster when resolving dependencies
and has a number of valuable new features over the earlier m3
version. Review the release notes for Gradle 1.0-milestone-6 online
for full details.
- Switch to repo.springsource.org repository
Previously the project build declared as many repositories as
necessary to resolve all project dependencies.
Now depending on a single 'virtual repository' defined within the
SpringSource Artifactory instance at http://repo.springsource.org.
Currently, the virtual repository in use is 'libs-milestone', which
allows for the resolution of all "milestone-or-better" versions of
all S2 and third-party dependencies.
Should snapshot dependencies become required, this value may be
changed from 'libs-milestone' to 'libs-snapshot'. To build only
against GA releases, change the value to 'libs-release'.
- New build plan(s)
Spring Integration build plans have been updated to use the
Artifactory Bamboo plugin and publish to repo.springsource.org.
Build plans have names like 2.1.x to reflect the version under
development, not necessarily the name of the branch, as this may
change over time and across major releases.
- Improve release process
As mentioned above, Spring Integration will now use the Artifactory
Bamboo plugin to publish releases and also use Artifactory's support
for pushing builds directly into Maven Central via oss.sonatype.org.
Generate poms that contain all necessary fields for onboarding at
Maven central (scm, developers, organization, licenses, etc).
Generate -source and -javadoc poms to comply with Maven Central
onboarding rules (and for general good practice anyway).
Generation of PGP signatures, sha1 and md5 checksums are all handled
automatically by Artifactory. These are also requirements for
automated entry into Maven Central.
- Remove source-level pom generation
Automatic generation of Maven poms suitable for use in building
Spring Integration is no longer supported. Generation and
publication of poms for the purpose of dependency management remains
supported.
Sonar support has to date depended on these poms, but will be
switched over to use the Gradle Sonar plugin shortly.
- Eliminate docs subproject
Move docs/src to the root of the project and eliminate docs as a
formal subproject. This simplifies the build in a number of ways,
including removing the need for distinguishing between 'subprojects'
and 'javaprojects' as well as allowing users to build both 'api' and
'reference' docs without qualifying with a ':docs' prefix.
Also rename the src/info directory to src/dist to better reflect that
these files are packaged with the distribution. For example, the
readme.txt there is really the distribution readme, distinct from the
README.md at the root of the project which is for building from source,
etc.
2 modules still had Spring 3.1 transitive dependencies:
* Spring Integration Redis
* Spring Integration Gemfire
1 module was lacking a Jackson dependency:
* Spring Integration AMQP
