Previously, there was a `synchronized` block in the `GroovyScriptExecutingMessageProcessor`
to achieve thread-safety around script variables.
In addition, the parsing and executing logic was delegated to `GroovyScriptFactory`, who, in turn,
has its own `synchronized` around script parsing.
This causes a bottleneck in a messaging architecture.
* Introduce `GroovyScriptExecutor implements ScriptExecutor`
to encapsulate Groovy parsing and executing logic
* synchronize via `ReentrantLock` only when script resource `isModified()`

INT-3166: Fixes and Polishing
INT-3166: add synchronized double check
INT-3166: Remove `GroovyScriptExecutor`
Polishing tests and logic around exceptions
Fix up some white space issues in Groovy*Tests
Previously, there was no logic to check, if a JSR223 script
was modified should be refreshed from the external resource.
* Fix `RefreshableResourceScriptSource` to take care of refreshing
on call `isModified()`
* Add `scriptSource.isModified()` before getting script text
* Introduce `ScriptSourceFactoryBean` to avoid I/O operations, when
there is need to refresh script resource - `refreshDelay < 0`
JIRA: https://jira.springsource.org/browse/INT-3164
INT-3164: change the refresh mutation logic
Remove factory bean - no longer needed.
* Add `<script>` and `<expression>` to `<int:inbound-channel-adapter>`
* Refactoring for `DefaultInboundChannelAdapterParser`
* Introduce `ScriptExecutingMessageSource` to allow scripts' `MessageProcessor`
implementations work as a source for polling endpoint

INT-2867: documentation
In addition the tests for Lifecycle attributes
Polishing
Make 'lang' attribute optional on a script element and
attempt to derive the language from the file extension.
Change return value on ScriptParser.deriveLanguageFromExtension to the language name

INT-3011 Pass BeanClassLoader and BeanFactory to GroovyScriptFactory
INT-3011 Move 'implements BeanFactoryAware, BeanClassLoaderAware'

Copy schemas, cleanup whitespace, update spring.schemas files,
update version in AbstractIntegrationNamespaceHandler.
For each schema compared the 2.2 version with the 3.0 version
(diff -w), ensuring the only difference is the import of
3.0 schemas (where appropriate) instead of 2.2.
Add 2.2 versions of module schemas.
JMX is already covered by an existing pull request.
INT-2536 Schema Check
Bump version for schema check in
AbstractIntegrationNamespaceHandler.
INT-2536 Remove Schema Versions
Some test config files had 2.1 versioned schemas.
