-------------------------------------------------------

Commit 5047220cfe9a6f8a640fb10f0e3de266af51630f in tapestry-5's branch refs/heads/master from
kaosko
[ https://git-wip-us.apache.org/repos/asf?p=tapestry-5.git;h=5047220 ]

TAP5-2553: Support pseudo nested JPA transactions etc.

- add all classes from
https://github.com/kaosko/tapestry-jpa-transactions
- rename packages from net.satago.tapestry5.. to org.apache.tapestry5...
- replace code contents of all advice and worker related classes
(CommitAfterMethodAdvice, CommitAfterWorker, JpaTransactionAdvisorImpl)
with the new implementation
- manually merge relevant code from TransactionUnitsModule to JpaModule
- add new dependencies
- remove remaining net.satago. classes
- I could only make the JpaIntegrationTestWithAnnotationsInServiceImplementation test succeeded
by adding the @PersistenceContext
annotations to the app6.UserDAO interface, why is that?
- reformat code according to Tapestry guidelines

> Plain JPA does not support nested transaction but by keeping track of @CommitAfter stack,
we can support "pseudo nested" transactions. The concept was first demonstrated in https://github.com/satago/tapestry-jpa-transactions.
@kaosko started an effort to merge the codebase to T5 (https://github.com/satago/tapestry-jpa-transactions/pull/5)
but because of fundamental limitations in the original design (no support for multiple persistence
units, pre/post commit hooks were only available for the last transaction), @kaosko refactored
the implementation for more general use (https://github.com/kaosko/tapestry-jpa-transactions).
The original code was under Apache license with support from the original authors to merge
the codebase to T5 and the refactored implementation was solely made by @kaosko. This issue
is about merging the refactored implementation to T5.5 and replacing the existing JPA classes
(mainly class workers, advisors) by the those provided by the new implementation.
