  Rename SecurityPrequisite -> SecurityPrerequisite

Closes gh-2179

Mixing Hibernate and a JTA provider may lead to duplicate JTA
dependencies as the API is published with different coordinates.

The following has been applied:

* We now use `javax.transaction:javax.transaction-api` everywhere.
* The `data-jpa` starter has been updated to replace the JBoss JTA
  dependency with the standard one.
* The `jta-bitronix` starter has been updated to use JTA 1.2 instead of
  JTA 1.1 (unfortunately, JTA 1.1 is published with different
  coordinates).
* The `jta-atomikos` starter has been updated to define a dependency on
  JTA as the current version does not do it at all.
* The HornetQ JMS server is also relying on JTA but that dependency
  should have been optional. It has been excluded for the time being as
  it was using (yet) another set of coordinates.

Update LoggingSystems so that they can reinitialize themselves
before logging begins. This allows reset of the root logger (which
may have been set to OFF in beforeInitialize) and also re-evaluation
of systems properties such as PID which may not have been set when
logging configuration was first loaded.

This commit may possibly reintroduce gh-1091, but it seems like
reloading is our only option.

* pull2181:
  Remove duplicate "should" word from README

Ensure that the system temp directory is passed to the Jetty
WebAppContext. This prevents `jsp` folders from appearing in the current
directory.

Fixes gh-2169

Update DispatcherServletAutoConfiguration to alias a MultipartResolver
that is not named correctly. This allows the DispatcherServlet to pick
up any MultipartResolver bean, regardless of its name.

The `joda-time-jsptags.jar` jar file cannot be skipped.

Previously, no configuration properties were discovered on a class using
lombok instead of regular getters/setters.

This commit adds a support for some of the lombok annotations,
specifically that is @Data, @Getter and @Setter. Provides the same
semantic as what lombok is generating.

Closes gh-2114

* pull2165:
  Fix typo in tests

Ensure that the Maven plugin RunMojo attempts to detect the Spring
Loaded agent before deciding if the JVM should be forked.

Fix numerous copy-paste errors in EmbeddedServerPortFileWriter
where PID concepts are referenced.

Update the file log pattern to write the thread name after the `---`
separator. The allows both file and console logs to be parsed in the
same way.

Fixes gh-2136

Update DefaultLogbackConfiguration to include OptionHelper.substVars
when setting the encoder pattern so that ${PID} is correctly expanded.

Fixes gh-2119

Refactor LoggingApplicationListener and LoggingSystem to restore
Spring Boot 1.1 logging behavior. The LOG_FILE and LOG_PATH system
properties are now set before configuring the logger.

The `logging.path` property is now once again optional and will not be
used when `logging.file` is specified. The documentation has also been
updated to reflect the changes.
