This commit creates our own version of javax.servlet.DispatcherType for
configuration purpose as we can use the other one now the servlet api
is optional.

This commit updates database initializers configuration to enable them
automatically only when an embedded `DataSource` is used. Related
configuration properties have been updated to use a more expressive
`DatabaseInitializerMode` enum rather than `Boolean` flag.

Neo4jDataAutoConfiguration is meant to kick in when Spring Data Neo4J is
on the classpath. Yet, we were only checking for the presence of neo4j
itself and the transaction manager provided by spring-tx.
This commit makes sure to back off if Spring Data Neo4J is not present.
Closes gh-10038
This commit also makes sure to generate unique embedded data source and
disable datasource initialization as this is not required by those
tests.
See gh-9889
This commit adds an additional class check to AopAutoConfiguration as
it is main role is to configure `@EnableAspectJAutoProxy` which won't
work properly if `aspectjweaver` is not present.
Closes gh-9880
Previously, background preinitialization was started in response to
an ApplicationEnvironmentPreparedEvent and would complete at an
undetermined time later. This opened a window where SpringApplication
run could return and background preinitialization could still be
in progress. If, within this window, something attempted to configure
the logging system, an IO failure could occur as logging on the
background preinitialization thread would attempt to use resources
that had been closed.
This commit updates BackgroundPreinitializer so that it waits for
preinitialization to have completed when it receives an application
ready or application failed event. This prevents SpringApplication
run from returning while preinitialization is still in progress,
closing the window described above.
With info level logging enabled it appears that background
preinitialization consistently completes before the application ready
event is published. As a result, waiting should have no adverse effect
on performance in normal circumstances. With logging configured such
that background preinitialization outputs a large volume of log
messages (enabling trace logging for the root logger, for example), it
will be slowed down sufficiently for waiting to be necessary.
Closes gh-5669
Background preinitialization triggers static initialization of a
number of components that are slow to initialize. As the
initialization is static, it's only necessary once per class loader.
Previously, a new background preinitialization thread would be
created and started for each ApplicationEnvironmentPreparedEvent.
This commit updates the preinitializer to only create and start the
thread if preinitialization has not already been started for the
current class loader.
Closes gh-9869
