We can't easily solve the problem by not allowing Spring Security to
eagerly instantiate everything, but we can be defensive about data.sql
and make sure it is executed even if the listener isn't yet registered.

This commit adds a 'skip' parameter to the 'repackage' goal that is
false by default. When this parameter is enabled, the repackage goal
does not run at all.

This can be used when repackaging should occur conditionally or
when a particular module in a hierarchy should not use this feature.

Relocate DataSourceAutoConfiguration.CONFIGURATION_PREFIX to
DataSourceProperties.PREFIX.

Switch driver class to the more conventionally named
`org.hsqldb.jdbc.JDBCDriver`.

Update ExtendedPathMatchingResourcePatternResolver to use similar
code as the fix for SPR-12095.

Fixes #1411

Previously, ProjectLibraries only considered a configuration's
direct file dependencies. This meant that a transitive file
dependency that should have been pulled in via a project dependency
was not included in the repackaged jar's lib directory.

ProjectLibraries has been updated to walk down the tree of project
dependencies and create libraries for any file dependencies that
are found.

Fixes gh-1368

Updates to prevent the maven-invoker-plugin from downloading remote
snapshot jars. Possibly caused by the recent changes to the
spring-boot-dependencies POM.

Extract useful logic from StartupInfoLogger to a new ApplicationHome
class.

This reverts commit c28026bb.

Add a repositories section to the spring-boot-dependencies POM but
strip it out during a CI build. This allows snapshot and milestone
BOM imports to be used but doesn't pollute published POMs and doesn't
prevent a fresh checkout from building.
