Move repository declarations out of the parent POM and into setting.xml
(except for the default profile). Also added jboss repository in an
attempt to fix the failing CI release.

Fixed gh-1349

The dependency is currently declared in Spring IO Platform from where
it can be removed once it's using a version of Boot that contains
this change. To make the migration of the dependency management from
the Platform to Boot seamless, the dependency is versioned using a
property with the same name as is currently used by the Platform:
javax-cache.version

Closes #1347

There was a reference to an old (fixed) issue in Spring which led to some simplification
of the AuthenticationManager layering as well.

Update MongoDataAutoConfiguration to use the MongoDbFactory when
creating GridFsTemplate.

Fixes gh-1295

Add `management.add-application-context-header` option to disable
the automatic adding of the `X-Application-Context` HTTP header.

Fixes gh-1308

Minor javadoc edits to hint that @ConfigurationProperties can also be
used with @Bean methods.

Fixes gh-1330

Previously, the data scripts were always run in response to the
publication of a DataSourceInitializedEvent, irrespective of
spring.datasource.initialize. While the event won't be published by
DataSourceInitializer if spring.datasource.initialize is false, it
will be published if spring.jpa.hibernate.hbm2ddl.auto has been set.

This commit updates DataSourceInitializer's handling of
DataSourceInitializedEvent to only run the data scripts if
spring.datasource.initialize is true.

Fixes #1336

The request is being made to '/' and, while the application does have
a mapping for '/', that mapping is not looked for before Spring
Security's filter rejects the request with a 401. This means that the
request is considered to be unmapped and this is reflected in the
metric's name.

See #1331 and #1333

Previously, when one or more custom locations were specified on
@ConfigurationProperties, the configuration loaded from those locations
was used in isolation from the default configuration provided by the
environment. Users have been surprised by this behaviour. For example,
it means that a placeholder used in the custom configuration will not
be resolved against the system properties.

This commit adds a new attribute, merge, to @ConfigurationProperties,
that defaults to true. When merge is true the default property sources
are appended to those that are loaded from the custom locations. When
set to false the custom configuration is used in isolation.

Closes #1301

Fixes gh-1331, Fixes gh-1333

Prior to this commit, the internal BeanWrapper used by the
RelaxedDataBinder was not using any conversion service at all. This
commit makes sure to propagate the one that has been configured
internally.

Also a dummy call to a [foo] key seems to have been left and has
been removed. This allows to support Enum as map key.

Fixes gh-1242

The ErrorPageFilter wasn't setting the response status in the case that
there was an error page mapped to the current request (i.e. for all
autoconfigured apps). N.B. this only affects non-embedded apps.

Fixes gh-1320

Fixes gh-1328

Fixes gh-1321

Previously, the ErrorPageFilter would always flush the response
buffer, irrespective of the request being asynchronous. This could
lead to a response being committed prematurely, preventing, for
example, headers being set by subsequent processing.

This commit updates ErrorPageFilter so that in the success case
(status < 400) the response buffer is only flushed if the request is
not async (determined by calling request.isAsyncStarted()). If an
exception's been thrown or the status is >= 400 the response buffer
is always flushed.

Fixes #1316

Previously, Repackager would repackage a jar file as many times as
it was asked to do so. This lead to problems if a user made a mistake
when using Maven that led to the package phase being driven twice,
for example by running "mvn clean install package".

This commit updates Repackager so that a repackage call becomes a
no-op if the source jar's manifest already contains the
Spring-Boot-Version attribute which is added by repackaging.

Fixes #1251

Update EnvironmentEndpoint and ConfigurationPropertiesReportEndpoint
to allow regex patterns in `keys-to-sanitize`.

Fixes gh-1245

Use Java 7 `registerAsParallelCapable` and `getClassLoadingLock` methods
when possible. This should improve performance when running on JDK 7+
whilst still remaining JDK 6 compatible.

Closes gh-1284

Rework flexible PublicMetrics registration introduced in 2be6b3e4 to
restore compatibility with v1.1 VanillaPublicMetrics. The new
MetricReaderPublicMetrics class now exposes metrics from a MetricReader
and VanillaPublicMetrics is deprecated. The MetricsEndpoint can now
exposes a collection of PublicMetric interface directly.

See gh-1094

Rename the newly introduced @ConditionalOnProperty `match` and
`defaultMatch` attributes to `havingValue` and `matchIfMissing`.

Also added a new `name` attribute as an alternative to `value` to
aid readability.

Closes gh-1000
