Prior to this commit, the `StaticResourceLocation` for favicons would
point to `"/**/favicon.ico"`. This location does not reflect the current
web development landscape, since the png format and size variants are
not supported here. Also, the `"**"` pattern can be costly at runtime
and is deprecated by the new path pattern support in Spring Framework
(see gh-22833).

This commit changes the default locations to `"/favicon.*","/*/icon-*"`,
supporting common use cases such as `"/favicon.ico"`, `"/favicon.png"`
and `"/icons/icon-48x48.png"`.

Update the `AbstractJarWriter` so that it can directly build the layer
index as entries are written. Prior to this commit, a layer tracking
was handled by a decorator class which was broken because it didn't
override enough methods. Since `AbstractJarWriter` has quite a complex
API, it seems sensible to have it handle the layer index directly,
removing the need for a decorator entirely.

Deprecate and provide alternatives for logging properties that are
specific to Logback.

The following Spring Boot properties have been changed:

  * logging.pattern.rolling-file-name ->
    logging.logback.rollingpolicy.file-name-pattern

  * logging.file.clean-history-on-start ->
    logging.logback.rollingpolicy.clean-history-on-start

  * logging.file.max-size ->
    logging.logback.rollingpolicy.max-file-size

  * logging.file.total-size-cap ->
    logging.logback.rollingpolicy.total-size-cap

  * logging.file.max-history ->
    logging.logback.rollingpolicy.max-history

As have the system environment properties that they map to:

  * ROLLING_FILE_NAME_PATTERN ->
    LOGBACK_ROLLINGPOLICY_FILE_NAME_PATTERN

  * LOG_FILE_CLEAN_HISTORY_ON_START ->
    LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START

  * LOG_FILE_MAX_SIZE ->
    LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE

  * LOG_FILE_TOTAL_SIZE_CAP ->
    LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP

  * LOG_FILE_MAX_HISTORY ->
    LOGBACK_ROLLINGPOLICY_MAX_HISTORY

This commit also cleans up and simplifies `DefaultLogbackConfiguration`.

Prior to this commit, the how-to documentation would say that Spring
Boot does not support the h2c protocol. While it's not supported
out-of-the-box with a configuration property, this protocol can still be
configured using server customizers.

This commit documents, with code snippets, the server customizers one
should use to configure the h2c protocol in an application - for each
supported server.

Closes gh-21997

Prior to this commit, tests using the `@WebMvcTest` annotation would not
include the `HttpEncodingAutoConfiguration`. This means that, even if
configured, the encoding filter would not be configured in MVC tests,
resulting in an inconsistency with `@SpringBootTest` tests.

This commit ensures that the `HttpEncodingAutoConfiguration` is included
when `@WebMvcTest` is used.

Previously, when building a layered jar with Maven, dependencies
on modules in the same build were treated the same as any other
dependency, being included in the dependencies or snapshot dependencies
layer based on their version.

This commit updates the default layering when using Maven to include
dependencies on modules in the same build in the application layer by
default. The XML schema has also been updated to allow the layer to be
customized using new <includeModuleDependencies/> and
<excludeModuleDependencies/> elements rather than relying on including
and excluding them via a group:artifact:version pattern.

Closes gh-23463

This commit modifies the logic for finding properties files using
wildcard paths to ignore files if any part of the file path contains
a hidden directory. Hidden directories are common when Kubernetes
mounts config maps onto volumes in a pod, which was causing the same
properties files to be loaded multiple times.
