If two auto-configuration classes with the same name are present,
the conditions report message now uses the fully qualified name for
both instead of the short name.

Fixes gh-11710

Closes gh-12546

Fix a range error when checking for unicode hex chars.

Fixes gh-12716

Update `Restarter` to be much more defensive when attempting to clear
caches. We now use `clearCache()` methods whenever possible, and only
fall back to field access when absolutely necessary. In addition field
access now ignore any exceptions.

Switch process redirection off and instead consume streams
and copy to System.out/System.err.

This reverts commit 32782429.

Switch surefire configuration so that forking isn't used. This seems to
prevent the "Corrupted STDOUT by directly writing to native stream"
errors and will hopefully reduce failures on the CI server.

Update `AutoConfigurationSorter` so that all `@AutoConfigureBefore` and
`@AutoConfigureAfter` classes are considered even if they are ultimately
not part of the requested set.

Prior to this commit, given classes ordered with annotations such that
A -> B -> C a call to sort only [A, B] could return the incorrect order.

Fixes gh-12660

This commit updates Spring Boot's DeferredImportSelector implementations
to group imports in a consistent set. This makes sure ordering is
applied consistently.

Closes gh-12366

Due to timeouts while distributing release artifacts,
this commit uses the async mode for distribution.

Before syncing to maven central, we need to check if all the artifacts
have been published to Bintray. This is done by hitting the Bintray API
till we get the version or until a timeout is reached.

Closes gh-12292

Fix the decoding logic in the AsciiBytes `hashCode` and `matches` to
correctly deal with multi-byte encodings.

Fixes gh-12504

Prior to this commit, `WebMvcTags' would always mark as "NOT_FOUND" or
"REDIRECTION" *any* exchange with responses of 404 and 3xx status, even
if those responses are actually returned by Controller handlers.

This commit checks inverts those checks and first considers if the
"BEST_MATCHING_PATTERN_ATTRIBUTE" request attribute is present and uses
it - then falls back to "NOT_FOUND" and "REDIRECTION" to avoid
cardinality explosion.
