Calculate caching state outside of TaskOutputs

Avoid use of `startParameter.searchUpwards` in tests

When `GradleBuild` tasks were used in integration tests, we were often

resorting to `startParameter.searchUpwards = false` to target an isolated

build script. Instead, use an explicitly defined `settings.gradle` in each target

build.

Use global init script to set mirrors for buildSrc (#6627)

Raise minimum build JVM version to Java 8

Use external repository mirrors in build (#6094)

We've been bitten by external repository fluctuation for a long time.

This PR makes most of tests use repository mirrors set up by ourselves

via init script and system property.

There're still some tests not switching to mirrors, which would be fixed

in follow-up commits.

Re-enable Play/Scala tests on Java 9+ (#5593)

Almost all Play/Scala tests were ignored on Java 9/10, which makes it lack coverage. This PR does:

- Update Scala version to Java9-compatible version according to [JDK compatibility](https://docs.scala-lang.org/overviews/jdk-compatibility/overview.html).

- Update default Play version to latest 2.6.15, which supports Java 9/10

- Adjust corresponding samples. Previous default Play version 2.3.10 was too old (release at 2014).

- Ignored the tests which can't work on Java 9+.

- Separate Play test resources with different versions. For example, Play 2.6 uses `build.gradle` and `Play 2.4/2.5` uses `build.gradle.old`.

- Previously `AbstractMultiVersionPlayContinuousBuildIntegrationTest` didn't have `targetPlatform` configuration, which made multi-version tests meaningless

- Fix `play-logback` configuration for `2.5.18`.

Apply repository mirroring to more sample tests

Also introduces a mirror for JBoss repository

Change int tests to use relevant fixture methods to express their expectations about the build log output.

On CI redirect maven central queries to local repo for integration tests

Fix issue with duplicate compiler daemons and add reuse tests

Configure -Xmx for daemons and workers in various tests

Tweaked the API of `BlockingHttpServer` to make it somewhat more convenient to use in tests.

Use separate output directories for all JVM languages

- Introduce an outputDir on SourceDirectorySet

- Default output directory is now `build/classes/<source directory set name>/<source set name>`

- Example: Java compilation goes to build/classes/java/main instead of build/classes/main

- Adapt JDepend, FindBugs, Test and ValidateTaskProperties tasks to handle multiple class directories

- Deprecate setClassesDir/getClassesDir on SourceSetOutput

- Calling setClassesDir restores old behavior (shared output directory)

- Introduce addClassesDir and getClassesDirs on SourceSetOutput

- OSGi plugin needs a single classes directory, so introduce 'osgiClasses' task that syncs all classes to a single directory

Most of the changes to integration tests are find classes in their new location. Helper methods in AbstractIntegrationSpec

can locate class files vs hardcoding a path.

Squashed commit of sg-split-jvm-classes branch for REVIEW-6502

Reworked `BlockingHttpServer`. Converted to Java and changed the implementation to use the JVM's HTTP server types instead of Jetty internals.
