This is a large commit, which introduces general API for working with
abstraction of Platform.
- Add new abstraction to 'core' - SimplePlatform - which represents
exactly one platform
- Clients are strongly prohibited to create instances of SimplePlatform
by hand, instead, corresponding *Platforms abstraction should be used
(e.g. JvmPlatforms, JsPlatforms, KonanPlatforms)
- Move TargetPlatform to 'core', it represents now a collection of
SimplePlatforms
- Clients are strongly encouraged to use TargetPlatform
(not SimplePlatform) in API, to enforce checks for multiplatform
- Provide a helper-extensions to work with TargetPlatform
(in particular, for getting a specific component platform)
- Remove MultiTargetPlatform in favour of TargetPlatform
- Notably, this commit leaves another widely used duplicated abstraction,
namely, IdePlatform. For the sake sanity, removal of IdePlatform is
extracted in the separate commit.
When plugins DSL is used, there is no need to
manually generate typesafe accessors for extensions and
conventions (by running `./gradlew kotlinDslAccessorsSnapshot`).
See the previous commit for information on the kotlin-reflect vs
kotlin-reflect-api distinction.
Add kotlin-reflect as an explicit runtime dependency of most of the test
configurations because even though they all depend on tests-common, the
runtime dependency on kotlin-reflect is not exported from tests-common
to other modules because the projectTests dependency is not transitive.
