`AtomicInt`, `AtomicLong`, `AtomicReference` and `AtomicNativePtr` classes were moved to `kotlin.concurrent` package. The corresponding classes from `kotlin.native.concurrent` were deprecated with warning since Kotlin 1.9.
In order to prepare for further commonization of Atomics API the following changes were made:
* `kotlin.concurrent.AtomicInt`:
* `increment(): Unit` and `decrement(): Unit` methods were deprecated with error
* New methods were added: `incrementAndGet(): Int` , `decrementAndGet(): Int`, `getAndIncrement(): Int`, `getAndDecrement(): Int`, `getAndSet(newValue: Int): Int`
* `kotlin.concurrent.AtomicLong`:
* `increment(): Unit` and `decrement(): Unit` methods were deprecated with error
* New methods were added: `incrementAndGet(): Long`, `decrementAndGet(): Long`, `getAndIncrement(): Long`, `getAndDecrement(): Long`, `getAndSet(newValue: Long): Long`
* Deprecated `AtomicLong()` constructor with default parameter value
* For all atomic classes `compareAndSwap` method was renamed to `compareAndExchange`
See KT-58074 for more details.
