This relase introduces new framework RxAtomic that enables using C11 atomic primities in RxSwift as a replacement for deprecated OSAtomic* functions. Carthage users will probably need to include this framework manually.

• Updates deprecated OSAtomic* primitives to use C11 atomic primitives.
• Adds Event, SingleEvent, MaybeEvent and Recorded conditional conformance to Equatable where their Element is equatable on RXTest for clients that are using Swift >= 4.1.
• Adds string to NSTextView.
• Consolidates per platform frameworks to multi-platform frameworks.
• Xcode 10.1 compatible.
