Revert "Rename boolean operators for Swift compatibility"

This reverts commit a2d8c1b75902dcd695862ddcf881b05bedd86c2e.
Failing unit test to expose thread-unsafe implementation of -[RACSerialDisposable disposable].
Reimplement RACSerialDisposable with OSSpinLock rather than OSAtomic in order to fix -disposable method to be thread safe.
Formatting.
More code review feedback.
Switch to use CFBridgingRelease.
Bump Specta to wip-0.3
Use an unsafe self reference in -[RACSubscriber init]

A weak reference is unnecessarily expensive, and this disposable is
guaranteed to be used before the captured object disappears.
Reference disposables directly in -didSubscribe…

Avoids any need for weak references, since the RACSubscriber is no
longer being captured.

Fix retain cycle in -didSubscribeWithDisposable:

otherDisposable can't create a cycle with itself, just in case
it's never disposed of.
