  1. Allow tracking task ID to support reporting timeout error details 

    When a timeout occurs while waiting for a sequence of tasks to finish execution, it is useful to understand which task was executing when the timeout occurred. Using an `Int` as task ID so the `SynchronizedSequenceExecutionHandle` can track it using the efficient lock-free `AtomicInt`, in order to minimize performance cost when tracking is enabled.

  1. Rename SerialSequenceExecutor (#23) 

    Renames `SerialSequenceExecutor` to `ImmediateSerialSequenceExecutor` to better represent the execution is done immediately on the caller thread, since a `ConcurrentSequenceExecutor` limited to a maximum concurrency level of 1 would also be serial.

  1. Fix AtomicInt usages of deprecated atomic APIs (#26) 

    * Fix AtomicInt usages of deprecated atomic APIs

As of iOS 10.0 and MacOS 10.12 the old `OSMemoryBarrier`, `OSAtomicCompareAndSwap64Barrier`, `OSAtomicIncrement64Barrier`, and `OSAtomicDecrement64Barrier, APIs are deprecated. The warnings suggested new APIs are C++ and are not accessible from Swift.

`OSMemoryBarrier` can be directly replaced with `atomic_thread_fence(memory_order_seq_cst)` which is accessible from Swift.

The rest of the suggested C++ APIs `atomic_fetch_add`, `atomic_fetch_sub`, and `atomic_compare_exchange_strong` are not accessible from Swift. This change creates a Objective-C wrapper for these C++ APIs, so Swift code can access them.

* Update TravisCI to use Xcode 10.1

  1. Allow task execution to throw errors (#28) 

    * Allow task execution to throw errors

Adds support to allow task execution to throw errors. The error is then reported back via the `SequenceExecutionHandle.await` method when results are being retrieved.

* Ignore SPM generated scheme

  1. Add AutoReleasingSemaphore (#30) 

    Similar to `DispatchSemaphore`, `AutoReleasingSemaphore` is a synchronization mechanism that ensures only a set number of threads can concurrently access a protected resource. Unlike `DispatchSemaphore`, `AutoReleasingSemaphore` auto-releases all blocked threads when the semaphore itself is deallocated.

  2. Signal concurrency limiting semaphore when task errors (#31) 

    This fixes the issue where if a task throws an error during execution, the concurrency limiting semaphore is never signaled. This can hault the entire sequence since no new tasks can continue execution.
