Motivation:
#fileID introduced in Swift 5.3, so no longer need to use #file anywhere
Modifications:
Changed #file to #filePath or #fileID depending on the situation
Motivation
The rise of Swift concurrency has meant that a number of our APIs need
to be recontextualised as async/await capable. While generally this is a
straightforward task, any time those APIs were tested using
EmbeddedChannel we have a testing issue. Swift Concurrency requires the
use of its own cooperative thread pool, which is completely incapable of
safely interoperating with EmbeddedChannel and EmbeddedEventLoop. This
is becuase those two types "embed" into the current thread and are not
thread-safe, but our concurrency-focused APIs want to enable users to
use them from any Task.
To that end we need to develop new types that serve the needs of
EmbeddedChannel and EmbeddedEventLoop (control over I/O and task
scheduling) while remaining fully thread-safe. This is the first of a
series of patches that adds this functionality, starting with the
AsyncEmbeddedEventLoop.
Modifications
- Define AsyncEmbeddedEventLoop
Result
A required building block for AsyncEmbeddedChannel exists.

Motivation:
EmbeddedChannel is an important testing tool, and we want to use it
without needing to bring along the POSIX layer. They are not tightly
coupled. However, it also doesn't belong naturally in NIOCore, so we
should probably put it in its own place.
Modifications:
- Moved EmbeddedChannel and EmbeddedEventLoop to NIOEmbedded.
- Moved the tests to NIOEmbeddedTests
- Duplicated some test helpers
Result:
Easy to use EmbeddedChannel without the POSIX layer.
