Motivation:
Capturing all packets is expensive. Recording to a ring buffer and
then outputting on a triggering event allows this cost to be reduced.
Modifications:
Add a new handler - NIOPCAPRingCaptureHandler.
This derives from the existing NIOWritePCAPHandler and generates PCAP recordings.
A ring buffer contained in this handler stores the captured packets until RecordPreviousPackets
is received as a user message at which point they are flushed to the sink.
Result:
There is a new handler capable of outputting packet captured data only in the build up to
a known event.

Motivation:
The test suite for some reason imported NIO as @testable which is
verboten.
Modifications:
Don't do that.
Result:
Feeling better, compatible with the upcoming NIO 2.10.1.
Motivation:
ServerQuiescingHelper used to swallow close errors and it shoulnd't do
that.
Modifications:
Don't swallow close errors.
Result:
More correctness.
Motivation:
Use B2MDVerifier for the B2MDs in NIOExtras. Already found one bug,
separetely fixed in #51.
Modifications:
Write a basic validation test for all B2MDs.
Result:
Better test coverage.
Motivation:
Especially with TLS but also without, in real production environments it
can be handy to be able to write pcap files from NIO directly.
Modifications:
add a ChannelHandler that can write a PCAP trace from what's going on in
the ChannelPipeline.
Result:
easier debugging in production
Motivation:
to tag versions, we shouldn't depend on `.branch("master")`
Modifications:
depend on swift-nio: 2.0.0-convergence.1
Result:
ready to soon tag the first version
Motivation:
HTTPResponseCompressor is trivially removable, so mark it.
Modifications:
make HTTPResponseCompressor implement RemovableChannelHandler
Result:
HTTPResponseCompressor can be removed
Motivation:
As swift-nio-extras is new, we can require Swift 4.1 which will allow us
to CI less stuff and also won't compatibility stuff for 4.0 that nobody
uses anymore.
Modifications:
require Swift 4.1
Result:
shinier
Motivation:
In a few cases quiescing a server application is useful but it's harder
than necessary with core-NIO. Therefore this adds a helper & a
demonstration.
Modifications:
- add `QuiescingHelper` which helps users to quiesce a channel by
collecting all accepted channels and when needed sends them the
quiescing user event. When all collected channels have closed the
user will be notified and can just shut down the ELG.
- added a demo implementation with a simple HTTP server that quiesces
when receiving a signal
Result:
Make it quite easy to quiesce a server and show users how to do it.
