* Improve documentation for NIOExtras
Motivation:
Docs will help users do things correctly.
Modifications:
Add missing comments, improve links.
Result:
Better docc documentation
* Docc in NIOHTTPCompression
* NIOSOCKS docc

Motivation:
With NIO 2.32.0 we broke the core NIO module up into modules that split
apart the POSIX layer and the core abstractions. As a result, this
package no longer needs to express a hard dependency on the POSIX layer.
Modifications:
- Rewrote imports of NIO to NIOCore.
- Added NIOEmbedded and NIOPosix imports where necessary in tests.
- Extended soundness script to detect NIO imports.
- Note that the main modules still depend on NIO, which is necessary
for backwards-compatibility reasons. This dependency is unused.
Result:
No need to use NIOPosix.
Motivation:
ServerQuiescingHelper used to swallow close errors and it shoulnd't do
that.
Modifications:
Don't swallow close errors.
Result:
More correctness.
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.
