Motivation:
We need to fail the promise if a failure during handshake happens.
Modification:
Correctly fail the promise.
Result:
Correct websocket client example. Fixes [#6998]
Motivation:
Uptime example is lack of server.
UptimeClient's code style is a little bit different from others, which make reader feel confused.
We don't need to create a new Bootstrap instance each time client reconnect to server.
Modification:
Add UptimeServer and UptimeServerHandler which simply accept all connection and discard all message.
Change UptimeClient's code style.
Share a single Bootstrap instance.
Result:
Uptime server support.
Consistent code style.
Single Bootstrap for all reconnection.

Motivation
OCSP stapling (formally known as TLS Certificate Status Request extension) is alternative approach for checking the revocation status of X.509 Certificates. Servers can preemptively fetch the OCSP response from the CA's responder, cache it for some period of time, and pass it along during (a.k.a. staple) the TLS handshake. The client no longer has to reach out on its own to the CA to check the validity of a cetitficate. Some of the key benefits are:
1) Speed. The client doesn't have to crosscheck the certificate.
2) Efficiency. The Internet is no longer DDoS'ing the CA's OCSP responder servers.
3) Safety. Less operational dependence on the CA. Certificate owners can sustain short CA outages.
4) Privacy. The CA can lo longer track the users of a certificate.

Result
High-level API to enable OCSP stapling
Motivation:
Conscrypt is a Java Security provider that wraps OpenSSL (specifically BoringSSL). It's a possible alternative to Netty-tcnative that we should explore. So this commit is just to enable us to further investigate its use.
Modifications:
Modifying the SslContext creation path to support the Conscrypt provider.
Result:
Netty will support OpenSSL with conscrypt.
Motivation:
Make code easier to read without IDE highlighting.
Modification:
Removed unnecessary 'continue' at end of condition, explicit array creation, unboxing.
Result:
Code easier to read.
Motivation:
Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.
This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.
Modifications:
I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.
Result:
A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.
Motivation:
Since netty shaded JCTools the OSGi manifest no longer is correct. It claims to
have an optional import "org.jctools.queues;resolution:=optional,org.jctools.qu
eues.atomic;resolution:=optional,org.jctools.util;resolution:=optional"
However since it is shaded, this is no longer true.
This was noticed when making JCTools a real bundle and netty resolved it as
optional import.
Modifications:
Modify the generated manifest by no longer analyzing org.jctools for imports.
A manual setting of sun.misc as optional was required.
Result:
Netty OSGi bundle will no longer interfere with a JCTools bundle.
Motivation:
The HTTP Static File Server seems to ignore filenames that doesn't contains only latin characters, but these days people wish to serve files in other languages, or even include some emojis in the filename. Although these files are not displayed on the directory listing, they are accessible by HTTP requests. This fix will make such files more visible.
Modifications:
I've changed the ALLOWED_FILE_NAME pattern to disallow only files that starts with underline, minus or a dot (such as .htaccess), and hide other "unsafe" filenames that may be used to trigger some security issues. Other filenames, including the space character are allowed.
I've also added charset encoding to the directory listing, because the browser default MAY be configured for ISO-8859-1 instead of UTF-8.
Result:
Directory listing will work for files that contains the space character, as well as other Unicode characters.
Motivation:
When Netty HTTP Static File Server does directory listing, it does expose the user.dir environment variable to the user. Although it doesn't a security issue, it is a bad practice to show it, and the user does expect to see the server virtual root instead, which is the absolute path as mentioned in the RFC.
Modifications:
the sendListing method receives a third argument, which is the requested URI, and this is what should be displayed on the page instead of the filesystem path.
Result:
The directory listing pages will show the virtual path as described in the URI and not the real filesystem path.
Removed fallback method
Motivation:
We not need to mark the field as volatile and so this may confuse people.
Modifications:
Remove volatile and add comment to explain why its not needed.
Result:
More correct example.
