92efa3c916 Add UptimeServer and adjust UptimeClient's code style.
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.

Modifications:

Skip the API check in run-example.sh

Result:

Be able to run the examples in all cases.

e24a5d8839 Map HTTP/2 Streams to Channels
Motivation:

This allows using handlers for Streams in normal Netty-style. Frames are
read/written to the channel as messages, not directly as a
callback/method call. Handlers allow mixing and can ease HTTP/1 and
HTTP/2 interoperability by eventually supporting HTTP/1 handlers in
HTTP/2 and vise versa.

Modifications:

New handler Http2MultiplexCodec that converts from the current HTTP/2
API to a message-based API and child channels for streams.

Result:

The basics are done for server-side: new streams trigger creation of new
channels in much the same appearance to how new connections trigger new
channel creation. The basic frames HEADERS and DATA are handled, but
also GOAWAY and RST_STREAM.

Inbound flow control is implemented, but outbound is not. That will be
done later, along with not completing write promises on the child
channel until the write actually completes on the parent.

There is not yet support for outbound priority/weight, push promises,
and many other features.

There is a generic Object that may be set on stream frames. This also
paves the way for client-side support which needs a way to refer to
yet-to-be-created streams (due to how HEADERS allocates a stream id, and
the allocation order must be the same as transmission order).

781a85520c Add HTTP/2 Netty tiles example
Motivation:

Adding an example that showcases Netty’s HTTP/2 codec and that is
slightly more complex than the existing hello-world example. It is
based on the Gopher tiles example available here:
https://http2.golang.org/gophertiles?latency=0

Modifications:

Moved current http2 example to http2/helloworld.
Added http2 tiles example under http2/tiles.

Result:

A Netty tiles example is available.

d94eab76b6 HTTP/2 examples run script support
Motivation:
The example script has some changes that have not yet been backported.  These changes should be backported.

Modifications:
run-example.sh changes related to http/2 are backported

Result:
HTTP/2 examples can be run on the 4.1 branch.

8ba9e5bede Add logLevel property to enable different log levels for the examples.
Motivation:

When running the examples using the provided run-examples.sh script the
log level is 'info' level. It can be handy to be able to configure a
different level, for example 'debug', while learning and trying out the
the examples.

Modifications:

Added a dependency to logback-classic to the examples pom.xml, and also
added a logback configuration file. The log level can be configured by
setting the 'logLevel' system property, and if that property is not set
the default will be 'info' level.
The run-examples.sh was updated to show an example of using the system
property to set the log level to 'debug'

Result:

It is now possible to turn on debug logging by settnig a system property
on the command line.

9961cae7cf Use a forked exec-maven-plugin instead of maven-antrun-plugin
Motivation:

maven-antrun-plugin does not redirect stdin, and thus it's impossible to
run interactive examples such as securechat-client and telnet-client.
org.codehaus.mojo:exec-maven-plugin redirects stdin, but it buffers
stdout and stderr, and thus an application output is not flushed timely.

Modifications:

Deploy a forked version of exec-maven-plugin which flushes output
buffers in a timely manner.

Result:

Interactive examples work.  Launches faster than maven-antrun-plugin.

223efc5f99 Clean up the examples
Motivation:

The examples have not been updated since long time ago, showing various
issues fixed in this commit.

Modifications:

- Overall simplification to reduce LoC
  - Use system properties to get options instead of parsing args.
  - Minimize option validation
  - Just use System.out/err instead of Logger
  - Do not pass config as parameters - just access it directly
  - Move the main logic to main(String[]) instead of creating a new
    instance meaninglessly
    - Update netty-build-21 to make checkstyle not complain
  - Remove 'throws Exception' clause if possible
- Line wrap at 120 (previously at 80)
- Add an option to enable SSL for most examples
- Use ChannelFuture.sync() instead of await()
- Use System.out for the actual result. Use System.err otherwise.
- Delete examples that are not very useful:
  - applet
  - websocket/html5
  - websocketx/sslserver
  - localecho/multithreaded
- Add run-example.sh which simplifies launching an example from command
  line
- Rewrite FileServer example

Result:

Shorter and simpler examples.  A user can focus more on what it actually
does than miscellaneous stuff.  A user can launch an example very
easily.

37931306d5 Use maven-antrun-plugin instead of exec-maven-plugin
Motivation:

exec-maven-plugin does not flush stdout and stderr, making the console
output from the examples invisible to users

Modification:

Use maven-antrun-plugin instead

Result:

A user sees the output from the examples immediately.

d4f2488eac Bash 3 compatibility
Motivation:

Mac OS X ships Bash 3, and it does not have an associative array
(declare -A).

Modifications:

Do not use an associative array.

Result:

Can run examples on Mac OS X using run-example.sh

4436870b28 Clean up the execution mechanism of examples
Motivation:

- There's no way to pass an argument to an example.
- Assigning a Maven profile for each example is an overkill.
  It makes the pom.xml crowded.

Modifications:

- Remove example profiles from example/pom.xml
- Keep the list of examples in run-example.sh
- run-example.sh passes all options to exec-maven-plugin.
  For example, we can now do this:

    ./run-example.sh -Dssl -Dport=443 http-server

Result:

- It's much easier to add a new example and provide an easy way to
  launch it.
- We can still pass an arbitrary argument to the example being launched.
  (I'll update all examples to make them get their options from system
  properties rather than from args[].

c77375cf54 Clean up example execution
Motivation:

- example/pom.xml has quite a bit of duplication.
- We expect that we depend on npn-boot in more than one module in the
  near future. (e.g. handler, codec-http, and codec-http2)

Modification:

- Deduplicate the profiles in example/pom.xml
- Move the build configuration related with npn-boot to the parent pom.
- Add run-example.sh that helps a user launch an example easily

Result:

- Cleaner build files
- Easier to add a new example
- Easier to launch an example
- Easier to run the tests that relies on npn-boot in the future
