This set of changes is the first step to simplify the
writing of handlers, by removing some extraneous
callbacks and making others optional.
init/3 is now init/2, its first argument being removed.
rest_init/2 and rest_terminate/2 have been removed.
websocket_init/3 and websocket_terminate/3 have been removed.
terminate/3 is now optional. It is called regardless of
the type of handler, including rest and websocket.
The return value of init/2 changed. It now returns
{Mod, Req, Opts} with Mod being either one of the four
handler type or a custom module. It can also return extra
timeout and hibernate options.
The signature for sub protocols has changed, they now
receive these extra timeout and hibernate options.
Loop handlers are now implemented in cowboy_long_polling,
and will be renamed throughout the project in a future commit.

REST pastebin example
To try this example, you need GNU make and git in your PATH.
To build the example, run the following command:
$ make
To start the release in the foreground:
$ ./_rel/rest_pastebin_example/bin/rest_pastebin_example console
Then point your browser at http://localhost:8080.
Usage
To upload something to the paste application, you can use curl:
$ <command> | curl -i --data-urlencode paste@- localhost:8080
Or, to upload the file my_file:
curl -i --data-urlencode paste@my_file localhost:8080
The URL of your data will be in the location header. Alternately, you can visit http://localhost:8080 with your favorite web browser and submit your paste via the form.
Code that has been pasted can be highlighted with ?lang= option if
you have highlight
installed (although pygments or any other should work just fine).
This will show the contents of the HTML file:
curl -i --data-urlencode paste@priv/index.html localhost:8080
curl <url from location header>
If your terminal supports color sequences and highlight is installed,
the following command will show the same contents but with HTML syntax
highlighting.
curl <url from location header>?lang=html
If you open the same URL in your web browser and your web browser tells Cowboy that it prefers HTML files, you will see the file highlighted with special HTML markup and CSS. Firefox is known to work.
