RFB.sendKey(code, down)

If down is not specified then both a down followed by an up code will
be sent.

Addresses this issue:
http://github.com/kanaka/noVNC/issues#issue/14

Safari starts with '\x80' rather than '\x16' like Chrome and Firefox
and having PROTOCOL_TLSv1 doesn't work with Safari. But just removing
the ssl_version allows things to work with Safari wss:// connections.

Also, if the handshake (after SSL wrapping) is null then terminate the
connection. This probably means the certificate was refused by the
client. Unfortunately Safari (the version I have) doesn't cleanly
shutdown WebSockets connections until the page is reloaded (even if
the object is no longer referenced).

Add a new state 'disconnect' to reflect that we are not truly
'disconnected' until we get an onclose event. Add a disconnect timer
to match.

Handle disconnected cleanup better in updateState(). Anytime we enter
in a disconnect/disconnected state, make sure all running state is
cleaned up (WebSocket, timers, canvas).

Always fork handlers processes. Instead printing traffic when
single-processing, print traffic if verbose flag given.

Right now the close() call only calls __flash.close() if readyState is OPEN.
But it should really call close any time that readyState is not CLOSED or
CLOSING.

The case I ran into is when I want to do the following:
1. make a test connection
2. tell the server to setup for a connection
3. connect again

I call close on the test connection, but since it is ignored when CONNECTING,
it eventually times out with a error. But by that time I have already issued a
new connection, it causes the new connection to fail. close() should cancel
CONNECTING state too.

Filed this bug about this issue:
http://github.com/gimite/web-socket-js/issues#issue/35

To work around the flash "recursive call" problem, WebSocket.as has
the onclose event disabled in the close() call and the javascript half
of the close() call does the onclose() call instead. This is fine, but
it needs to be asynchronous to act more like what happens with
a normal WebSockets object. The current behavior is that the onclose()
method is called inline (synchronously) when the close() is called and
this inconsistency make state handling more difficult.

Add -m, --multiprocess option which forks a handler for each
connection allowing multiple connections to the same target using the
same proxy instance.

Cleaned up the output of the handler process. Each process' output is
prefixed with an ordinal value.

Changed both the C and python versions of the proxy.

I've decided that debug/develop/extra features will just be in the
python version of the proxy. The C version (and other versions) will
just have the core functionality (unless someone wants to support it).

web-socket-js now has all the functionality and fixes needed for noVNC
so remove the include/as3crypto_patched directory and the
include/web-socket-js/flash-src directory (i.e. the sources for
web-socket-js). This cleans up almost 3K from the include/ directory.

Update to web-socket-js build based on upstream (gimite/web-socket-js)
9e766377188.

The rfb variable wasn't available at the point settingsDisabled() was
being called since it was called inline with RFB() initialization. To
solve this we pass the updateState rfb variable so that the canvas can
be queried for setting the cursor_uri value.

Preparation for online demo.

Split general playback code into tests/playback.js.

Use timestamps from recording with proxy to playback in realtime.

Apparently the virtualbox VNC server send the size and then the
security type list in separate frames so we need to wait for the full
list.

When the documement/window is scrolled, the onMouseDisable routine was
not properly calculating the position to test whether to ignore the
event or not.

Change RQ and SQ vars to rQ and sQ since caps at the start implies
a classable entity.

This is logical now since the external update callback can be provided
when the object is created so we don't need a separate init function.

It's less efficient on average that base64 (150% vs 133%). It's
non-standard (0 shifted to 256 before encoding). And I rarely use it.

Turned out not to be useful (pretty much never looked at the info once
I added it). The playback test is much more useful for measuring
performance.

getCLength was not using the index (RQi) into the receive queue.

Generally, most servers send hextile updates as single updates
containing many rects. Some servers send hextile updates as many small
framebuffer updates with a few rects each (such as QEMU). This latter
cases revealed that shifting off the beginning of the receive queue
(which happens after each hextile FBU) performs poorly.

This change switches to using an indexed receive queue (instead of
actually shifting off the array). When the receive queue has grown to
a certain size, then it is compacted all at once.

The code is not as clean, but this change results in more than 2X
speedup under Chrome for the pessimal case and 10-20% in firefox.

- This allows the recorded data to be immediately usable by
  tests/vnc_playback.html

Apparently there are versions of UltraVNC that report version 3.6.
This is not a legal version according to the spec, but we'll just
force version 3.3 if we receive it. Thanks to Larry Rowe for the info.

Turns out when Windows is running in QEMU and a window scroll happens,
there are lots of little hextile rects sent. This is slow in noVNC.

- Some recording/playback improvement.
- Add test harness to drive playback of recordings.
- By pulling off the rect header in one chunk we get a 3X speedup in
  Chrome and a 20% speedup in firefox (specifically for the scroll
  test).
- Also, get rid of some noise from creating timers for handle_message.
  Check to make sure there isn't already a pending timer first.

This is very usefull when you need to open a new window (with a new document) from javascript,
without having to reload the script.js.

- Fallback to md5 module if hashlib not there.
- Import parse_qsl from cgi where it is in both 2.4 and 2.6

- Replace URL parsing using "".partition() with urlparse module.

- When a packet with only '\xff\x00' is received, this means the
  client is doing an orderly shutdown. (WebSockets spec version 76)
