If only --cert is specified then continue to assume both certificate
and key are in the same file (key first).

- pass CFLAGS and LDFLAGS in case one needs to use -m32
- link to libcrypto for _ERR_print_errors_fp
- __THROW is non-standard define it to nothing by default
- use b64_ntop and b64_pton instead of mangled versions, OSX doesn't mangle them in the same way
- access() takes two arguments!

- Split out ClientInitialisation state.

- In version 3.3 and 3.7, when the server has no auth (scheme
  1), then we should skip from Authentication to ClientInitialisation.

- Add wsproxy README.md in utils/ directory.

- Document how to build ssl module for python 2.5 and older in wsproxy
  README.

- Update browsers.md to note revision that have the webkit Canvas
  rendering bug: WebKit build 66396 through 68867 (Chrome/Chromium
  build 57968 through 61278).

If shared mode is false, then the server should disconnect other
connections before the current connection is allowed to proceed.

- Style caching gives a small performance speedup in firefox, but not
  much. Might not be worth complexity, but leave it in for now.

- rQwait checks the receive queue to see if there is enough data to
  satisfy the following request. If not it returns true (which is
  almost always translated into an immediate return false by the
  caller).

- rQwait is called quite a bit and this generally allows 4 lines to
  become 1 line where it is called.

- rQwait allows simplification of cuttext processing. No global
  tracking needed anymore.

Overall, about 60 lines less code.

DES is just used once during authentication and is not performance
sensitive so we save some space by generating and/or removing some
lookup tables. Also, shorten some very frequently used variables.

Shaves off about 100 lines.

 - util.js that contains essential functions
 - webutils.js that contains the GUI utility function.js

this helps to include noVNC in other project, especially Cappuccino Application
i

The decrypt functionality is never used so remove it. Also, we can
assume that we are always DES encrypting 16 characters which allows
several things to be simplified in DES.

Overall this removes about 80 lines of code.

- include/rfb.js: Keep track of the number of rects of each encoding
  type and print them out when we close a connection (if 'info'
  logging level).

- tests/vnc_perf.html: first pass at a noVNC based performance
  benchmark.

- utils/wsproxy.py: Fix the output of the record filename.

Read the render mode selected by canvas and report it in the initial
page loaded status message.

- include/util.js: Add type and desc field to conf_default routine.
  Make comment descriptions of settings into desc parameters that can
  be queried. Also, use set_FOO in conf_default to set or coerce the
  current setting so that we always have the right type for the value.

- include/rfb.js, include/default_config.js: add connectTimeout
  setting to address situations with slow connections that may need
  more than 2 seconds.

Yet another weird VNC server behavior: sending a failure and length
before the reason message. To calculated the length, the reason string
is already available, why not just send everything as one packet. Oh
well.

- include/canvas.js: When 'debug' logging, show browser detection
  values.
- test/canvas.html: Only restore the canvas to it's starting state if
  the logging level is not 'debug'.
- wsproxy.py: Append the session number to the record filename so that
  multiple sessions don't stomp on each other.

Update the browser detection code (from mootools) with a fix that
detects firefox 4.0 correctly.

Only clear canvas if log level is not debug instead of using
'#__debug__' in the URL.

Easier to reference from web site (gh-pages branch).

In Safari, local cursor rendering is corrupt. In firefox 3.6.10, local
cursor rendering causes a segfault. Probable that the .cur format is
not 100% compliant (even though it works in Chrome and firefox 3.5 and
firefox 4.0). So just disable it by default until I can figure out how
to address the problems.

This goes along with commit 7e63919e but for the C proxy.

RFB.sendKey(code, down)

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

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.

Filed this issue for this bug:
http://github.com/gimite/web-socket-js/issues/issue/37

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.
