Thanks to Michael Sersen for creating images/Logo.svg.

- Add images directory with original SVG logo, favicon, and some
  derivative PNGs of the logo for different purpose.

- Note that license on images/* is CC BY-SA.

- Add utils/img2js.py to take an image and generate a base64 encoded
  data URI string.

- Add base64 encoded data URI screen logo to display in canvas when
  disconnected.

Using HTML5 doctype means CSS pixels sizes must have "px" suffix which
many of them did not. Fix that.

Call waitpid in loop to catch SIGCHLD signals that happen while
handling the original SIGCHLD signal.

Pulled from websockify.

API change: changed include path variable from VNC_uri_prefix to
URI_INCLUDE since websock.js uses the variable and websock.js is no
longer just for noVNC (i.e. websockify is really the canonical
location for websock.js).

Changes to get web-socket-js to work. Right now it's a hack to get
around: https://github.com/gimite/web-socket-js/issues#issue/41. The
hack is to disable caching of the flash objects by appending
"?" + Math.random() to the end of the flash object path (but only when
using IE).

Opera 11 native WebSockets (if enabled) seems to have bad behavior for
the bufferedAmount so add change from websockify project to allow max
bufferedAmount (before send queue is delay) to be configured.

Also, Opera 11 and 10.60 behave like Mozilla regarding the '-' key so
translate it correctly.

If all send data was flushed from the send queue then return true,
otherwise false. This doesn't mean the data won't be sent, just that
it wasn't sent this time and is queued.

Only delay sending data if bufferedAmount is greater than 1000.

This seems to match the intention of the spec better. bufferedAmount
does not mean that we can't send, it's just an indication that the
network is becoming saturated. But Opera 11 native WebSockets seems to
have a bug that bufferedAmount isn't set back to zero correctly so
we'll be a bit more tolerant.

Issue #8: https://github.com/kanaka/noVNC/issues#issue/8

This prevents the "Uncaught exception: TypeError:
'this.__handleEvents' is not a function" everytime the timer fires.

Yay, one of Javascript's worst behaviors; the way it sets "this".

Issues #27 (safari cursor rendering messed up) and #29 (firefox 3.6.10
segault).

Finally found some better reference on the icon/cursor format which is
added to the docs/links file.

It seems like I was missing the XOR section. So setting the cursor
would cause corruptin in Safari rendering or the segfault for firefox.

Move the Advanced Usage, Integration and Troubleshooting sections to
their own pages in the wiki.

Also, update wsproxy.py referneces to be websockify.

Check keyLocation and translate numpad keys into numbers. keyLocation
is not widely supported yet, but it should start percolating into
browsers eventually:

To go along with addition of performance notes to the website.

Update to a build based on 20f837425d4 from gimite/web-socket-js.

This changes the event handling code and fixes the frequent recursive
call into Flash errors.

Copy in include/websock.js from websockify and use that instead. Still
some cleanup of network code but it's a good start.

https://github.com/kanaka/websockify is now the canonical location of
websockify (formerly wsproxy). A copy of the python version is kept
here for backwards compatibility and ease-of-use. The other versions
and related test scripts are in websockify.

wswrapper:

    Getting the wswrapper.c LD_PRELOAD model working has turned out to
    involve too many dark corners of the glibc/POSIX file descriptor
    space. I realized that 95% of what I want can be accomplished by
    adding a "wrap command" mode to wsproxy.

    The code is still there for now, but consider it experimental at
    best. Minor fix to dup2 and add dup and dup3 logging.

wsproxy Wrap Command:

    In wsproxy wrap command mode, a command line is specified instead
    of a target address and port. wsproxy then uses a much simpler
    LD_PRELOAD library, rebind.so, to move intercept any bind() system
    calls made by the program. If the bind() call is for the wsproxy
    listen port number then the real bind() system call is issued for
    an alternate (free high) port on loopback/localhost.  wsproxy then
    forwards from the listen address/port to the moved port.

    The --wrap-mode argument takes three options that determine the
    behavior of wsproxy when the wrapped command returns an exit code
    (exit or daemonizing): ignore, exit, respawn.

    For example, this runs vncserver on turns port 5901 into
    a WebSockets port (rebind.so must be built first):

        ./utils/wsproxy.py --wrap-mode=ignore 5901 -- vncserver :1

    The vncserver command backgrounds itself so the wrap mode is set
    to "ignore" so that wsproxy keeps running even after it receives
    an exit code from vncserver.

wstelnet:

    To demonstrate the wrap command mode, I added WebSockets telnet
    client.

    For example, this runs telnetd (krb5-telnetd) on turns port 2023
    into a WebSockets port (using "respawn" mode since telnetd exits
    after each connection closes):

        sudo ./utils/wsproxy.py --wrap-mode=respawn 2023 -- telnetd -debug 2023

    Then the utils/wstelnet.html page can be used to connect to the
    telnetd server on port 2023. The telnet client includes VT100.js
    (from http://code.google.com/p/sshconsole) which handles the
    terminal emulation and rendering.

rebind:

    The rebind LD_PRELOAD library is used by wsproxy in wrap command
    mode to intercept bind() system calls and move the port to
    a different port on loopback/localhost. The rebind.so library can
    be built by running make in the utils directory.

    The rebind library can be used separately from wsproxy by setting
    the REBIND_OLD_PORT and REBIND_NEW_PORT environment variables
    prior to executing a command. For example:

        export export REBIND_PORT_OLD="23"
        export export REBIND_PORT_NEW="65023"
        LD_PRELOAD=./rebind.so telnetd -debug 23

    Alternately, the rebind script does the same thing:

        rebind 23 65023 telnetd -debug 23

Other changes/notes:

- wsproxy no longer daemonizes by default. Remove -f/--foreground
  option and add -D/--deamon option.

- When wsproxy is used to wrap a command in "respawn" mode, the
  command will not be respawn more often than 3 times within 10
  seconds.

- Move getKeysym routine out of Canvas object so that it can be called
  directly.

- add dup2 functionality. This requires adding a ref cnt to the
  _WS_connections structure so that we only free the structure once
  all dup'd referenced are closed. Also, refactor malloc and free of
  connection structure into _WS_alloc and _WS_free.
- allow select to accept a NULL timeout value which means sleep
  forever instead of segfaulting.
- fix some compile warnings related to ppoll definition.
- move some WebSockets related html test pages into utils and symlink
  them from tests.

Moved websocket.py code into a class WebSocketServer. WebSockets
server implementations will sub-class and define a handler() method
which is passed the client socket after. Global variable settings have been
changed to be parameters for WebSocketServer when created.

Subclass implementations still have to handle queueing and sending but
the parent class handles everything else (daemonizing, websocket
handshake, encode/decode, etc). It would be better if the parent class
could handle queueing and sending. This adds some buffering and
polling complexity to the parent class but it would be better to do so
at some point. However, the result is still much cleaner as can be
seen in wsecho.py.

Refactored wsproxy.py and wstest.py (formerly ws.py) to use the new
class. Added wsecho.py as a simple echo server.

- rename tests/ws.py to utils/wstest.py and add a symlink from
  tests/wstest.py

- rename tests/ws.html to tests/wstest.html to match utils/wstest.py.

- add utils/wsecho.py

- add tests/wsecho.html which communicates with wsecho.py and simply
  sends periodic messages and shows what is received.

Flip table back to be horizontal. More readable.

Flip the feature table to be tall instead of wide.

Added row about "web server" functionality in wsproxy.py.

- Added ability to respond to normal web requests. This is basically
  integrating web.py functionality into wsproxy. This is only in the
  python version and it is off by default when calling wsproxy. Turn
  it on with --web DIR where DIR is the web root directory.

Next task is to clean up wsproxy.py. It's gotten unwieldy and it
really no longer needs to be parallel to the C version.

Warn early about no SSL cert and add clearer warning when a connection
comes in as SSL but no cert file exists.

For the C version, cleanup closing of the connection socket. Use
shutdown for a cleaner cleanup with the client.
