Solly Ross fe8a4dc9d8 Remove last bits of websockify cruft
Issue #449 pointed out that there were some files that were
missed in 6f5148648b.  This
fixes that.

Joel Martin 7c1cd93744 Remove references to wsproxy.
Also, update nova-novncproxy to import websockify instead of wsproxy.

Joel Martin 61265b3a7f Remove files that are now in websockify.
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.

Joel Martin f2538f337d wsproxy, wstelnet: wrap command, WS telnet client.
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.

Joel Martin 71ba9a7a54 wswrapper: update README, DO_MSG def for output.
Update README to mention wswrapper. Add DO_MSG define which controls
whether wswrapper code generates basic output.

Joel Martin fd758dd335 First pass at wsproxy using node (node.js).
Node:
    http://nodejs.org/
    https://github.com/ry/node

It mostly works, but it eventually gets an error from the target which
is probably due to missing support for re-assembly of client
WebSockets frames.
