Move the hixie disconnect hack to websockets.c. Removed
the remaining websockets vars from rfbClientPtr, so all
websockets stuff is hidden behind an opaque pointer.

Added wspath member to rfbClientRec which holds the
path component of the initial websocket request.

- Add --sslcertfile and --sslkeyfile. These should really be combined
  with the existing x11vnc command line options for SSL support.

For now, only OpenSSL support is activated through configure, since GnuTLS
is only used in LibVNCClient.

[jes: separated this out from the commit adding encryption support, added
autoconf support.]

[jes: moved out GnuTLS and OpenSSL support, added a dummy support, to
separate changes better, and to keep things compiling]

This is not completely standard UTF-8 encoding. Only code points 0-255
are encoded and never encoded to more than two octets. Since '\x00' is
a WebSockets framing character, it's easier for all parties to encode
zero as '\xc4\x80', i.e. 194+128, i.e. UTF-8 256.

This means that a random stream will be slightly more than 50% larger
using this encoding scheme. But it's easy CPU-wise for client and
server to decode/encode. This is especially important for clients
written in languages that have weak bitops, like Javascript (i.e. the
noVNC client).

If the only thing we are waiting on is a WebSockets terminator, then
remove it from the stream early on in rfbProcessClientNormalMessage.

Has a bug: WebSocket client disconnects are not detected.
rfbSendFramebufferUpdate is doing a MSG_PEEK recv to determine if
enough data is available which prevents a disconnect from being
detected.

Otherwise it's working pretty well.

[jes: moved added struct members to the end for binary compatibility with
previous LibVNCServer versions, removed an unused variable]

This bug occured when a second telepathy tubes client was connected after
the first one had disconnected and the channel (thus, the screen too)
had been destroyed.

The functions gnutls_*_set_priority we used were marked deprecated since
latest GnuTLS version 2.12. However the replacement function
gnutls_priority_set_direct is available since 2.2, which is even lower
than our version requirement 2.4 in configure. The patch just replace
the deprecate function to fix the compile warning.

My bad. There we see what the encodings test is good for ;-)

* Fixed segfault on shutdown.
* Updated to test all encodings.
* Fixed to operate with encodings that split up rects into
  smaller rects.

There can not be more than 255 security types and MSLogon is
RFB 3.6 only.

This fixes a segfault when a server is invoked with the
'-help' commandline argument.
