We do this simply by omitting the content-type and let the browser
decide upon the mime-type of the sent file. Only exception is
'index.vnc', where we do set the content-type since some browsers
fail to detect it's html when it's ending in '.vnc'

Also, remove superfluous #defines. We close the connection always.

Pure JavaScript, no Java plugin required anymore! (But a recent browser...)

Also, make it warn more generally when no known encryption lib is
available.

Commented out the surrounding '#ifdef _LIBC' to build md5.o with
leading underscores. This is required to match the prototypes defined
in md5.h.

gnutls_certificate_set_x509_trust_file() returns the number of processed
certs and _not_ GNUTLS_E_SUCCESS (0) on success!

Working with “silent make mode” makes debugging a lot of easier
since warnings wont shadowed by useless compiler noise

Do not consume the peeked data if no close frame was detected.

Add common/sha1.h and common/sha1.c so that we have the SHA routines
even if openssl is not available. From the IETF SHA RFC example code.

Remove the UTF-8 encoding hack. This was really just an experiment.

If the protocol passed in the handshake has "binary" then don't base64
encode for the HyBi protocol. This will allow noVNC to request the
binary data be passed raw and not base64 encoded. Unfortunately, the
client doesn't speak first in VNC protocol (bad original design). If
it did then we could determine whether to base64 encode or not based
on the first HyBi frame from the client and whether the binary bit is
set or not. Oh well.

Misc Cleanup:

- Always free response and buf in handshake routine.

- Remove some unused variables.

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.
