I was debbuging some code tonight and i found a pointer that is not been
freed, so i think there is maybe a memory leak, so it is...

there is the malloc caller reverse order:

( malloc cl->statEncList )
	<- rfbStatLookupEncoding
	<- rfbStatRecordEncodingSent
	<- rfbSendCursorPos
	<- rfbSendFramebufferUpdate
	<- rfbProcessEvents

I didnt look the whole libvncserver api, but i am using
rfbReverseConnection with rfbProcessEvents, and then when the client
connection dies, i am calling a rfbShutdownServer and rfbScreenCleanup,
but the malloc at rfbStatLookupEncoding isnt been freed.

So to free the stats i added a rfbResetStats(cl) after rfbPrintStats(cl)
at rfbClientConnectionGone in rfbserver.c before free the cl pointer. (at
rfbserver.c line 555). And this, obviously, is correcting the memory leak.

For backwards-compatibility reasons, we can only add struct members to the
end. That way, existing callers still can use newer libraries, as the
structs are always allocated by the library (and therefore guaranteed to
have the correct size) and still rely on the same position of the parts
the callers know about.

I got annoyed having to specify -resizable all the time; I never use it in
another mode anymore, since I am on a netbook.

The option -no-resizable was added to be able to switch off that feature.

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.
