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.
