Major restructuring of how streams work. Neither input nor output
streams are now blocking. This avoids stalling the rest of the client or
server when a peer is slow or unresponsive.
Note that this puts an extra burden on users of streams to make sure
they are allowed to do their work once the underlying transports are
ready (e.g. monitoring fds).
Some systems (like TLS) need to send some final data before closing
a connection. Make sure this is properly handled by cleaning up the
security object before closing the underlying network socket.
Implements support in both client and server for the extended
clipboard format first seen in UltraVNC. Currently only implements
text handling, but that is still an improvement as it extends the
clipboard from ISO 8859-1 to full Unicode.
This provides some basic rate limiting that will make it difficult
for an attacker to brute force passwords. Only relevant when the
blacklist is disabled as otherwise the attacker only gets a very
limited number of attempts.
This adds the basic infrastructure and handshake for the QEMU
Extended Key Events extension. No viewer or server makes use of
the extra functionality yet though.
They are created in SConnection's and CConnection's constructors but never destroyed.
There is no reason for the indirection, so lets make them direct members.
A read-only client should not be allowed to kick out other clients.
It will be forced into shared mode, or refused the connection, depending
on the neverShared parameter.
Allow SSecurity to specify AccessRights for SConnection.
SConnection has AccessRights property that specifies what connected client can
do. Set this property to value given by SSecurity after successful
authentication. This way individual SSecurity subclasses can accept clients but
restrict their access.
Move preferred encoding tracking into a server object
Having it in ConnParams made the linker pull all the encoder objects
into vncviewer, making it larger than necessary and giving it extra
parameters in its help output that weren't relevant.
Gets rid of a loooot of code and complexity.
Colour map clients are still supported through an
automatically generated map, but we lose the ability to
develop a client or server that uses colour maps
internally.
Remove the "video" feature and its associated custom JPEG handling.
Having the client specifiy the video region is conceptually wrong
and a problem like this should be handled by better encoding selection.

Implemented support for TightVNC protocol extensions in the server code. This version has one incompatibility with TightVNC 1.3.x viewers - such viewers would not be able to connect without authentication. This will be fixed in the nearest time.
