Andri Yngvason d418b33dd7 Create dedicated RSA-AES stream
The message format isn't really within the domain of the cipher, so it
doesn't belong to the crypto interface.

Andri Yngvason 0cdbf6a602 stream: Add exec_and_send function
This allows us to execute a function right before a leaves the send queue
and is really only useful for NTP as far as I can tell.

Philipp Zabel e19c9ad600 Implement desktop resizing
Implement minimal support for ExtendedDesktopSize pseudo-encoding

The opaque nvnc_desktop_layout structure contains all information
from the SetDesktopSize client message.
