A built-in protocol, designed by NoMachine, should be used to forward the clipboard from client to server and vice-versa in order to replace the current clipboard support that relies on the X protocol and is subsequently subjected to different implementation on different systems.

The main benefit of this implementation is to gain full control on copy&paste operations in a uniformed way. This will get rid of unexpected behaviors due to how operating systems or distributions manage the clipboard and permit more reliable copy and paste operations.

This implementation will also allow to overcome the limit of 256 KB on copy operations.
