[PATCH 10/12] server: Introduce get_next_console_request request.

I considered using ioctl for this instead of server request (in fact, my 
first implementation used that), but it required rather unpleasant 
messing with ioctl buffers to pass additional informations for 
server<->conhost connection.

This will need to be extended for:
- blocking read calls
I will queue them on server side and pass only one at the time to conhost.
- screen buffer calls
We may have multiple screen buffers for each console, so we will need to 
pass screen buffer ids to conhost and add additional calls for tracking 
them.
