Message:

I/O subsystem overhaul:

• add more POSIX-like file and stream functions (with real functionality of stdin, stdout, stderr)
• cleanup console access methods (now generic to any console-like device)
• remove unsafe stream functions
• add special open_node(), fd_node(), fd_phone() (file) and fopen_node(), fnode(), fphone() (stream) functions for HelenOS-specific I/O operations
