Message:

Use a new syscall, SYS_KIO_READ, for reading from KIO buffer

Originally, the buffer memory was shared between kernel and
uspace, presumably to avoid the overhead of syscalls.
However, this makes synchronization with kernel impossible,
so it is not possible to ensure it works reliably without
random glitches. Also, relative to everything else /app/kio
does with the data, the syscall overhead is positively tiny.
