LibC: fix fread implementation
...
fread() should read until either size*nitems bytes are read or eof
is reached.

Shell: Clean exit on ^D and use getchar()
...
Use getchar() instead of fread(&ch, 1, sizeof(char), stdin). This
is much cleaner.

Init: use read instead of fread()
...
This allows actually correct behaviour. My fread implementation is
flawed. It should not return on '\n'

Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

cmake is now filled with 'sudo' but with sudo timeout this should be

Only reason for it to be big is if you want super large zero padding
