top: don't wait before final bailout (try top -b -n1).
top: make code a bit more readable.

mount: allow (and ignore) -i

smart_ulltoa5: emit small letters k,m,g... - makes top
more readable

top: use poll instead of select for waiting on one descriptor
smart_ulltoa5: make it more cryptic. -50 bytes.
