v4l2-ctl: merge strings in the usage message
From: Jean Delvare <khali@linux-fr.org>
Function calls aren't cheap. By merging the strings printed by the
usage() function, we reduce the number of times printf (or actually
puts) is called, from 121 to only 4. This makes usage() about twice
as fast as before, and also shrinks the binary size a bit (4 kB).
Priority: normal
