Move this macro from cli.c to cli.h so apps can use it

without duplicating the macro or the code:

/*!
 * In many cases we need to print singular or plural
 * words depending on a count. This macro helps us e.g.
 *     printf("we have %d object%s", n, ESS(n));
 */
#define ESS(x) ((x) == 1 ? "" : "s")
