macro: add a macro to test whether a value is in a specified list
Introduce IN_SET() macro to nicely check whether a value a is one of a
few listed values.
This makes writing this:
if (a == 1 || a == 7 || a == 8 || a == 9)
nicer, by allowing this:
if (IN_SET(a, 1, 7, 8, 9))
This is particularly useful for state machine enums.
