Subject: [PATCH] Introduce simple TRUE and FALSE boolean macros.

  Introduce the TRUE and FALSE boolean macros so that everyone can
stop re-inventing them, and remove the one occurrence in the source
tree that clashes with that change.

Signed-off-by: Robert P. J. Day <rpjday@...dspring.com>

---

  once this patch is applied, others can remove all of the superfluous
macro definitions from the source tree at their convenience.

  this was compile tested on x86 with "make allyesconfig".
