Implement option strings that we can use in #ifdefs (where unavoidable)
as a replacement for the evil #define NFOO. If 'device npx' is in the
static kernel, a synthetic option '#define DEV_NPX 1' will be available
to stick in an opt_xxx.h file. "#if NNPX > 0" can be replaced with
"#ifdef DEV_NPX" and we can get rid of the overloaded meaning of the
device count mechanism.
