Since commit d26a810eb, we've defined bool as being either _Bool from <stdbool.h>, or "unsigned char"; but that commit overlooked the fact that probes.d has "#define bool char". For consistency, make it say "unsigned char" instead. This should be strictly a cosmetic change, but it seems best to be in sync. Formally, in the now-normal case where we're using <stdbool.h>, it'd be better to write "#define bool _Bool". However, then we'd need some build infrastructure to inject that configuration choice into probes.d, and it doesn't seem worth the trouble. We only use <stdbool.h> if sizeof(_Bool) is 1, so having DTrace think that bool parameters are "unsigned char" should be close enough. Back-patch to v12 where d26a810eb came in.
