Subject: [PATCH 03/13] kdb: Use "bool" in "md" implementation where appropriate
Like much of kdb, the "md" implementation used the "int" type to store
boolean values and used 0 for false and 1 for true. While this worked
(and used to be the only way to do things back in the day), we've had
"bool" for a lot of years now. Move the "md" functions to use "bool".
While touching this, we touch a line next to a comment using a style
that's nonstandard for the kdb codebase. Update it in passing.
