New description:
rephist.h has some prototypes of functions that are not in rephist.c and
that we don't use anymore, e.g., hs_usage_* . Is there a way to find all
of these unused prototypes in all .h files and remove them?

Comment(by nickm):
So the way I'd do it is to write a script use gnu ctags (you want the gnu
one; it does more stuff) to parse the .h files and the .c files, and then
post-process the output to find identifiers that are in the .h files but
not defined in any .c file.
The incant for "all function prototypes and only function prototypes" is
ctags -n --c-kinds=p -f - ./src/*/*.[ch]
and the incant for "all function definitions" is
ctags -n --c-kinds=f -f - ./src/*/*.[ch]
.....
Oh heck, I've practically written the thing already. Finishing it up as a
script and attaching it. There are some false positives left, but it'll
still be useful, I hope.
