That's a bit more general little helper function; I guess it could go in
util/ somewhere (something like qemu_string_count_delim ???)

That's a strange line - it suggests you need a better name for both

Why bother with -multi-fd-incoming ? Just insist on people using
-incoming defer - I think we'd like to do away with the other forms
of -incoming, it simplifies stuff a lot that way rather than having two
schemes.
