Allow a header to be specified in a CTYPE pragma
You can now say
data {-# CTYPE "some_header.h" "the C type" #-} Foo = ...
I think it's rare that this will actually be needed. If the
header for a CAPI FFI import includes a
void f(ctype x);
prototype then ctype must already be defined.
However, if the header only has
#define f(p) p->j
then the type need not be defined.
But either way, it seems good practice for us to specify the header that
we need.
