Convert mime data length to use unsigned long

What we want to use is size_t, but we don't want the implied POSIX
dependency. However, POSIX does say that size_t is an unsigned integer
that is no longer than a long, so it would appear safe to use an
unsigned long as a replacement. Safer at least than unsigned int.
