gmputil: assert length is non-zero

Importing, exporting and byteswapping zero length data should not
happen.

Use macro definition so we know from where the assertion is triggered in
the code for easier diagnosing in the future.

When importing datatype.h from gmputil.h, it seems gcc complains on
missing declarations in json.h.
