lukem fa11ebb133 apparently ansi c only required fread(3) to return 0 if size or nmembs == 0. 
however, susv2 adds the same to fwrite(3), so add the explicit check.
document this for both fread & fwrite. move diagassert for buf!=NULL to after
the (size * nmembs) == 0 check.

this has the helpful side effect of preventing the _DIAGASSERT()ion in
fwrite() being triggered by lots of 3rdparty code that calls fwrite() with
buf=NULL count=0
