fmt_netstring - convert a memory buffer into a netstring

       fmt_netstring creates a netstring from a raw memory buffer and returns the length.

       fmt_netstring does not append \0.

       If dest equals FMT_LEN (i.e. is zero), fmt_netstring returns the number of bytes it would have written.

       The raw memory buffer "foo" would become the netstring "3:foo,"

       fmt_netstring  returns  the number of bytes written (or that would have been written, had the destination
       pointer not pointed to NULL).

       If the input buffer is implausibly large, fmt_netstring returns 0 instead.
