scan_netstring - parse a netstring

       scan_netstring  attempts  to  parse  the netstring in the input buffer (in,len). If the buffer contains a
       valid netstring, then (*dest,*slen) is set to the start and length of the transported string.

       Note that this string is not zero terminated. No copy is made.  scan_netstring points it inside the input
       buffer.

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

       scan_netstring - parse a netstring

       scan_netstring returns the  number  of  bytes  in  the  netstring  (the  outer  representation,  not  the
       transported  inner  string) if parsing worked, or 0 if the input buffer did not contain a valid (or full)
       netstring.
