XDR strings, opaques, and net objects should all use unsigned lengths.
To wit, RFC 4506 says:
4.2. Unsigned Integer
An XDR unsigned integer is a 32-bit datum that encodes a non-negative
integer in the range [0,4294967295].
...
4.11. String
The standard defines a string of n (numbered 0 through n-1) ASCII
bytes to be the number n encoded as an unsigned integer (as described
above), and followed by the n bytes of the string.
After this patch, xdr_decode_string_inplace now matches the other XDR
string and array helpers that take a string length argument. See:
xdr_encode_opaque_fixed, xdr_encode_opaque, xdr_encode_array
