Some helpers for en/decoding XDR faster

    val s_read_int4_64_unsafe : string -> int -> int

For 64 bit platforms only: Decodes 4 bytes at this string position as a signed 32 bit int in network byte order

There is no index bounds check!

    val s_write_int4_64_unsafe : string -> int -> int -> unit

For 64 bit platforms only: Encodes 4 bytes at this string position as a signed 32 bit int in network byte order

There is no index bounds check!

    val s_read_string_array_unsafe : string -> int -> int -> int32 -> string array -> int

`let pos' = s_read_string_array s pos len max a`: Decodes the XDR repr of an array of strings without length field. The array must start at `pos` in `s`, and may have up to `len` bytes. The array is passed in `a`, and the elements are set by this routine. Returns in `pos'` the position of the first byte after the array. It is checked whether the array is represented within the allowed `len` bytes. If not, `pos'=-1` will be returned, together with an empty array.

`max` is the maximum length of the string elements. `max` is unsigned. If this is violated, `pos'=-2` will be returned.
