NAME
       xdr_restrict_buflen - decrease available buffer space

SYNOPSIS
       int xdr_restrict_buflen(struct xdr_stream * xdr, int newbuflen);

ARGUMENTS
       xdr
           pointer to xdr_stream

       newbuflen
           new maximum number of bytes available

DESCRIPTION
       Adjust our idea of how much space is available in the buffer. If we've already used too
       much space in the buffer, returns -1. If the available space is already smaller than
       newbuflen, returns 0 and does nothing. Otherwise, adjusts xdr->buf->buflen to newbuflen
       and ensures xdr->end is set at most offset newbuflen from the start of the buffer.
