Function silc_buffer_senlarge SYNOPSIS
        static inline
        SilcBuffer silc_buffer_senlarge(SilcStack stack, SilcBuffer sb,
                                        SilcUInt32 size);
DESCRIPTION
        Enlarges the buffer by the amount of `size' if it doesn't have that
        must space in the data area and in the tail area.  Moves the tail
        area automatically after enlarging so that the current data area
        is at least the size of `size'.  If there is more space than `size'
        in the data area this does not do anything.  If there is enough
        space in the tail area this merely moves the tail area to reveal
        the extra space.  Returns FALSE on error.

        This routine use SilcStack are memory source.  If `stack' is NULL
        reverts back to normal allocating routine.
