    libafs: Tidy up iovec allocation and trimming
    
    Tidy up the way that we perform iovec allocation and trimming by
    making the rest of the world look a little bit more like Darwin.
    
    This relies upon a struct uio, followed by 16 iovecs, being able
    to fit into a SmallSpace sized block. On the majority of 32 bit
    systems, such a block is 256 bytes long (on AIX and HPUX it is
    152 bytes). With a 32bit size_t, an iovec is 8 bytes, so 16 of
    them is 128 bytes, and a struct uio is 24 bytes, giving a grand
    total of 152.
