    Do the maximum block size check in pcap_read_block().
    
    Do it before we even *try* to read the block, so that it's done in one
    place rather than having to be done in every routine to handle
    particular block types.
    
    The check was missing in the routine to read sysdig event blocks, so if
    we got a huge sysdig even block we'd try to allocate a huge amount of
    memory.
