 732 + * The file layout is:
 733 + *    magic[2]
 734 + *    method[1]
 735 + *    flags[1]
 736 + *    timestamp[4]

 738 + *    os[1]
 739 + *    compressed data blocks[N]
 740 + *    crc[4] orig_len[4]
 741 + *
 742 + * resulting in 18 bytes of non compressed data overhead.
 743 + *
 744 + * Files divided into blocks
 745 + * 1 bit (last block flag)
 746 + * 2 bits (block type)
 747 + *
 748 + * 1 block occurs every 32K -1 bytes or when there 50% compression has been achieved.
 749 + * The smallest block type encoding is always used.
 750 + *
 751 + * stored:
 752 + *    32 bits length in bytes.
 753 + *
 754 + * fixed:
 755 + *    magic fixed tree.
 756 + *    symbols.
 757 + *
 758 + * dynamic:
 759 + *    dynamic tree encoding.
 760 + *    symbols.
 761 + *
 762 + *
 763 + * The buffer for decompression in place is the length of the
 764 + * uncompressed data, plus a small amount extra to keep the algorithm safe.
 765 + * The compressed data is placed at the end of the buffer.  The output
 766 + * pointer is placed at the start of the buffer and the input pointer
 767 + * is placed where the compressed data starts.  Problems will occur
 768 + * when the output pointer overruns the input pointer.
 769 + *
 770 + * The output pointer can only overrun the input pointer if the input
 771 + * pointer is moving faster than the output pointer.  A condition only
 772 + * triggered by data whose compressed form is larger than the uncompressed
 773 + * form.
 774 + *
 775 + * The worst case at the block level is a growth of the compressed data
 776 + * of 5 bytes per 32767 bytes.
 777 + *
 778 + * The worst case internal to a compressed block is very hard to figure.
 779 + * The worst case can at least be boundined by having one bit that represents
 780 + * 32764 bytes and then all of the rest of the bytes representing the very
 781 + * very last byte.
 782 + *
 783 + * All of which is enough to compute an amount of extra data that is required
 784 + * to be safe.  To avoid problems at the block level allocating 5 extra bytes
 785 + * per 32767 bytes of data is sufficient.  To avoind problems internal to a block
 786 + * adding an extra 32767 bytes (the worst case uncompressed block size) is
 787 + * sufficient, to ensure that in the worst case the decompressed data for
 788 + * block will stop the byte before the compressed data for a block begins.
 789 + * To avoid problems with the compressed data's meta information an extra 18
 790 + * bytes are needed.  Leading to the formula:
 791 + *
 792 + * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
 793 + *
 794 + * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
 795 + * Adding 32768 instead of 32767 just makes for round numbers.
 796 + * Adding the decompressor_size is necessary as it musht live after all
 797 + * of the data as well.  Last I measured the decompressor is about 14K.
 798 + * 10K of actuall data and 4K of bss.
