Use MAX from system.h instead. (compute_buffer_size): New function to compute the input and output buffer sizes, which are now set at 8 times st_blksize with a maximum of 32KiB. Previously the typical block sizes used were 1KiB for pipes and 4KiB for files, and now will be 8KiB and 32KiB respectively. (main): Use it. This change can double throughput on modern systems.
