Add --max-mmap-limit option
Set the maximum file size to enable mmap (see --enable-mmap
option). The file size is determined by the sum of all files contained
in one download. For example, if a download contains 5 files, then
file size is the total size of those files. If file size is strictly
greater than the size specified in this option, mmap will be disabled.
