Added 'falloc' parameter for --file-allocation option. 'falloc'
allocation mode uses posix_fallocate() system call to allocate
file on disk. If you are using newer file systems such as ext4
(with extents support), btrfs or xfs, 'falloc' is your best
choice. It allocates large(few GiB) files almost instantly.
Don't use 'falloc' with legacy file systems such as ext3 because
it takes almost same time as 'prealloc' and it blocks aria2
entirely until allocation finishes. 'falloc' may not be
available if your system doesn't have posix_fallocate() system
call.
