Using off_t, at least, in DiskAdaptor layer is problematic because
torrent can contain under 2GiB files but total sum of those files may
exceed 2GiB limit, which makes off_t overflow in 32 bit system without
large file support. So we use int64_t in API. We'll check the file
length before download so that it does not exceed max off_t.
Added .cc file for classes/structs that only provided by header
file. Defined non-POD classes' ctor, dtor in .cc file. Moved
implementation code in header file to .cc file for major
classes/strucsts.
Removed SharedHandle::isNull(). Instead we added operator* and
operator unspecified_bool_type. Removed use of WeakHandle and
replaced with raw pointer.
When allocating disk space, for Linux system with fallocate()
system call, first check file system supports fallocate. This
just run fallocate with small chunk and see it succeeds or fails.
If it succeeds, use fallocate() to allocate entire file otherwise
fall back to traditional slower method: writing zeros. This
behavior is enabled in --file-allocation=prealloc, so this is
enabled by default for most modern Linux.
