Version v1.49.2

Before this change if -u/--update was in effect we compared the size
of the files to see if the transfer should go ahead.  This was
comparing -1 with an actual size so the transfer always proceeded.

After this change we use the existing `sizeDiffers` function which
does the correct comparison with -1 for files of unknown length.

+// fadvise provides means to automate freeing pages in kernel page cache for
+// a given file descriptor as the file is sequentially processed (read or
+// written).
+//
+// When copying a file to a remote backend all the file content is read by
+// kernel and put to page cache to make future reads faster.
+// This causes memory pressure visible in both memory usage and CPU consumption
+// and can even cause OOM errors in applications consuming large amounts memory.
+//
+// In case of an upload to a remote backend, there is no benefits from caching.
+//
+// fadvise would orchestrate calling POSIX_FADV_DONTNEED
+//
+// POSIX_FADV_DONTNEED attempts to free cached pages associated
+// with the specified region.  This is useful, for example, while
+// streaming large files.  A program may periodically request the
+// kernel to free cached data that has already been used, so that
+// more useful cached pages are not discarded instead.
+//
+// Requests to discard partial pages are ignored.  It is
+// preferable to preserve needed data than discard unneeded data.
+// If the application requires that data be considered for
+// discarding, then offset and len must be page-aligned.
+//
+// The implementation may attempt to write back dirty pages in
+// the specified region, but this is not guaranteed.  Any
+// unwritten dirty pages will not be freed.  If the application
+// wishes to ensure that dirty pages will be released, it should
+// call fsync(2) or fdatasync(2) first.
