This gives you more control over how long rclone will run for, making
it easier to script backups, e.g. via cron. Once the `--max-duration`
time limit is reached, no new transfers will be initiated, but those
already in-flight will be allowed to complete.
Fixes#985
Before this change the expect/continue timeout was set to
--conntimeout which was 60s by default which is too long to wait.
This was noticed when using s3 with a proxy which apparently didn't
support expect / continue properly.
Set --expect-continue-timeout 0 to disable expect/continue.
Before this change --update would transfer any file which was newer
than the destination regardless of whether it had changed or not.
This is needlessly wasteful of bandwidth.
After this change --update will only transfer files if they are newer
**and** they are different (checked with checksum and size).
It's likely a mistake to use `--use-server-modtime` if you're not also using `--update`. It might even make sense to emit a warning in the code when doing this, but for now, I made it more clear in the docs.
I also clarified how `--use-server-modtime` can be useful in the `--update` section.
This was started by Fionera, finished off by Laura with fixes and more
docs from Nick.

This replaces the `sync.Pool` allocator with lib/pool. This
implements a pool of buffers of up to 64MB which can be re-used but is
flushed every 5 seconds.
If `--use-mmap` is set then rclone will use mmap for memory
allocations which is much better at returning memory to the OS.
The --no-traverse flag was not implemented when the new sync routines
(using the march package) was implemented.
This re-implements --no-traverse in march by trying to find a match
for each object with NewObject rather than from a directory listing.
This change allows remotes to be created on the fly without a config
file by using the remote type prefixed with a : as the remote name, Eg
:s3: to make an s3 remote.
This assumes the user is supplying the backend config via command line
flags or environment variables.
