This fixes the Root() returned by the backend when it has returned
fs.ErrorIsFile.
Before this change it returned a root which included the file path.
Because Root() was wrong this caused the detection of the file being
moved over itself check to fail.
This adds an integration test to check it for all backends.

Set this automatically for any backend which implements UnWrap and
manually for combine and union which can't implement UnWrap but do
overlay other backends.
Before this change, when Object.Update was called in the drive
backend, it overwrote the remote with that of the object info.
This is incorrect - the remote doesn't change on Update and this patch
fixes that and introduces a new test to make sure it is correct for
all backends.
This was noticed when doing Update of objects in a nested combine
backend.

This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
Add an encoding test to make sure backends can deal with a URL encoded
path name. This is a fairly common failing in backends and has been an
intermittent problem with onedrive itself.
Before this change we checked that features.ReadMimeTime was set if
and only if the Object.MimeType method was implemented.
However this test is overly general - we don't care if Objects
advertise MimeType when features.ReadMimeTime is set provided that
they always return an empty string (which is what a wrapping backend
might do).
This patch implements that logic.
This changes the interface to NewObject so that if NewObject is called
on a directory then it should return fs.ErrorIsDir if possible without
doing any extra work, otherwise fs.ErrorObjectNotFound.
Tested on integration test server with:
go run integration-test.go -tests backend -run TestIntegration/FsMkdir/FsPutFiles/FsNewObjectDir -branch fix-stat -maxtries 1
Includes adding support for additional size input suffix Mi and MiB, treated equivalent to M.
Extends binary suffix output with letter i, e.g. Ki and Mi.
Centralizes creation of bit/byte unit strings.
Backends for which additional config is detected (in the config string
or on the command line or as environment variables) will gain a suffix
`{XXXXX}` where `XXXX` is a base64 encoded md5hash of the config
string.
This fixes backend caching with config string remotes.
This much requested feature now works properly:
rclone copy -vv drive,shared_with_me:file.txt drive:
This is implemented as a state machine parser so it can emit sensible
error messages.
It does not use the connection strings elsewhere in rclone yet - see
subsequent commits.
An optional fuzzer is implemented for the Parse function.
This is done by making fs.Config private and attaching it to the
context instead.
The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.
