3faa84b47c combine,compress,crypt,hasher,union: support wrapping backends with PartialUploads 
This means that, for example, wrapping a sftp backend with crypt will
upload to a temporary name and then rename unless disabled with
--inplace.

09a408664d fs: create Overlay feature flag to indicate backend wraps others 
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.

c2baacc0a4 union: fix uploading files to union of all bucket based remotes 
Before this fix, if uploading to a union consisting of all bucket
based remotes (eg s3), uploads failed with:

    Failed to copy: object not found

This was because the union backend was relying on parent directories
being created to work out which files to upload. If all the upstreams
were bucket based backends which can't hold empty directories, no
directories were created and the upload failed.

This fixes the problem by returning the upstreams used when creating
the directory for the upload, rather than searching for them again
after they've been created.

This will also make the union backend a little more efficient.

Fixes #6170

5dd51e6149 union: fix deadlock when one part of a multi-upload fails 
Before this fix, rclone would deadlock when uploading two files at
once, if one errored. This caused the other file to block in the multi
reader and never complete.

This fix drains the input buffer on error which allows the other
upload to complete.

e43b5ce5e5 Remove github.com/pkg/errors and replace with std library version 
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.

bb0c4ad2d8 union: fix rename not working with union of local disk and bucket based remote 
Before this change the union's feature flags were a strict AND of the
underlying remotes. This means that a union of a local disk (which can
Move but not Copy) and a bucket based remote (which can Copy but not
Move) could neither Move nor Copy.

This fix advertises Move in the union if all the remotes can Move or
Copy. It also implements Move as Copy+Delete (like rclone does
normally) if the underlying union does not support Move.

This enables renames to work with unions of local disk and bucket
based remotes expected.

Fixes #5632

23c826db52 union: fix writing with the all policy - fixes #4534 
Before this change writing with the all policy deadlocked while
uploading.

This change fixes the problem by fixing the multi reader, closing the
pipes at the correct time with the correct error. This is factored
into a new function as it was used twice.

This patch also adds a new test which tests the all policies.

a2afa9aadd fs: Add directory to optional Purge interface - fixes #1891

- add an additional integration test to test for the feature
- use the new feature in operations.Purge

Many of the backends had been prepared in advance for this so the
change was trivial for them.

f78cd1e043 Add context propagation to rclone 
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions

Context propagation is needed for stopping transfers and passing other
request-scoped values.

b26276b416 union: fix poll-interval not working - fixes #2837 
Before this change the union remote was using whether the writable
union could poll for changes to decide whether the union mount could
poll for changes.

The fix causes the union backend to signal it can poll for changes if
**any** of the remotes can poll for changes.
