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.
Before this fix, rclone only generated an RSA server key when the user
didn't supply a key.
However the RSA server key is being deprecated as it is now insecure.
This patch generates an ECDSA server key too which will be used in
preference over the RSA key, but the RSA key will carry on working.
Fixes#5671
This replaces built-in os.MkdirAll with a patched version that stops the recursion
when reaching the volume part of the path. The original version would continue recursion,
and for extended length paths end up with \\? as the top-level directory, and the error
message would then be something like:
mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
Before this change, if one connection was authenticating this would
block any others from authenticating.
This was due to ssh.NewServerConn not being called in a go routine
after the Accept call.
This is fixed by running the ssh authentication in a go routine.
Thanks to @FiloSottile for advice on how to fix this.

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.
This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
Before this change the sftp handler returned a nil error for unknown
operations which meant the server crashed when one was encountered.
In particular the "Readlink" operations was causing problems.
After this change the handler returns ErrSshFxOpUnsupported which
signals to the remote end that we don't support that operation.

- 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.
