bbddadbd04 sftp: remember entered password in AskPass mode 
As reported in

  https://github.com/rclone/rclone/issues/4660#issuecomment-705502792

After switching to a password callback function, if the ssh connection
aborts and needs to be reconnected then the user is-reprompted for their
password.  Instead we now remember the password they entered and just give
that back.  We do lose the ability for them to correct mistakes, but that's
the situation from before switching to callbacks.  We keep the benefits
of not asking for passwords until the SSH connection succeeds (right
known_hosts entry, for example).

This required a small refactor of how `f := &Fs{}` was built, so we can
store the saved password in the Fs object

9e925becb6 sftp: defer asking for user passwords until the SSH connection succeeds 
Issue: 4660
    https://github.com/rclone/rclone/issues/4660

Unexpected side effect: a wrong password allows for the user to retry!

6dc28ef50a sftp: Allow user to optionally check server hosts key to add security 
Based on Issue 4087
  https://github.com/rclone/rclone/issues/4087

Current behaviour is insecure.  If the user specifies this value then we
switch to validating the server hostkey and so can detect server changes
or MITM-type attacks.

17acae2b00 sftp: allow cert based auth via optional pubkey 
Discussion at
  https://forum.rclone.org/t/ssh-certificate-based-authentication-does-not-work/19222

Basically we allow the user to specify their own public key cert rather
than letting the SSH client extract the pubkey from the private key.
This allows certificate based authentication to work.

fefcbf60fa sftp: use the absolute path instead of the relative path 
Before this change rclone used the relative path from the current
working directory.

It appears that WS FTP doesn't like this and the openssh sftp tool
also uses absolute paths which is a good reason for switching to
absolute paths.

This change reads the current working directory at startup and bases
all file requests from there.

f9306218f8 sftp: Fix SSH key PEM loading 
For SSH authentication, `key_pem` should both override `key_file`
and not require other SSH authentication methods to be set.

Prior to this fix, rclone would attempt to use an ssh-agent
when `key_pem` was the only SSH authentication method set.

Fixes #4240

e4f1e19127 sftp: fix post transfer copies failing with 0 size when using set_modtime=false 
Before this change we early exited the SetModTime call which means we
skipped reading the info about the file.

This change reads info about the file in the SetModTime call even if
we are skipping setting the modtime.

5f822f2660 sftp: fix "failed to parse private key file: ssh: not an encrypted key" error 
This error started happening after updating golang/x/crypto which was
done as a side effect of:

3801b8109 vendor: update termbox-go to fix ncdu command on FreeBSD

This turned out to be a deliberate policy of making
ssh.ParsePrivateKeyWithPassphrase fail if the passphrase was empty.

See: https://go-review.googlesource.com/c/crypto/+/207599

This fix calls ssh.ParsePrivateKey if the passphrase is empty and
ssh.ParsePrivateKeyWithPassphrase otherwise which fixes the problem.

a7d65bd519 sftp: add --sftp-skip-links to skip symlinks and non regular files - fixes #3716 
This also corrects the symlink detection logic to only check symlink
files.  Previous to this it was checking all directories too which was
making it do more stat calls than was necessary.

a1840f6fc7 sftp: add missing interface check and fix About #3257 
This bug was introduced as part of adding context to the backends and
slipped through the net because the About call did not have an
interface assertion in the sftp backend.

I checked there were no other missing interface assertions on all the
optional methods on all the backends.

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.

f3f48d7d49 Implement new backend config system 
This unifies the 3 methods of reading config

  * command line
  * environment variable
  * config file

And allows them all to be configured in all places.  This is done by
making the []fs.Option in the backend registration be the master
source of what the backend options are.

The backend changes are:

  * Use the new configmap.Mapper parameter
  * Use configstruct to parse it into an Options struct
  * Add all config to []fs.Option including defaults and help
  * Remove all uses of pflag
  * Remove all uses of config.FileGet
