The SFTP protocol (and the golang sftp package) internally uses uint32 unix
time for expressing mtime. Hence it is a waste of memory to store it as 24-byte
time.Time data structure in long-lived data structures. So despite that the
golang sftp package uses time.Time as external interface, we can re-encode the
value back to the original format and save memory.

Before this change, rclone always expected --sftp-path-override to be
the absolute SSH path to remote:path/subpath which effectively made it
unusable for wrapped remotes (for example, when used with a crypt
remote, the user would need to provide the full decrypted path.)
After this change, the old behavior remains the default, but dynamic
paths are now also supported, if the user adds '@' as the first
character of --sftp-path-override. Rclone will ignore the '@' and
treat the rest of the string as the path to the SFTP remote's root.
Rclone will then add any relative subpaths automatically (including
unwrapping/decrypting remotes as necessary).
In other words, the path_override config parameter can now be used to
specify the difference between the SSH and SFTP paths. Once specified
in the config, it is no longer necessary to re-specify for each
command.

This allows using an external ssh binary instead of the built in ssh
library for making SFTP connections.
This makes another integration test target TestSFTPRcloneSSH:

Before this change we released the ssh connection back to the pool
before the upload was finished.
This meant that uploads were re-using the same ssh connection which
reduces throughput.
This releases the ssh connection back to the pool only after the
upload has finished, or on error state.
See: https://forum.rclone.org/t/sftp-backend-opens-less-connection-than-expected/40245
This introduces a new fs.Option flag, Sensitive and uses this along
with IsPassword to redact the info in the config file for support
purposes.
It adds this flag into backends where appropriate. It was necessary to
add oauthutil.SharedOptions to some backends as they were missing
them.
Fixes#5209
Implement a Partialuploads feature flag to mark backends for which
uploads are not atomic.
This is set for the following backends
- local
- ftp
- sftp

Before this change rclone used a normal SFTP rename if present to
implement Move.
However the normal SFTP rename won't overwrite existing files.
This fixes it to either use the POSIX rename extension
("posix-rename@openssh.com") or to delete the source first before
renaming using the normal SFTP rename.
This isn't normally a problem as rclone always removes any existing
objects first, however to implement non --inplace operations we do
require overwriting an existing file.
When using ssh-agent to hold multiple keys, it is common practice to configure
openssh to use a specific key by setting the corresponding public key as
the `IdentityFile`. This change makes a similar behavior possible in rclone
by having it parse the `key_file` config as the public key when
`key_use_agent` is `true`.
rclone already attempted this behavior before this change, but it assumed that
`key_file` is the private key and that the public key is specified in
`${key_file}.pub`. So for parity with the openssh behavior, this change makes
rclone first attempt to read the public key from `${key_file}.pub` as before
(for the sake of backward compatibility), then fall back to reading it from
`key_file`.
Fixes#6791
Fish is different from POSIX-based Unix shells such as bash,
and a bracketed variable references like we use for the
auto-detection echo command is not supported. The command
will return with zero exit code but produce no output on
stdout. There is a message on stderr, but we don't log it
due to the zero exit code:
fish: Variables cannot be bracketed. In fish, please use {$ShellId}.
Fixes#6552
If mkdir fails then before this change it would have thrown an
error.
After this change, if the error indicated that the directory
already exists then the error is not returned to the user.
This fixes a race condition when two rclone threads are trying to
create the same directory.
Windows shells like cmd and powershell needs to use different quoting/escaping
of strings and paths than the unix shell, and also absolute paths must be fixed
by removing leading slash that the POSIX formatted paths have
(e.g. /C:/Users does not work in shell, it must be converted to C:/Users).
Tries to autodetect shell type (cmd, powershell, unix) on first use.
Implemented default builtin powershell functions for hashsum and about when remote
shell is powershell.

strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.
