d0d41fe847 rclone config redacted: implement support mechanism for showing redacted config
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

2cd85813b4 sftp: don't check remote points to a file if it ends with /
This avoids calling stat on the root directory which saves a call and
some servers don't like.

e6e6069ecf sftp: don't stat directories before listing them
Before this change we ran stat on the directory to see if it existed.

Not only is this inefficient it isn't allowed by some SFTP servers.

aaacfa51a0 sftp: fix move to allow overwriting existing files
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.

sftp: fix using key_use_agent and key_file together needing private key 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`.

1392793334 sftp: auto-detect shell type for fish
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}.

sftp: fix directory creation races
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.

b4091f282a sftp: add support for about and hashsum on windows server
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.

0537791d14 sftp: Fix performance regression by re-enabling concurrent writes #5197
Betweeen rclone v1.54 and v1.55 there was an approx 3x performance
regression when transferring to distant SFTP servers (in particular
rsync.net).

This turned out to be due to the library github.com/pkg/sftp rclone
uses. Concurrent writes used to be enabled in this library by default
(for v1.12.0 as used in rclone v1.54) but they are no longer enabled
(for v1.13.0 as used in rclone v1.55) for safety reasons and it is
necessary to enable them specifically.

The safety concerns are due to the uncertainty as to whether writes
come in order and whether a half completed file might have holes in
it. This isn't a problem for rclone since a) it doesn't restart
uploads and b) it has a post-transfer checksum test.

This change introduces a new flag `--sftp-disable-concurrent-writes`
to control the feature which defaults to false, meaning that
concurrent writes are enabled as in v1.54.

However this isn't quite enough to fix the problem as the sftp library
needs to be able to sniff the size of the stream from the reader
passed in, so this also adds a `Size` interface to the reader to
enable this. This involved a patch to the library.

The library was reverted to v1.12.0 for v1.55.1 - this patch installs
v1.13.0+master to fix the Size interface problem.

a3fcadddc8 sftp: close idle connections after --sftp-idle-timeout (1m by default)

Idle SFTP connections were closed after 1 minute. However due to the
way SSH multiplexes connections over a single SSH connection this
meant that if uploads or downloads went on for more than one minute
they failed with "EOF errors" as their underlying connection was
closed.

This fixes the problem by not clearing idle connections if there are
any transfers in progress.

9ee3ad70e9 sftp: fix SetModTime stat failed: object not found with --sftp-set-modtime=false
Some sftp servers don't allow the user to access the file after upload.

In this case the error message indicates that using
--sftp-set-modtime=false would fix the problem. However it doesn't
because SetModTime does a stat call which can't be disabled.

    Update SetModTime failed: SetModTime stat failed: object not found

After upload this patch checks for an `object not found` error if
set_modtime == false and ignores it, returning the expected size of
the object instead.

It also makes SetModTime do nothing if set_modtime = false
