Starting with go1.22 the standard os.MkdirAll has improved its handling of volume names,
and as part of that it now stops recursing into parent directory if it is a volume name
(see: cd589c8a73).
This is similar to what was our main change and reason for creating a custom version. When
building with go1.22 or newer we can therefore stop using our custom version, with the
advantage that we automatically get current and future relevant improvements from golang.
To support building with go1.21 the existing custom version is still kept, and therefore
also our wrapper function file.MkdirAll - but it now just calls os.MkdirAll with go1.22
or newer on Windows.
See #5401, #6420 and acf1e2df84 for details about the
creation of our custom version of MkdirAll.
We upgraded our minimum Go version in commit ca24447090. We can now use
the built-in `min` and `max` functions directly.

There were a lot of instances of this lint error
printf: non-constant format string in call to github.com/rclone/rclone/fs.Logf (govet)
Which were fixed by re-arranging the arguments and adding "%s".
There were quite a few genuine bugs which were found too.
reflect.SliceHeader is deprecated, however the replacement gives a go
vet warning so this disables the lint warning in one use of
reflect.SliceHeader and replaces it in the other.
This prevents an `rclone rcd` server from prematurely going into the
'deactivating' state, which was causing systemd to kill it with a
SIGABRT after the stop timeout.
Fixes#7540
The vfs use the hardcoded OS encoding when creating temp file,
but decode it with encoding for the local filesystem (--local-encoding)
when copying it to remote.
This caused failures when the filenames contained special characters.
The hardcoded OS encoding is now used uniformly.
On Windows, this change includes the `FILE_FLAG_BACKUP_SEMANTICS` in
all calls to `CreateFile`.
Adding this flag allows is useful when rclone is running within a
security context that has `SeBackupPrivilege` and/or `SeRestorePrivilege`
token privileges enabled.
Without this flag, rclone cannot properly leverage special security
groups such as Backup Operators who possess the these privileges.
See: https://forum.rclone.org/t/rclone-sebackupprivilege-file-flag-backup-semantics/45339
See: https://github.com/rclone/rclone/pull/7877.
When an external OAuth flow is being used (i.e. a client ID and an
OAuth token are set in the config), a client secret should not be set.
If one is, the server may reject a token refresh attempt.
But there's no way to clear out a backend's default client secret via
configuration, since empty-string config values are ignored.
So instead, when a client ID is set, we should clear out any default
client secret, since it wouldn't apply anyway.
Windows webdav does an OPTIONS request on the root even when given a
path and if we return 404 here then Windows refuses to use the path.
This patch allows OPTIONS requests only on the root to fix this.
This affects all the HTTP servers.
Before this change it wasn't possible to see where transfers were
going from and to in core/stats and core/transferred.
When use in rclone mount in particular this made interpreting the
stats very hard.
the field `raw` of `oauth2.Token` may be an uncomparable type(often map[string]interface{}), causing `*token != *ts.token` expression to panic(comparing uncomparable type ...).
the semantics of comparing whether two tokens are the same can be achieved by comparing accessToken, refreshToken and expire to avoid panic.
Before this change multi-thread copies using the FTP backend used to error with
551 Error reading file
This was caused by a spurious error being reported which this code silences.
Fixes#7532
See #3942
When f.opt.MaxAge == 0, f.db is never set, however several methods later assume
it is set and attempt to access it, causing an invalid memory address error.
This change fixes the issue in a few spots (there may still be others I haven't
yet encountered.)
Before this change, calling the `oauthutil.NewRenew` func may
cause goroutine leaks.
This change adds a `Shutdown` method to allow the caller to exit
the goroutine to avoid leaks.

In ths security related issue the go1.21.4 stdlib changed the parsing
of volume names on Windows.
https://github.com/golang/go/issues/63713
This had the consequences of breaking the MkdirAll tests which were
looking for specific error messages which changed and using invalid
paths.
In particular under go1.21.3:
filepath.VolumeName(`\\?\C:`) == `\\?\C:`
But under go1.21.4 it is:
filepath.VolumeName(`\\?\C:`) == `\\?`
The path `\\?\C:` isn't actually a valid Windows path. I reported this
as a FYI bug upstream - I'm not expecting it to be fixed.
See: https://github.com/golang/go/issues/64101
makes the following go strings functions available to be used in custom templates; contains, hasPrefix, hasSuffix
added documentation for exported funcs
