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.

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.

makes the following go strings functions available to be used in custom templates; contains, hasPrefix, hasSuffix
added documentation for exported funcs
Before this change, the maximum number of connections was set to 10.
This means that b2 could deadlock while uploading multipart uploads
due to a lock being held longer than it should have been.
Before this change the concurrency used for an upload was rather
inconsistent.
- if size below `--backend-upload-cutoff` (default 200M) do single part upload.
- if size below `--multi-thread-cutoff` (default 256M) or using streaming
uploads (eg `rclone rcat) do multipart upload using
`--backend-upload-concurrency` to set the concurrency used by the uploader.
- otherwise do multipart upload using `--multi-thread-streams` to set the
concurrency.
This change makes the default for the concurrency used be the
`--backend-upload-concurrency`. If `--multi-thread-streams` is set and larger
than the `--backend-upload-concurrency` then that will be used instead.
This means that if the user sets `--backend-upload-concurrency` then it will be
obeyed for all multipart/multi-thread transfers and the user can override them
all with `--multi-thread-streams`.

This makes the memory controls of the s3 backend inoperative and
replaced with the global ones.
--s3-memory-pool-flush-time
--s3-memory-pool-use-mmap
By using the buffered reader this fixes excessive memory use when
uploading large files as it will share memory pages between all
readers.
Fixes#7141
I ( @boukendesho ) have volunteered to maintain the snap package so
this adds it back into the installation instructions.
It will set a `snap` tag visible in `rclone version` so we know where
it came from for support queries.
From the Go docs:
"A `nil` map is equivalent to an empty map. [1]
Therefore, an additional nil check for `opts.ExtraHeaders` before the loop is
unnecessary because `opts.ExtraHeaders` is a `map`.

This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.
This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.
