mount: changed handling of volume name (Windows and OSX)

Fixes an issue on Windows where mounting the local filesystem in network mode failed when not using option --volname. Reason was that the volume name in network mode is a network share path in the basic UNC format, and characters that are invalid in regular file and directory names are also invalid in such a path. And the default volume name would typically include a '?', which is invalid, from the unc path of the local, e.g. "\\server\\? C Temp". The fix is to use an encoder to encode invalid characters such as '?' with the unicode equivalent, similar to how rclone encodes filesystem paths in normal operations, when mounting in network mode. Also performs some automatic cleanup of path separators, but in general, tries to be conservative on restrictions, and instead rely on --volname being set to something realistic. Existing strategy to replace the two characters ':' and '/' with space, regardless of mounting mode variant, was removed. For network mode the new approach handles these in a better way. Also the existing method did not apply at all when using the implicit network mode where volume names are taken from mountpath instead of volname option ("rclone mount remote:path/to/files \\cloud\remote"). For non-network mode they were not needed. Default volume names, when not specified by user, will be different with this change. See: #6234

-### Guidelines for a speedy merge
+Unit tests

- **Do** use [lib/rest](https://pkg.go.dev/github.com/rclone/rclone/lib/rest) if you are implementing a REST like backend and parsing XML/JSON in the backend.
- **Do** use rclone's Client or Transport from [fs/fshttp](https://pkg.go.dev/github.com/rclone/rclone/fs/fshttp) if your backend is HTTP based - this adds features like `--dump bodies`, `--tpslimit`, `--user-agent` without you having to code anything!
- **Do** follow your example backend exactly - use the same code order, function names, layout, structure. **Don't** move stuff around and **Don't** delete the comments.
- **Do not** split your backend up into `fs.go` and `object.go` (there are a few backends like that - don't follow them!)
- **Do** put your API type definitions in a separate file - by preference `api/types.go`
- **Remember** we have >50 backends to maintain so keeping them as similar as possible to each other is a high priority!

-## Adding a new s3 provider
-
-It is quite easy to add a new S3 provider to rclone.
-
-You'll need to modify the following files
-
- `backend/s3/s3.go`
-    - Add the provider to `providerOption` at the top of the file
-    - Add endpoints and other config for your provider gated on the provider in `fs.RegInfo`.
-    - Exclude your provider from generic config questions (eg `region` and `endpoint).
-    - Add the provider to the `setQuirks` function - see the documentation there.
- `docs/content/s3.md`
-    - Add the provider at the top of the page.
-    - Add a section about the provider linked from there.
-    - Add a transcript of a trial `rclone config` session
-        - Edit the transcript to remove things which might change in subsequent versions
-    - **Do not** alter or add to the autogenerated parts of `s3.md`
-    - **Do not** run `make backenddocs` or `bin/make_backend_docs.py s3`
- `README.md` - this is the home page in github
-    - Add the provider and a link to the section you wrote in `docs/contents/s3.md`
- `docs/content/_index.md` - this is the home page of rclone.org
-    - Add the provider and a link to the section you wrote in `docs/contents/s3.md`
-
-When adding the provider, endpoints, quirks, docs etc keep them in
-alphabetical order by `Provider` name, but with `AWS` first and
-`Other` last.
-
-Once you've written the docs, run `make serve` and check they look OK
-in the web browser and the links (internal and external) all work.
-
-Once you've written the code, test `rclone config` works to your
-satisfaction, and check the integration tests work `go test -v -remote
-NewS3Provider:`. You may need to adjust the quirks to get them to
-pass. Some providers just can't pass the tests with control characters
-in the names so if these fail and the provider doesn't support
-`urlEncodeListings` in the quirks then ignore them. Note that the
-`SetTier` test may also fail on non AWS providers.
-
-For an example of adding an s3 provider see [eb3082a1](https://github.com/rclone/rclone/commit/eb3082a1ebdb76d5625f14cedec3f5154a5e7b10).

-## Writing a plugin
+## Writing a plugin ##

 New features (backends, commands) can also be added "out-of-tree", through Go plugins.
 Changes will be kept in a dynamically loaded file instead of being compiled into the main binary.
 This is useful if you can't merge your changes upstream or don't want to maintain a fork of rclone.

-## Keeping a backend or command out of tree
-
-Rclone was designed to be modular so it is very easy to keep a backend
-or a command out of the main rclone source tree.
-
-So for example if you had a backend which accessed your proprietary
-systems or a command which was specialised for your needs you could
-add them out of tree.
-
-This may be easier than using a plugin and is supported on all
-platforms not just macOS and Linux.
-
-This is explained further in https://github.com/rclone/rclone_out_of_tree_example
-which has an example of an out of tree backend `ram` (which is a
-renamed version of the `memory` backend).
