This PR updates existing backends to implement the `IRenameEnabledBackend` interface, allowing for more efficient file renaming operations. The implementation varies by backend, with some using native rename operations and others falling back to copy-and-delete patterns.
This PR adds a dynamic property so a backend can signal if it supports streaming, based on the settings.
This is currently used for the File backend, so that toggling `--use-move-for-put` will disable streaming on the backend instead of relying on the `--disable-streaming-transfers` flag.
This PR moves the check from the FTP backend into shared code, so all backends will now check for read/write permissions when using the "Test" button.
For situations where write permissions are not required (like restore or verify) there is a flag on the v2 API that indicates if the connection was established, so the UI can show a message suggesting that it is possible to proceed, if the current UI operation does not require write permissions.
This fixes#2473
This addresses the issue described on
https://github.com/duplicati/duplicati/issues/6005
If a PureFTP server is detected, a warning is issued when executing server file listing.
The parameter`ignore-pureftpd-limit-issue` allows the warning to be suppressed.
In the event of an effective truncation, it will throw an exception and that cannot be suppressed as incomplete listing can lead to misleading backup/restore operations.
This PR adds a unified way of supplying timeouts to each of the backends.
It also adds an opt-in way of adding commonly used options, so parsing and usage can be standardized across multiple backends.
This PR is the final change, where all backends are now purely implemented with async interfaces.
The code changes here replace the LIST call with an async version. This affect all backends (and then some) but the changes are mostly mechanical rewrites of the code.
In many places, the backeds were already prepared for async output, in other some glue was needed.
To reduce the scope of this change, some backends simply report a synchronous result as an async list.

* More nullable fixes
* Fixed the overwrite issue
* Fixed additional nullability issues
* Removed additional nullability issues
* More nullability fixes and added some xmldoc
* Added more xmldocs and removed an unused argument
* Removed more warnings
Changed the strategy to use absolute paths for all operations, to avoid cases where a silent reconnect would end up in a different folder.
Add backwards compatible option to use CWD style relative operations.
Added support for detecting the SSL certificate hash when there is a certificate error.
With this change, ftp-passive, ftp-regular and use-ssl parameters found on existing FTP Backend configurations will be respected and exhibit the same behavior. They are marked as deprecated so they will issue warning messages when used prompting users to refer to new parameters.
For this change, what was known as the alternate FTP client which uses FluentFTP library now officially replaces the FTP Backend which still used the deprecated FtpWebrequest.
To mantain compatibility with existing configurations, both ftp and aftp targets and configuration prefixes are accepted.
