2023-12-17ssh/sftp: implement method MkdirAll on ClientShulhan
The MkdirAll create directory on the server, from left to right. Each directory is separated by '/', where the left part is the parent of the right part. This method is similar to [os.MkdirAll].
2023-12-17ssh/sftp: fix Stat on empty remote file nameShulhan
The implementation of SSH server for Stat is not consistent with the RFC. The RFC mentioned that An empty path name is valid, and it refers to the user's default directory (usually the user's home directory). But this only working on some command, like Mkdir, but not Stat.

2023-12-13all: fix linter warnings reported by reviveShulhan
There are some reports that I disagree with revive, in example, code should not declare the type after variables. In my opinion, on some cases, declaring the type make the code more readable and explicit. Since I did not want to add new configuration file, we changes it and follow revive for now.

The Close method close the client sftp session and release all its resources.
2023-09-24ssh/sftp: rename method Close to CloseFileShulhan
Since the method accept FileHandle, that is returned from OpenFIle, then the method should changes with the same suffix. This is also to make the method ambigous later when we add Close method to close clinet connection.

This changes check and return an error if * the server does not support sftp subsystem as ErrSubsystem * the client does not support the server version as ErrVersion Some response status code from server actually can be mapped to predefined errors from standar package, in this case * io.EOF for SSH_FX_EOF (status code 1) * fs.ErrNotExist for SSH_FX_NO_SUCH_FILE (status code 2) * fs.ErrPermission for SSH_FX_PERMISSION_DENIED Other errors are handled by wrapping ErrXxx variable withresponse message.
