Jan Lindemann	0c732672ed	lib.FileContext: Add readdir() method ... FileContext offers get(), put(), unlink(), mkdir(), and stat(), but no way to list the entries of a directory, so consumers that need the names of the entries under a path in a context have no portable means to obtain them. Add readdir(), returning Iterable[str], following the _readdir() -> readdir() pattern used by the other operations: the public method chroots the path via _chroot() and delegates to the _readdir() hook, which raises NotImplementedError by default. Implement _readdir() in the context families: - Local._readdir(): os.listdir() - ExecContext._readdir(): runs ls -1A and splits the output into one entry per line; inherited by SSHClient and the other command-based contexts - Curl._readdir(): raises OSError with errno.ENOSYS Add unit tests covering Local (listing, hidden entries, missing directory) and Curl (ENOSYS).

Jan Lindemann	dc101a5a7f	lib.ec.ssh.Exec: Fix askpass script ... __init_askpass() embeds the password verbatim in a generated bash script, with a newline included inside the double quotes of the echo -n. The askpass program therefore always appends a newline to the password, and any password containing quotes or shell metacharacters either breaks the script or injects commands into it. Embed the password as base64 and decode it with printf piped into base64 -d, so the script is safe for any password and prints the password exactly, byte for byte. Make __del__() idempotent: it deletes the environment variables and the script file, so a second call, e.g. an explicit one followed by garbage collection, raises KeyError and FileNotFoundError. Add a unit test that executes the generated script and compares its output with the password byte for byte.
