Use URLPathEscapeAll instead of URLPathEscape for path encoding.
URLPathEscape relies on Go's url.URL.String() which only minimally
escapes paths - reserved sub-delimiter characters like semicolons and
equals signs pass through unescaped. Per RFC 3986 section 3.3, these
characters must be percent-encoded when used as literal values in
path segments.
Some WebDAV servers (notably dCache/Jetty) interpret unescaped
semicolons as path parameter delimiters, which truncates filenames
at the semicolon position. URLPathEscapeAll encodes everything
except [A-Za-z0-9/], which is safe for all servers.
Fixes#9082
Tar files created from the current directory (e.g. tar -czf archive.tar.gz .)
produce entries prefixed with "./". When extracting, rclone's character
encoding replaces the "." with a full-width dot (U+FF0E), creating a
spurious directory instead of merging into the destination root.
Strip the leading "./" from NameInArchive before processing. Only "./"
is stripped specifically to avoid enabling path traversal attacks via
"../".
