Since this is always set to true on the non-default constructor and
subsequently never modified, it is somewhat pointless. Furthermore,
there are arguably no invalid relative paths.
This patch adds two new methods to LexicalPath. LexicalPath::append
appends a new path component to a LexicalPath, and LexicalPath::join
constructs a new LexicalPath from one or more components.

If the prefix path is just a slash the LexicalPath was removing too many
characters. Now only remove an extra character if the prefix is not just
the root path.
And move canonicalized_path() to a static method on LexicalPath.
This is to make it clear that FileSystemPath/canonicalized_path() only
perform *lexical* canonicalization.
