When determining if to recurse into a node, get_node_by_path does not
check if the length of each node name is equal. If searching for
/foo/baz, this can result in recursing into /foobar because
strneq("foo", "foobar", 3) is true.
This can result in a reference to /foo/baz to be incorrectly set to
/foobar/baz. A test for this was added.

At present, the lexer token for references to a path doesn't permit a
reference to the root node &{/}. Fixing the lexer exposes another bug
handling this case.
This patch fixes both bugs and adds testcases.

This patch extends dtc syntax to allow references (&label, or
&{/full/path}) directly within property definitions, rather than
inside a cell list. Such references are expanded to the full path of
the referenced node, as a string, instead of to a phandle as
references within cell lists are evaluated.
A testcase is also included.
