Rework list ending data paths

There are now four modes to NodeParser. This mode is specified by the
NodeParserMode enum via a template argument.

Modes:
SchemaNode: will parse schema nodes.

CompleteDataNode: works exactly as the dataNode_ parser before. It will
parse data nodes.

IncompleteDataNode: works the same as CompleteDataNode, but allows
parsing a list without keys.

CompletionsOnly: in this mode, the parser only creates completions, and
doesn't do any actual parsing. This mode is needed when parsing a path
ending with a list without keys, with a trailing slash.
Example: /module:list/
After the path fragment and the trailing slash are parsed, no more node
parsing happens (because there's no more input). However, I still need
to generate completions. That's when I need to use CompletionsOnly.

PathParser now also has modes, they are similar to the NodeParser modes.
They are used to state what kind of path is supposed to be parsed.
