Scalar utilities

Topics
	Scalar style helpers
	These functions are used by the emitter to choose a scalar style when a scalar does not have it set.
	Scalar charconv helpers
	These functions are used by the parser and emitter to convert scalars to and from chars.
	Scalar filter processors
	These are internal utilities used by ParseEngine to filter YAML scalars; normally there is no reason for a user to be manually using these classes.
