    Issue 2507: Stop the entanglement of context properties and grob  
property internals

    This introduces a semi-opaque structure Grob_properties meeting the
    predicate ly:grob-properties? that is algorithmically handled at the C++
    level via a wrapper structure Grob_property_info.

    Encapsulating grob properties in that manner reduces the potential for
    clashes and makes it easier to change algorithms and/or internal
    representation.

    While the principal distinction between context properties (one value
    per context) and context-based grob property templates (one stack per
    context) remains, at least the separation of the handling is more
    pronounced.
