    matroskadec: Add sizes to forward declarations
    
    Unknown-length elements end when an element not allowed in them, but
    allowed at a higher level is encountered. In order to check for this,
    c1abd95a added a pointer to every syntax level's parent to each
    EbmlSyntax. Given that the parent must of course also reference the
    child in order to be able to enter said child level, one needs to use
    forward declarations.
    These forward declarations constitute tentative definitions and tentative
    definitions with internal linkage (like our syntaxes) must not be an
    incomplete type. Yet they were an incomplete type and while GCC and
    Clang did not even warn about this (on default warning levels), it
    broke compilation with MSVC. Therefore this commit adds the sizes.
