        fdo#52028: sw: let text formatting ignore RSID in automatic styles
    
        A suprising regression from 062eaeffe7cb986255063bb9b0a5f3fb3fc8e34c:
        The RSID text attributes that are inserted for every user-inserted text
        cause the text formatting (SwAttrIter) to create a lot more text portions,
        and the portion breaks make font kerning impossible.
    
        This is the only way i can think of to fix this problem; alternatives that
        don't work are splitting the RSID out of the AUTOFMT hint into a separate
        one and combining them in the sw UNO wrappers (fails because
        SwXAutoStylesEnumerator actually does need to enumerate every AUTOFMT
        including RSID), trying to detect and ignore them just in the text
        formatting (the SwAttrIter cannot easily/cheaply detect when it's allowed
        to skip), and having an internal subdivision inside the AUTOFMT hint (one
        subsection for every RSID change) (which does not work because it cannot
        ignore RSID-only AUTOFMTs completely).
    
        Solve the problem with 2 additional flags on AUTOFMT and CHARFMT
        attributes: FormatIgnoreStart and FormatIgnoreEnd, which indicate to
        SwAttrIter::GetNextAttr() that the start or end of the hint should be
        ignored, so that effectively it is merged with the preceding/subsequent
        hint.  Of course the UNO API does not respect the flags so we can store
        the RSIDs in automatic styles.
    
        The flags are maintained in SwpHints::MergePortions, which detects both
        RSID-only AUTOFMT hints (which can be ignored completely), and the
        situation of N CHARFMT hints + AUTOFMT hint vs. N CHARFMT hints +
        AUTOFMT hint where the AUTOFMT hints differ only in their RSID attribute.
    
        This means that MergePortions needs to be called more often now, in cases
        where the ignore flags may have been invalidated, such as:
        - insertion of text with possible DontExpand flag set on hints
        - deletion of hints
        - SETATTR_NOHINTADJUST mode
