2017-06-30Split CFDE_CSSTextBuf in two.Lei Zhang
For the external buffer use case, use a CFDE_CSSExtTextBuf instead. With the split, both text buffer implementations are simpler now. As a result, it becomes obvious where it never fails. Adjust callers accordingly.

The issue at hand is caused by a raw pointer rather than a retained pointer in InheritedData::m_pFontFamily. But the larger issue is that it's bad to Get() raw pointers from these, especially when its so cheap to pass them by const reference. One reason to Get() a raw pointer is to aid in down-casts, so add a helper to CFX_RetainPtr to give us downcasted retained pointers.
