2017-04-18Cleanup XML buffer codeDan Sinclair
This CL removes the CXML_DataStmAcc class which was unused and moves the CXML_DataBufAcc to a separate file. This removes the use of the IFX_BufferedReadStream as the parent class and removes default implemented methods.

2017-04-17Fix buffer management issues in CFX_SAXReader.Tom Sepez
Re-write to use std::vectors rather than self-managed buffers. Includes test case that breaks before patch. Formerly, we had two independent buffers whose position were tracked by the same variable, assuming that only one was being written to at a given time. This is a bad idea because it's easy to forget to zero the index when switching buffers, and start indexing into one using previously computed offsets from the other. Additionally, there were cases where the location of a partial entity wasn't discarded when switching states thus clearing the buffer tracking said entity.

In CPDF_TrueTypeFont, an index of 0 indicates a freetype failure, which means we should try to find the glyph from a fallback font. - Improve the fallback glyph calculation by going from original font charcode to unicode to fallback font charcode. - Consider the m_ExtGID on Mac when deciding the fallback.
