This CL moves the switch from CFX_XMLParse::Parse into
CFX_XMLParser::DoSyntaxParse. This means all the work to build the tree
is now done in one place instead of spread between the two methods.

This CL adds a CFX_XMLDocument to act as the XML node container. All
nodes are now owned by the document and the document is returned by the
CFX_XMLParser.
Classes which parse XML files now store the document instead of the root
node.

When we extract the text data we need to make sure we clear any
entity start positions, otherwise our entity extraction will go badly.

This CL removes the m_CurNodeType member from CFX_XMLParser. This was,
essentially, duplicating the m_XMLNodeTypeStack. We now use the top() of
the stack element to find the same information.

This CL removes the usage of CFX_BlockBuffer from CFX_XMLParser. The
block buffer has been replaced by a vector which is emptied out after
the characters are removed. This should use less memory when parsing XML
as the block buffer was previously storing all text characters seen in
the file.

This CL converts the CFX_XMLParser to use the FXSYS methods to convert
decimal and hex chars during entity conversion.

The methods to get a piece of data from the text buffer are all
identical. This CL collapses them all into a single GetTextData method.

This CL converts CPDF_Metadata to use the CFX_XML classes instead of
CXML classes. This also moves the CFX_XML classes from being XFA only to
being used everywhere.

The CFX_XMLParser was a wrapper around the CFX_XMLSyntaxParser. This CL
merges the SyntaxParser into protected/private methods if the XMLParser.
