2018-09-18Transfer ownership of nodes to top-level XML docRyan Harrison
For XFA, XML nodes are owned by the XML doc that they were created by, but references to them are stored elsewhere. For a PDF document there is one top-level XML document created and retained when the initial XFA XML is parsed. Another can be created if loadXML is called by JS. In the existing code the XML doc that owns the newly created nodes is local to loadXML. So the nodes are destroyed right after putting refernces to them into the main XFA data structures. This CL adds in a method to transfer ownership of the XML nodes from one doc to another, and uses it to correctly retain the newly created nodes, by having them owned by the top-level XML doc.

2018-08-08Move ByteString::FromUnicode() to WideString::ToDefANSI()Tom Sepez
Turns out that "FromUnicode" is misleading in that, on linux, it simply removes any characters beyond 0xFF and passes the rest unchanged, so no unicode decoding actually takes place. On Windows, it passes it into the system function specifying FX_CODEPAGE_DefANSI, converting it into the so-called "default ANSI code plane", passing some characters, converting others to '?' and still others to 'A'. Either way, nothing resembling UTF8 comes out of this, so pick a better name. These now immediately look suspicious, so a follow-up CL will see which ones should really be WideString::UTF8Encode() instead. Making this a normal method on a widestring rather than a static method on a bytestring feels more natural; this is parallel to the UTF8Encode and UTF16LE_Encode functions. Add a test that shows these conversions.
