2018-08-07Speculative fix for null deref above ThrowNoDefaultPropertyExceptionTom Sepez
Avoid possibility of an unterminated string or nullptr by avoiding stringviews, since the non-view classes copy and always provide a suitable result. Always use %ls and widestrings in wprintf() variants, since that combination is consistent across our platforms (%s, %S, etc. have idiosyncracies).

2018-08-03Make CFX_XMLParser less permissiveRyan Harrison
Currently the parser will accept arbitrary garbage before the first element begins. This is causing issues with ClusterFuzz since it generates a lot of trash inputs which take a long time to parse inspite of being invalid. This CL adds in a check of how deep the parse is when dealing with text, and if it is at the top level scope, then only accept the beginning of the root node.
