QJsonDocument::fromRawData: Fix out-of-bounds access
This method takes a pointer+size pair, but begins reading through the pointer
without first checking the size parameter. Fixed by checking the size parameter.
A new test case is added with an empty binary json file. Although the test does
not fail under normal conditions, the problem can be detected using valgrind or
AddressSanitizer.
