Fixes for QByteArrayMatcher
Copy constructor and assignment operator lose data: pointer to content and the length of content also need to be copied over. QByteArrayMatcher::pattern() would return a null byte array if instance was initialized with c-string. Changed default constructor to explicitly initialize pattern length to zero. The bug in the assignment operator is a regression against 4.4.3. Task-number: 251958 Reviewed-by: MariusSO Reviewed-by: paul
