QByteArray: deprecate QT_NO_CAST_FROM_BYTEARRAY-protected operators

The QByteArray::operator const {char,void}*() implicit
conversions are a source of subtle bugs, so they right-
fully can be disabled with QT_NO_CAST_FROM_BYTEARRAY.

  const char *d = qstring.toLatin1(); // implicit conversion
  while ( d ) // oops: d points to freed memory
     // ...

But almost no-one ever enabled this macros in the wild
and many were bitten by these implicit conversions, so
this patch deprecates them.

I would have liked to remove them completely, but there
are just too many occurrences even in Qt itself to hope
to find all conditionally-compiled code that uses these.

Also fixes all code that needs to compile under
QT_NO_DEPRECATED (in qmake/, src/tools/).

I984706452db7d0841620a0f64e179906123f3849 separately
deals with the bulk of changes in src/ and examples/.

Depends on I5ea1ad3c96d9e64167be53c0c418c7b7dba51f68.
