QDoc cannot handle custom namespace in QtNFC and QtBluetooth

Run the following:

cd qtconnectivity
git checkout dev
cd src/nfc
make html_docs

Observe the QNdefMessage related errors.

qdoc does not recognize the QNdefMessage class declaration. The only known workaround is to append the QNdefMessage class declaration for a second time inside the header:

class Q_NFC_EXPORT QNdefMessage: public List<QNdefRecord>
{
...
}

#ifdef Q_QDOC
//same as above
class Q_NFC_EXPORT QNdefMessage: public List<QNdefRecord>
{
...
}
#endif

This uses qdoc from qtbase (dev branch -> 1c901913c0af79b2bbde1b9da71f5267cb4fc76a)
