Document the qintptr for public usage

The QAbstractSocket API has been already using this as a return type. Hence,
this has already been exposed to the public API users, anyhow.

http://qt-project.org/doc/qt-5.0/qtnetwork/qabstractsocket.html#socketDescriptor

A minor mistake has also been fixed in this commit at the quintptr section.
