Passing zero as size parameter to QAbstractSocketEngine::write() has
unspecified behavior, at least for TCP sockets. This could happen on
flush() when writeBuffer is empty or on writeData() with size 0. Avoid
by explicitly checking against zero size.

DirectWrite: Fix advances being scaled to 0
Since 131eee5cd, the stretch of a font can be 0, meaning
"whatever the font provides". In combination with ec7fee96,
this would cause advances in the DirectWrite engine to be scaled to
0, causing the QRawFont test to fail.

According to documentation, waitForReadyRead() returns 'true' if
the readyRead() signal is emitted and there is new data available
for reading. Thus, waitForReadyRead() is being blocked in cycle
until canReadNotification() will return 'true'. This patch
adjusts canReadNotification() to return 'true' only when new data
arrives on buffered socket that ensures waitForReadyRead() to
succeed correctly.

While connecting, the socket goes through the HostLookupState. In
this state, the socket engine is not yet created, unless the socket
had previously been bound. When it has been bound, we should keep
the socket engine even if the user initiates a delayed close by
using the write()+close() sequence.

To avoid infinite loop on unbuffered socket, previous implementation
always disabled the read notifications before emitting a readyRead()
signal. So, it's very likely that the socket will toggle the state of
notifier twice (on->off->on) in one notification cycle.
This patch prevents this unnecessary toggling by deferring the
notification disabling in canReadNotification() to the next
notification cycle.

Read notifications on a buffered socket are enabled all the time while
the socket is connected unless the buffer size limit is reached. To
enable the read notifier again, the user needs to read the data or
enlarge the buffer with a setReadBufferSize() call.
According to that scenario, it's very likely that the socket will
toggle the state of notifier twice (on->off->on) in one notification
cycle. Also, use of the readyRead() signal with a queued connection
leads to the same problem.
This patch prevents this unnecessary toggling by:
- unconditionally setting the notifier's state in setReadBufferSize();
- deferring the notification disabling in canReadNotification()
to the next notification cycle.

writeToSocket() to handle disabling the notifications in all cases.
