This is near to the internal Qt PIMPL style. Also it will allow
to use QIODevicePrivate is more smoothly in next patches.
Tested on Windows 8, Linux, OSX 10.9 with on-board serial port.

After calling the WriteFile() function, QSP::bytesToWrite() should
return zero, but did return the size of writeBuffer.
On Windows, we must not to cut a size of the writeBuffer until the
asynchronous write operation has completed. So we need to make use of an
additional actualBytesToWrite variable, the value of which is increased
when new data is added to the writeBuffer, and decreased after calling
the WriteFile() function.
This change also entails the modification of the QSP::writeData() method
and deleting the QSP::startWriting() method. Now all platform-dependent
code (related to startWriting(), and to copying of memory to
writeBuffer) resides in the new QSP::writeData() method. But this
modification does not change the behavior on platforms other than Windows.
Tested on Windows with the virtual com0com serial ports using Qt5.

In case the read buffer has a limited size then are impossible to read
remainder which is still can be in driver's queue, since no readyRead
signal emmitted and reading are stalled.
Problem is that Windows does not fire the EV_RXCHAR event in case a
driver's queue has ready to read remainder; this event will be triggered
only when a new data are received.
The solution is to start of asynchronous read operation for reading of
possible remainder from the queue after doing QSP::read() from the user.
Besides is necessary to meet conditions:
- do not start reading in case a reading already is started
- do not start reading in case is not in limited buffer size
- do not start reading in case is a previous reading returns
a less data than read buffer size or are not in the hardware
flow control mode
Tested on Windows 8 with virtual com0com serial ports using Qt5 and then
Qt4.

In case of unsuccessful initialization of a device at the opening, a

WinCE implementation was mixed a common code with the Win32
implementation that caused some problems with maintenance.
More correct decision is moving a common code which was used
in *win.cpp into *wince.cpp module without modifications.
Now the Win32 and the WinCE implementation are independent
from each other.
Tested build with Qt5 on "win32-msvc2012" and then with Qt4
on "wincewm50pocket-msvc2008" configurations.
