On some linux systems /var/lock is not writable by users which are not
root and not in the uucp or dialout group.
If the root user acquires a lock and you are trying to access the same
port with a non-root user it will not check for the lock but creates a
new lock file in /tmp instead.
This change checks in readable directories for lock files.

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.

The method QSP::clear() can stall reading in case of following
situations:
- at the moment when PurgeComm abort of previously started
asynchronous reading operation
- when a serial port is in hardware flow control mode
- when a serial port has a limited read buffer size
Therefore is necessary restart of asynchronous reading to enable
of the read sequence.

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.

1. The writeStarted flag shall be reset to false after bytesWritten() signal
is emitted, but not before it.
2. In case of start of writing from the startAsyncWriteTimer it is necessary
to call the startAsyncWrite() method but not the completeAsyncWrite() method.
It give guarantees to exclude of race condition to multiple call of the
WriteFile twice until the write operation is not completed.
For example, a race condition is watched in case of writing data from the
slots which are connected to the bytesWritten() signal from a device; or to
the timeout() signal from a timer with zero interval. To checking of these
scenarios are added additional autotests.
Tested on Windows 8 with the on-board and USB serial ports, using Qt5.

Previous commit 76f293bfb0fd7bab391f96ac822eacc40e4c5176 with adding of
this test to the benchmarks were hasty.
After all it makes sense to place it to auto tests to have opportunity to
run with others together.
Besides, this test is renamed since it is not a loopback, it is an I/O
test with the synchronous approach.

Using of the QString::fromWCharArray() we didn't pass length of a string,
hoping that all WCHAR strings are terminated by the null-character.
But it can lead to the wrong results if the initial WCHAR string has no
null character. Therefore it is reasonable to pass length of a string to
exclude an error.
Besides, to do not break of the algorithm of string comparison it is
necessary to return not null-terminated strings. Also now there is no need
to initialize of some allocated arrays by zero values.

Good reason to check of data correctness at transferring and receiving.
In this test are used two serial ports, connected in a null-modem mode:
http://en.wikipedia.org/wiki/Null_modem .
The sender port transfers data to the receiver port. After data are
received is carried out check of equivalence of the transferred and
received data.
Before run of testing it is necessary to set two variable environments
QTEST_SERIALPORT_SENDER and QTEST_SERIALPORT_RECEIVER to specify names
of used serial ports.
This test can reveal errors related with the internal data processing
and also errors of synchronous I/O inside of QSerialPort.
This test is placed in separate "benchmarks" category not to mix-up
with "manual" and "auto" categories, because this test is closer to
"benchmarks" by own functionality.
Tested on Windows 7/8 with the virtual com0com serial ports, using

The current implementation of the qserialportinfo_mac.cpp module is a
little confused and complicated.
It is reasonable to re-write it using some ready wrappers of CFTypeRef,
CFStringRef and others objects from the private qcore_mac_p.h file.
Thus, it will allow to bypass of manual releasing of the allocated
resources (using the RAII idiom where it is possible), and also to
simplify a code.

Thus, all code of the serialportinfo_unix.cpp module, which not related
with the OS X, is shielded by a macro. It adds an excessive garbage for
readability in this module and also some confusion in the *.pri file.
It makes sense to make implementation of the serialportinfo_mac.cpp
module completely independent, that will simplify maintaining of source
code.
Besides are added tests which can reveal declared but not implemented
methods in building, and also to check a correctness of default values
at running.
Tested build on OS X 10.8.4 with Qt4, an then on Android with Qt5.

The slots _q_completeXX() returns empty values, therefore the
waitForXX() methods continue to work even if occurs an error
from the I/O completion.
Is reasonable allow to return of boolean values for the I/O
completion slots.
Besides, it allows avoiding indirect detection of an error,
comparing of the sizes of I/O buffers before and after the
operation completion. Though, for the waitForReadyRead(),
for this purpose it is necessary to add additional
modifications in a following patches.
Tested on Windows 7/8 with the virtual com0com ports using
Qt4 and then Qt5. Testing was made using of autotests
and examples.

Each q_completeXXX() slot does call of GetOverlappedResult()
and differently interprets an error depending on the type of
I/O operation (read, write or communication).
It is more reasonable to make it in the separate method
handleOverlappedResult() which returns the number of the
transferred bytes or -1 in case of error.
Besides, this method accepts the additional integer parameter
which expresses type of overlapped operation using the
existing QSerialPort::Direction enumeration. The type of the
communication operation has not separate value, so is used
zero value for it.
Tested build on Windows 7/8 using Qt4 and then Qt5.

When in readNotification() or completeAsyncWrite() an error
is emitted and the loop is not exited, this error signal
will flood the eventloop.

The standard USB CDC driver (usbser.sys) does not add information of
serial number to the device instance identifier of the child devices
(serial ports), so our algorithm returns an empty string.
But information about a serial number is stored in the device identifier
of the parental node. Thus, it is necessary to get this parent
identifier, using these recommendations from MSDN:
http://msdn.microsoft.com/en-us/library/windows/hardware/ff549417%28v=vs.85%29.aspx
For this purpose is used the set of new functions from the
"Configuration Manager Functions" family.
Therefore it was necessary:
* Rewrite the deviceInstanceIdentifier() function.
Now this function accepts one DEVINST parameter and returns the
corresponding device instance identifier string.
* Add the new parentDeviceInstanceNumber() function.
This function accepts a DEVINST of the child device and returns a
DEVINST of the parent device.
Thus, the new algorithm tries to extract a serial number from the
current (child) device and in case it is empty, try to extract from
the parent.
Tested on Windows 7/8 with the Segger JLink device (provides the CDC
serial port) using Qt4 (MSVC2010) and then Qt5 (MSVC2012, MinGW).
Also are checked other devices for possible regressions:
* on-board serial port
* com0com virtual serial port
* USB FTDI serial port
no regressions found.

To the ResourceError handling we generally relied on triggering of the
_q_completeAsyncCommunication(), in case of ejection of an USB device
from a host. But it worked with not all USB devices (for example it did
not work with the ZTE modems). Even when this worked (for example with
the PL2303 devices), then we got the non informative "Unknown error" of
the ResourceError string representation.
It is more reasonable not to do any custom checks of an event mask when
triggered of the _q_completeAsyncCommunication() method. We need allow
to detect an errors with means of the
ReadFile/GetOverlappedResult/WaitCommEvent syscalls on an invalid device
handle.
An important note is that returns the different error codes for a
different types of devices.
For example:
* For the USB ZTE and the Samsung Android USB modem returns the
ERROR_ACCESS_DENIED error code.
* For the FTDI and the Samsung Android Diagnostic Serial Port returns
the ERROR_OPERATION_ABORTED error code.
* For the USB PL2303 device returns the ERROR_BAD_COMMAND error code.
Thus, there is no universal solution of this issue. Each vendor of the
driver implements it own way. Therefore for each new type of the device
it is necessary to add processing its error code, if we have no it yet.
Tested on Windows 7/8 with the USB ZTE and the Android modems, with the
USB PL2303 and the FTDI devices and with the Android diagnostic serial
port using Qt4 and then Qt5, no regressions found.

* It is necessary to ignore the NoError error code.
* In case of error from GetOverlappedResult() it is necessary to stop
the I/O operation by a immediate return from the function, because I/O
processing does not make sense. This is consistent behavior similar to
starting I/O operations.
* All errors from the read completion should be interpreted as ReadError.
Exception is only the critical ResourceError error which it is necessary
to leave without changes. This is also consistent behavior similar to
starting I/O operations.
* The write completion error handling should be similar to the read
completion handling.
* For the communication completion we have no specific error codes.
Therefore error handling shall be without modification of their error
code.
Also were made small cosmetic fixes to the related start I/O methods.
Tested on Windows 7/8 with the on-board, the PL2303 and the virtual
com0com serial ports using Qt4 and then Qt5. Testing are made by means
of examples of library and also by means of auto tests, no regressions
found.

So far only the module was excluded, but not the examples.
Adopt to a style which has been approved for other modules as well
by using requires.
