Dependies for class QLockFile make it impossible easy backport this class to

Browse Source 
Qt 5.0.0. I decided don't do this. And just disable using the class if
Qt version < Qt 5.1. It will open some issues, but for Unit testing this reason
not important.

Helper class that automates refernce counting for CFtypes.
After constructing the QCFType object, it can be copied like a
value-based type.
Note that you must own the object you are wrapping.
This is typically the case if you get the object from a Core
Foundation function with the word "Create" or "Copy" in it. If
you got the object from a "Get" function, either retain it or use
constructFromGet(). One exception to this rule is the
HIThemeGet*Shape functions, which in reality are "Copy" functions.

/*! \class QFSFileEngine
\inmodule QtCore
\brief The QFSFileEngine class implements Qt's default file engine.
\since 4.1
\internal
This class is part of the file engine framework in Qt. If you only want to
access files or directories, use QFile, QFileInfo or QDir instead.
QFSFileEngine is the default file engine for accessing regular files. It
is provided for convenience; by subclassing this class, you can alter its
behavior slightly, without having to write a complete QAbstractFileEngine
subclass. To install your custom file engine, you must also subclass
QAbstractFileEngineHandler and create an instance of your handler.
It can also be useful to create a QFSFileEngine object directly if you
need to use the local file system inside QAbstractFileEngine::create(), in
order to avoid recursion (as higher-level classes tend to call
QAbstractFileEngine::create()).

/*!
\class QLockFile
\inmodule QtCore
\brief The QLockFile class provides locking between processes using a file.
\since 5.1
A lock file can be used to prevent multiple processes from accessing concurrently
the same resource. For instance, a configuration file on disk, or a socket, a port,
a region of shared memory...
Serialization is only guaranteed if all processes that access the shared resource
use QLockFile, with the same file path.
QLockFile supports two use cases:
to protect a resource for a short-term operation (e.g. verifying if a configuration
file has changed before saving new settings), and for long-lived protection of a
resource (e.g. a document opened by a user in an editor) for an indefinite amount of time.
When protecting for a short-term operation, it is acceptable to call lock() and wait
until any running operation finishes.
When protecting a resource over a long time, however, the application should always
call setStaleLockTime(0) and then tryLock() with a short timeout, in order to
warn the user that the resource is locked.
If the process holding the lock crashes, the lock file stays on disk and can prevent
any other process from accessing the shared resource, ever. For this reason, QLockFile
tries to detect such a "stale" lock file, based on the process ID written into the file,
and (in case that process ID got reused meanwhile), on the last modification time of
the lock file (30s by default, for the use case of a short-lived operation).
If the lock file is found to be stale, it will be deleted.
For the use case of protecting a resource over a long time, you should therefore call
setStaleLockTime(0), and when tryLock() returns LockFailedError, inform the user
that the document is locked, possibly using getLockInfo() for more details.
*/
/*!
\enum QLockFile::LockError
This enum describes the result of the last call to lock() or tryLock().
\value NoError The lock was acquired successfully.
\value LockFailedError The lock could not be acquired because another process holds it.
\value PermissionError The lock file could not be created, for lack of permissions
in the parent directory.
\value UnknownError Another error happened, for instance a full partition
prevented writing out the lock file.

Sets \a staleLockTime to be the time in milliseconds after which
a lock file is considered stale.
The default value is 30000, i.e. 30 seconds.
If your application typically keeps the file locked for more than 30 seconds
(for instance while saving megabytes of data for 2 minutes), you should set
a bigger value using setStaleLockTime().
The value of \a staleLockTime is used by lock() and tryLock() in order
to determine when an existing lock file is considered stale, i.e. left over
by a crashed process. This is useful for the case where the PID got reused
meanwhile, so the only way to detect a stale lock file is by the fact that
it has been around for a long time.

available.
Note: Passing a negative number as the \a timeout is equivalent to
calling lock(), i.e. this function will wait forever until the lock
file can be locked if \a timeout is negative.
If the lock was obtained, it must be released with unlock()
before another process (or thread) can successfully lock it.
Calling this function multiple times on the same lock from the same
thread without unlocking first is not allowed, this function will
\e always return false when attempting to lock the file recursively.

Retrieves information about the current owner of the lock file.
If tryLock() returns \c false, and error() returns LockFailedError,
this function can be called to find out more information about the existing
lock file:
\list
\li the PID of the application (returned in \a pid)
\li the \a hostname it's running on (useful in case of networked filesystems),
\li the name of the application which created it (returned in \a appname),
\endlist
Note that tryLock() automatically deleted the file if there is no
running application with this PID, so LockFailedError can only happen if there is
an application with this PID (it could be unrelated though).
This can be used to inform users about the existing lock file and give them
the choice to delete it. After removing the file using removeStaleLockFile(),
the application can call tryLock() again.
This function returns \c true if the information could be successfully retrieved, false
if the lock file doesn't exist or doesn't contain the expected data.
This can happen if the lock file was deleted between the time where tryLock() failed
and the call to this function. Simply call tryLock() again if this happens.

\class QMutexPool
\inmodule QtCore
\brief The QMutexPool class provides a pool of QMutex objects.
\internal
\ingroup thread
QMutexPool is a convenience class that provides access to a fixed
number of QMutex objects.
Typical use of a QMutexPool is in situations where it is not
possible or feasible to use one QMutex for every protected object.
The mutex pool will return a mutex based on the address of the
object that needs protection.
For example, consider this simple class:
\snippet code/src_corelib_thread_qmutexpool.cpp 0
Adding a QMutex member to the Number class does not make sense,
because it is so small. However, in order to ensure that access to
each Number is protected, you need to use a mutex. In this case, a
QMutexPool would be ideal.
Code to calculate the square of a number would then look something
like this:
\snippet code/src_corelib_thread_qmutexpool.cpp 1
This function will safely calculate the square of a number, since
it uses a mutex from a QMutexPool. The mutex is locked and
unlocked automatically by the QMutexLocker class. See the
QMutexLocker documentation for more details.
*/
/*!
Constructs a QMutexPool, reserving space for \a size QMutexes. All
mutexes in the pool are created with \a recursionMode. By default,
all mutexes are non-recursive.
The QMutexes are created when needed, and deleted when the
