When the hostname is empty then it is assumed that the lock file is from
the same host as the one running the application.

To cover the situation that the process ID got reused, the current
process name is compared to the name of the process that corresponds
to the process ID from the lock file.
If the process names differ, the lock file is considered stale.
[ChangeLog][QtCore][QLockFile] Detection of stale lock files got more
robust and takes the name of the process that belongs to the stored
PID into account.

the stale file detection logic from triggering.

a system folder guarded with checks for elevated processes

Unlike qAppName, it doesn't require a QCoreApplication instance,
making QLockFile usable in destructors of global statics.
This also uses the value passed to setApplicationName if called
rather than always argv[0].

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

A "sharing violation" happens when trying to delete the lock file and another
thread/process is reading it at that very moment. Detect the error and try again,
up to 10000 times - to avoid an infinite loop if QFile::remove fails for another
reason such as a sudden change of permissions preventing us from deleting our
own lock file.
On Unix the deletion can't fail because of readers, but it doesn't hurt
to check the return value there too, to catch other reasons for failures
such as a sudden permission change.

While some functionality is not available for winphone
(QFileSystemEngine::tempPath), some functionality can
be fully supported. Other cases like checking for stale
processes which is needed by QLockFile cannot be covered
that easily as obtaining information about other processes
is limited due to sandboxing.

Locking between processes, implemented with open(O_EXCL) on Unix
and CreateFile(CREATE_NEW) on Windows.
Supports detecting stale lock files and deleting them.
Advisory locking is used to prevent deletion of files that are still in use.
