An object that throws in its constructor cannot be reentered. This
violates both C++11 and C++98. It's also a regression from MSVC 2013.
The unit test is renamed to indicate what it really does, as opposed to
a misleading name that was probably a "thinko" on my part.

OS X has an unreasonably low default for the maximum number of open
file descriptors (256). The unit test creates about 200 threads and each
thread in Qt creates at least two file descriptors (pipe), so the test
cannot execute.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

The problem was that the HolderBase destructor was getting called after
the contained type's constructor threw an exception, as is required by
RAII semantics (the base was fully initialized, so it had to be
destroyed). That was required because we want to return a non-null
pointer from operator() during destruction and return null after
destruction, to keep compatibility with Qt 4.
The solution is to only set the guard to Destroyed only if it is already
at value Initialized. This way, if the HolderBase destructor is run as
part of the stack unwinding, it knows that the construction did not
complete.

Unlike the previous implementation, this implementation is locked:
only one initialisation is ever run at the same time. It is
exception-safe, meaning that a throwing constructor will restart the
process.
Also, start using the thread-safe behaviour that GCC has offered for a
long time and C++11 requires.
