When timezone support for QDateTime was added, we decided it was a good
idea to delay creating the QTimeZone object and checking that the time
is valid in that timezone (including for local time) until the user
requested that information. Unfortunately, QExplicitlySharedDataPointer
returns a non-const T* in operator->(), which meant we were accidentally
modifying the d pointer's contents in const methods, which in turn means
those const methods were not thread-safe when operating on the same
object.
This commit changes the d pointer to QSharedDataPointer, which is safer
in this regard and pointed out where the issues with constness were
located. Since we can't lazily calculate QTimeZone anymore, we need to
do it whenever the date, time or offset changes.

The new mode, ParseAsPositionalArguments, allows to interpret
"application argument --opt" as having two positional arguments,
"argument" and "--opt".
This mode is useful for executables that aim to launch other executables
(e.g. wrappers, debugging tools, etc.) or who support internal commands
followed by options for the command. "argument" is the name of the command,
and all options occurring after it can be collected and parsed by another
command line parser, possibly in another executable.
[ChangeLog][QtCore][QCommandLineParser] Add parsing mode for options
after arguments, to allow treating them as more arguments.

The c2m() function which converts a const_iterator into an iterator
is a broken concept for an implicitly shared container such as
QVector, because the act of calling begin() as the starting
point already detaches and invalidates the c2m argument.
This could be fixed in c2m, but the bug wasn't even in c2m,
but in removeAll(), which called end() before c2m, so the c2m
argument was already invalidated when entering c2m.
The solution is to store the positions as indices instead of
iterators before calling the first detaching function.

The Movable type, surprisingly, was as large as sizeof(void*), so on
32-bit platforms, we were not testing the QList memory layout where
items are placed directly into the void*-slots, but are too small,
leaving gaps.
Fixed by making sure that Movable is smaller than void* and adding
a variant of Movable, Optimal, that is guaranteed to be the same
size as void*, and replacing the int tests with tests of Optimal.
Had to demote the State variable to uchar, since MSVC will apparently
not make a collection of bit-fields smaller than the largest type used
in any of the consituent bitfields, so State s : 8 wouldn't work.

qHashRange() takes an (input iterator) range and hashes each element, combining

http://stackoverflow.com/questions/4948780/magic-number-in-boosthash-combine
qHashRangeCommutative() does the same but with a cummutative combiner (unsigned
addition) to create hash values that are order-independent, e.g. for hashed
containers. The obvious combiner, XOR, is a bad one because it eliminates
duplicate elements. Signed addition cannot be used, since signed overflow
leads to undefined behavior.

Of the const overloads that return a QString or a QByteArray, this is
