Irrelevant once we get to C++11 (so we can revert this in 5.7), but
division's rounding direction is implementation defined when either
operand is negative [0]. The prior code assumed C++11's truncation
(a.k.a. round towards zero), but rounding may be downwards instead.

There are three deprecated language codes that Java still uses for the
locale so we need to account for these inside QLocale by mapping them to
the right language.

When QDateTime::addDate() and friends sanitize their end-state, they
were using the DST status of their start-state (if known) to control
it. This lead to misguided results and, in particular, inconsistent
results given that a raw-constructed QDateTime comes into being
ignorant of its DST, while a .toLocalTime() one knows its DST.
Furthermore, the code to do this was triplicated, tricky and poorly
explained. So pull it out into a local static function and explain
what it's doing, and why, more clearly and only once.

This partially reverts commit e486d69133178ccce7c75cf48201ab28efb20e44.
It broke too many users, even though all of them deserved to be broken.
The new functionality will be provided by differently-named functions,
where possible (problem: equality operators).
I did not revert the fix for the off-by-one error in
tst_qtextdocumentfragment.cpp.
I also didn't revert the change in the inequality relational operators,
since for all strings s1, s2 and s2' where s2' is s2 truncated at the
first NUL, s1 < s2 ⟺ s1 < s2' (since NUL < c for any c != 0), and,
trivially, for ≤, >, ≥, too. This does not hold for = and ≠, of course,
since "foo\0bar" ≠ "foo".

On some Debian distros, the TZ environment variable can be set to
":/etc/localtime", which libc defines as "default value". If this is
set, the current QTimeZone parsing code will return "/etc/localtime"
as the system timezone id, which is clearly wrong.
So in that case, just unset the ianaId variable and let the other
blocks look for the timezone.

This reverts commit 5b62a5e7aabcc818408f2fe28b9760082f474def.
This commit is reverted due to two reasons:
1) It was written incorrectly and does not work as is. The
ifdefs should be ifndefs. In its current state, it does
the exact opposite of what it is supposed to be doing.
2) There is another environment access inside qsimd.cpp
(which checks QT_NO_CPU_FEATURE). This access causes the
app to hang.
All in all that approach is not sustainable as we might get
bitten by environment access again and again. Instead we should
use another environment container or use a recursive mutex for
WinRT and Windows CE.

Qt uses QHash as the container for faking environment variables on
Windows Runtime and CE. Environment variable manipulation functions are
protected by mutex. Accessing the QT_HASH_SEED environment variable
inside QHash can lead to situation where qputenv() call leads to
qgetenv() call and that leads to a deadlock. Since the application
environment is faked anyway, drop support for QT_HASH_SEED and ifdef
that functionality out on those platforms. Documentation is updated
to reflect changes.

It's used from a different TU, too, so we can't rely on the
compiler to inspect it to draw this conclusion itself.
This function has technically not a wide contract, because
the output buffer needs to be large enough to hold the result.
However, this precondition cannot be checked from within the
function, therefore no assertion can ever be added and the
nothrow marker becomes acceptable (even desireable).

Now all Qt sequential containers consistently provide reverse iterators.
The associative ones, by way of not returning std::pair from op*, can't
just use std::reverse_iterator. They would miss .key() and .value() methods.
So that has to wait for 5.7.
The reverse versions of the new key_iterators can also just use
std::reverse_iterator, but I'm afraid that after bikeshedding over
keyRBegin() vs. rKeyBegin() vs. reverseKeyBegin() vs. rkbegin()
vs. krbegin() (<-- of course, what else?), it would anyway be too
late for 5.6, so defer, too.
