We don't know which versions these blacklistings actually apply on
unless we actually get macOS 10.14 and 10.15 into the CI and running
tests, so let's start with that, and then granularize the blacklists
after that.

Using wrappers for these macros is problematic when for example passing the
-frewrite-includes flag to preprocess sources before shipping off to distcc
or Icecream. It will also start producing warnings when compilers implement
http://eel.is/c++draft/cpp.cond#7.sentence-2. See for example
https://reviews.llvm.org/D49091
Both https://clang.llvm.org/docs/LanguageExtensions.html and the SD-6 document at
https://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations
recommend defining '__has_foo(x) 0' as a fallback for compilers without the
macros, so that's what we go for.

Only allow implicit conversions when the types involved are compatible.
That means, only allow construction and copy assignment when the type
X* is convertible to type T*. This is done using SFINAE and the
std::is_convertible type trait, which makes the previous
QSHAREDPOINTER_VERIFY_AUTO_CAST obsolete.
This patch fixes compilation when a function is overloaded with
Q{Shared,Weak}Pointer of different, incompatible types. Previously, this
resulted in a compilation error due to an ambiguous overload.

Both the spline curves and (most of) the predefines curves are defined
as having start value 0.0 and end value 1.0. The spline and In/OutBack
functions would sometimes not produce that result precisely, so code
could not reliably depend on expressions like (easedValue < 1.0)
becoming false. Fix by explicitly handling endpoints.

The code made two incorrect assumptions: that the strings used are "AM"
or "PM", or would be translated. Instead, the locale provides the
correct strings, and there is no need to translate. However, in order
not to break existing translations, we give those preference.
And that the AM/PM string is not longer than 4 characters, while in
e.g Spanish/Columbia locale the strings are "A. M." and "P. M.", ie 5
characters long. Also, the use of qMin in a function that is asked to
provide the maximum section length is wrong.
[ChangeLog][QWidgets][QDateTimeEdit] Use the information provided by
the locale to determine the AM/PM strings, unless they are already
translated.

... spotted with the brand-new checks for that in QCharRef.
The rx[i] == ~~~ check is clearly wrong, as rx is the regexp
we're building and `i` was not supposed to index into it.
The intended meaning was wc[i] == ~~~, testing if we were seeing
the closing bracket of a character set. We need to check for
that immediately for dealing with the special syntax of []...] where
the ] belongs to the character set (it can't be the closing one
as character sets cannot be empty).
Fix and add a regression test. Bonus: this code was almost
unchanged since 2009.

NoDefaultConstructorRef1 was taking a reference of the input, which
meant in the first test it would get a reference to the temporary
created by the 1 literal. A temporary that would be out of scope by
the time we check its value.
Instead add a test with unique_ptr to test we can pass movable
temporaries.

We'll be adding calendar code here as well, and tools/ was getting
rather crowded, so it looks like time to move out a reasonably
coherent sub-bundle of it all.

We have a problem. Our types don't play well with the std unordered
containers, because they do not specialize std::hash. We therefore
force our users to come up with an implementation, hindering
interoperability, since any two developers are unlikely to come up
with compatible implementations. So combining libraries written by
different developers will result in ODR violations.
Now that we depend on C++11, and thus the presence of std::hash, we
still face the problem that the standard does not provide us with a
means to compose new hash functions out of old ones. In particular, we
cannot, yet, depend on C++17's std::hash<std::string_view> to
implement std::hash<QByteArray>, say. There's also no std::hash for
std::tuple, which would allow easy composition by using std::tie().
So piggy-back on the work we have done over the years on qHash()
functions, and implement the std::hash specializations for Qt types
using the existing qHash() functions, with a twist: The standard
allows implementations to provide means against predictable hash
values. Qt has this, too, but the seed is managed by the container and
passed to the qHash() function as a separate argument. The standard
does not have this explicit seed, so any protection must be implicit
in the normal use of std::hash.
To reap whatever protection that std library has on offer, if any, we
calculate a seed value by hashing int(0). This will be subject to
constant folding if there's no actual seed, but will produce a value
dependent on the seed if there is one.
Add some tests.
A question that remains is how to document the specialization. Can we
have a \stdhashable QDoc macro that does everything for us?
