In the spirit of std::thread, which takes a function to call and its
parameters, and runs it in a new thread. Since the user might want to
connect to signals, move QObjects into the new thread, etc., the new
thread is not immediately started.
Although technically all of this _should_ be implementable in pure
C++11, there is nothing in the Standard to help us not reinvent all the
plumbing: packing the decay'd parameters, storing them, invoking the
function over the parameters (honoring INVOKE/std::invoke semantics).
std::function does not do the job, as it's copiable and therefore does
not support move-only functors; std::bind does not have INVOKE
semantics.
I certainly do not want to reimplement all the required facilities
inside of Qt. Therefore, the full blown implementation requires C++17
(std::invoke).
In order to make this useful also in pre-C++17, there are two additional
implementations (C++11 and C++14) that support just a callable, without
any arguments passed to it. The C++11 implementation makes use of a
class to store and call the callable (even move-only ones); basically,
it's what a closure type for a C++14 lambda would look like.
An alternative implementation could've used some of the existing
facilities inside QObject::connect implementation that store a functor
(for the connect() overload connecting to free functions), namely:
the QtPrivate::QFunctorSlotObject class. However:
* QFunctorSlotObject does not support move-only callables (see
QTBUG-60339);
* QFunctorSlotObject itself is not a callable (apparently by design),
and requires to be wrapped in a lambda that calls call() on it;
* the moment QTBUG-60339 is solved, we'd need the same handwritten
closure to keep QFunctorSlotObject working with move-only callabes.
So: just use the handwritten one.
The C++14 implementation is a simplified version of the C++11 one,
actually using a generalized lambda capture (corresponding to the
handwritten C++11 closure type).
All three implementations use std::async (with a deferred launch policy,
a nice use case for it!) under the hood. It's certainly an overkill for
our use case, as we don't need the std::future, but at least std::async
does all the plumbing for us.

As for the formatting code, de-duplicate the parsing code by only
parsing char*s, converting QChars to Latin-1 first in a small buffer.
The QUuid(const char*) ctor performed no length checking, relying
instead on the checks performed within _q_uuidFromHex(), which
includes an implicit check for premature end (because NUL is not
a valid token for the parser).
The (QString) and (QByteArray) ctors did perform length checking.
To the extent possible, this is removed, since it is handled by
_q_uuidFromHex(). Failure cases need not be optimized. Only the
QLatin1String overload needs to do some checking, because views in
general are not NUL-terminated. The QStringView overload can just
append a NUL when it converts to Latin-1.
The only check I added to _q_uuidFromHex() is that for src ==
nullptr. It would otherwise be duplicated in several callers.
