There's no reason to restrict the LHS and the RHS to the same type
like it was done before. That just leads to lots of casting. or use
of QVERIFY(. == .) instead of QCOMPARE, with all the disadvantages
like no printing of the LHS and RHS values.
The rationale given in the documentation for this behavior is
incorrect. Ensuring that RHS and LHS have the same type by no means
ensures that no implicit conversions take place when calling
operator==. Proof:
QCOMPARE(QLatin1Char('a'), QLatin1Char('a'));
// instantiates
qCompare<QLatin1Char, QLatin1Char>
// but calls
operator==(QChar, QChar)
If the intent is to disable implicit conversions of the argument
types, then some serious metaprogramming magic would be needed, along
the following lines:
1. find out which op== overload is actually chosen
2. find that overload's RHS parameter type, assert it's the same as
(possibly cv-qualified) T1.
3. ditto for the LHS parameter type and T2
This is not attempted here.
Fix the inconvenience this restriction caused by simply allowing
two types.
This cannot break existing code, since we didn't actually change
anything in the qCompare() overload set. All we do is implement the
existing qCompare<T1, T2>() overload.
[ChangeLog][QtTest] QCOMPARE can now be used for mixed-type
comparisons.

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.
While touching the internal functions, port to passing and returning
by value.
