The implementation was inconsistent with QString::right(),
and did not return the N rightmost characters but actually did
the same as QString::mid(N) (returning the rightmost size - N
characters.)
Since this function is fairly recent (Qt 5.2), is documented to
behave the same as QString::right(), and since these APIs are
meant to be interchangeable, this needs to be fixed, even though
it changes behavior.
[ChangeLog][Important Behavior Changes] Changed QStringRef::right()
to be consistent with QString::right(). The function now returns
the N right-most characters, like the documentation already claimed.

The result of qstrtoull() was unconditionally truncated to an int,
resulting in wrong values being appended to the segments vector
when the numerical segment value was above INT_MAX.
Prevent this by first checking the return value of qstrtoull
as a qulonglong for values larger than INT_MAX and stopping
processing in that case. That means that segments that
numerically overflow an int are now considered part of the
suffix.
Also added tests for the case where a segment value is larger
than ULLONG_MAX. That was already working correctly.

we skip in our CI system. This adds a blacklisting
mechanism that allows blacklisting individual test

QTestlib will search for a file called BLACKLIST in the test

Do a check first if we need to transform before doing the transform.
This means we won't detach when transforming data that is already
correct.
And instead of using QChar, use our own hand-rolled table. In a proper
LTO build, the QChar calls would be resolved to a lookup of the Unicode
data, but not many people do LTO builds, Therefore, this means a great
speed-up is achieved by simply avoiding the function call. The extra
gain in performance comes from the simpler translation table instead of
the more complex full-Unicode data.
Also as a consequence, this changes the handling of two characters in
Latin 1: 'ß' should be uppercased to "SS" but we won't do it, and 'ÿ'
can't be uppercased in Latin 1 ('Ÿ' is outside the range).
Benchmarking is included. Comparing the Qt 5.4 algorithm to the new code
is almost 20x faster. Other alternatives are included in the benchmark
and are all faster than the current code, though slower than the new
one. While all of them could compress the tables to be smaller or shared
between uppercasing and lowercasing, they would also expand to more code
(though probably less than the extra bytes required in the full
translation table). In the trade-off, I decided to go with simplicity
and most efficient code.

- make the constructor a template member
=> it compiles if the parameter is a QByteArray, but not a const

- inheriting constructors

The goal of this commit to make the code in the test work:
QCommandLineParser parser;
parser.addOptions({
{ "a", "The A option." },
{ { "v", "verbose" }, "The verbose option." },
{ { "i", "infile" }, "The input file.", "value" },
});
For this, QCommandLineParser needs a version of addOption that can
take a list of options. That's what addOptions() is for.
More importantly, the QCommandLineOption ctors mustn't be explicit.
OTOH, any implicit conversion from QString or QStringList to
QCommandLineOption is also undesirable.
To solve this dilemma, add new QCommandLineOption ctors that just
take one argument and are explicit, and make the existing ctors
implicit. In order to avoid ambiguities, remove the default values
of their resp. 2nd arguments. The new ctors are by intention not
\since 5.4, as they are completely transparent to the user.
Et voila, even better than getopt_long(3).
