QUtf32::convertToUnicode() was forgetting to set headerdone when it
dealt with the header (for contrast, Utf16::convertToUnicode() does).

Use QStringIterator rather than indexed loops. This fixes handling of
non-BMP code points (which may be lower or uppercase, see the test).
Change also the semantics of the functions, adopting Unicode §3.13
definitions: a string is lowercase/uppercase if it's equal to its
own toLower/toUpper folding.
As a side effect, empty strings are now correctly reported to be
lowercase AND uppercase.
[ChangeLog][Important Behavior Changes] The semantics of
QString::isLower() and QString::isUpper() have been changed to match the
Unicode specification. Now lowercase (resp. uppercase) strings are
allowed to contain any character; a string is considered lowercase
(resp. uppercase) if it's equal to its own toLower() (resp. toUpper())
folding. Previously, a non-letter character would make the string not
lowercase nor uppercase, and the mere presence of an uppercase (resp.
lowercase) letter would make isLower() (resp. isUpper()) return false,
even if the letter wouldn't change under case folding. As a
consequence, now empty strings are lowercase and uppercase.
[ChangeLog][QtCore][QString] Fixed a number of bugs of
QString::isLower() and QString::isUpper(). Empty strings are now
correctly reported to be lowercase (resp. uppercase), and strings
containing code points outside the BMP are now correctly handled.
Note that the behavior of these functions has also been changed.

QString(View)s can be built or manipulated in ways that make them
contain/refer to improperly encoded UTF-16 data. Problem is,
we don't have public APIs to check whether a string contains
valid UTF-16. This knowledge is precious if the string is to be fed in
algorithms, regular expressions, etc. that expect validated input
(e.g. QRegularExpression can be faster if it can assume valid UTF-16,
otherwise it has to employ extra checks).
Add a function that does the validation.
[ChangeLog][QtCore][QStringView] Added QStringView::isValidUtf16.
[ChangeLog][QtCore][QString] Added QString::isValidUtf16.

The qmake config for tst_QString tried to impose QT_NO_CAST_TO_ASCII
on it, but the source file explicitly #undef-s this symbol and its
friends. Leave the define commented out in the .pro so that a comment
can explain why it's no good.

Test QT_CONFIG(icu) in the code instead of testing qtConfig(icu) in
the profile and setting an extra define just to shadow what's already
defined. Also remove the matching define from qcollator.pro, whose
test code didn't use it.
Noticed while reviewing the conversions to CMake.

QString::fromAscii() is deprecated since 5.0 but still tested.
So suppress deprecations for its code.

Now that all our supported compilers know char16_t, we no longer need
QStringViewLiteral, whose only purpose in life was to turn u"" into
L"" for MSVC < 2015.
