8acec4dbe6 Long live QUtf8::convertFromLatin1()!
With the introduction of QAnyStringView, overloading based on UTF-8
and Latin-1 is becoming more common. Often, the two overloads can
share the processing backend, because we're only interested in the
US-ASCII subset of each.

But if they can't, we need a faster way to convert L1 into UTF-8 than
going via UTF-16. This is where the new private API comes in.

Eventually, we should have the converse operation, too, to complete
the set of direct conversions between the possible three
QAnyStringView encodings L1/U8/U16, but this direction is easier to
code (there are no error cases) and more immediately useful, so
provide L1->U8 alone for now.

122270d6be Long live the ICU-based QStringConverter interface!
This adds support for additional codecs to QStringConverter when ICU is
available.

We store the converter in the state (d[0]), and its canonical name in
d[1]. We need the name there, as in the clear function we close the
UConverter, and set the pointer to null. Consequently, the actual
conversion functions might need to re-open the converter again. The
advantage of this approach is that clear is used in the destructor of
State, and with this approach we properly clean up the state.
There is however a disadvantage: The clear function was so far also used
for resetting the state when QStringConverter::resetState . Discarding
the whole Uconverter for that is however rather costly. For that reason
we modify resetState to call a new function, State::reset. For existing
converters, it behaves the same as clear; for the ICU based converter,
we call the more efficient ucnv_reset. Code compiled against Qt 6.4 can
benefit from this more efficient version; code compiled against older Qt
versions will continue to work, as the conversion functions can just
recretate the converter from the name.
We can distinguish between ICU and non-ICU converters by checking if the
UsesIcu flag is set.

QStringConverter::name is changed to return the name stored in d[1]. The
interface of the ICU converter has a dummy name, so code using the old
name function from QT < 6.4 still returns something, namely a message
asking the user to recompile.
The function is moved out of line, as we need to check for the private
ICU feature, and want to avoid having that check in the public header.

As the QStringConverter ctor taking a name now can allocate memory, it
can no longer be noexcept. Removing the noexceptness is safe, as it was
only added after Qt 6.3.

Note that we cannot extend the API consuming or returning Encoding, as
we use Encoding values to index into an array of converter interfaces in
inline API.

Further API to support getting an ICU converter for HTML will be added
in a future commit.

Currently, the code depending on ICU is enabled at compile time if ICU
is found. However, in the future it could be moved into a plugin to
avoid a hard dependency on ICU in Core.

[ChangeLog][Corelib][Text] QStringConverter and API using it now
supports more text codecs if Qt is compiled with ICU support.

9bad4be214 QStringConverter: use the QUtf8 codec when Windows is using UTF-8
The QLocal8Bit implementation assumes that there's at most one
continuation byte -- that is, that all codecs are either Single or
Double Byte Character Sets (SBCS or DBCS). It appears to be the case for
all Windows default codepages, except for CP_UTF8, which is an opt-in
anyway.

Instead of fixing our codec, let's just use the optimized UTF-8
implementation.

[ChangeLog][Windows] Fixed support for using Qt applications with UTF-8
as the system codepage or by enabling that in the application's
manifest.

1869615fc9 QChar: make construction from integral explicit
QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).

David provided the perfect example:

  if (str == 123) { ~~~ }

compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.

Add a macro to revert to the implicit constructors, for backwards
compatibility.

The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.

e81330d327 Add explicit encode()/decode() methods to QStringConverter
The functional style interface is nice, but does feel alien in some
contexts, so better also have explicit encode and decode methods.

57037145f5 Streamline the code in the conversion to and from utf8
Move pre/and post condition handling out of the main loop
to make that one as fast as possible.

Remove special handling of a corner case when the input length
is zero, where the utf8 decoder did something else than all
other decoders.

124d587bb9 Document the string converter classes
Document QStringConverter, QStringDecoder and QStringEncoder.

In addition, do some touches to the API, renaming one enum value,
add a flags argument to one constructor and make some members private.

Add a constructor, that allows constructing a string converter by
name. This is required in some cases and also makes it possible to
(in the future) extend the API to 3rd party encodings.

Also add a name() accessor.

cab0d57d1e Clean up the Flag handling in QStringConverter
IgnoreHeader was a rather badly defined enum, in addition the
utf8 and utf16 codecs where handling BOMs somewhat different
for stateless decoding.

Fix this by introducing explicit flags for writing a bom when
encoding and not skipping the initial bom when decoding.

Source compatibility for QTextCodec is done with a couple of
static constexpr variables.

f64a6bd638 Start work on a new API to replace QTextCodec
The new QStringEncoder and QStringDecoder classes
(with a common QStringConverter base class) are
there to replace QTextCodec in Qt 6.

It currently uses a trivial wrapper around the utf
encoding functionality.

Added some autotests, mostly copied from the text codec
tests.
