a111dd26b1 Document the indexing used in the Unicode tables
Make clear why we don't need to assert against out-of-bounda accesses
in the generated code, provided the code point is within its bound,
(Using one table's early entries as indices into later in the same
table at which to look up indices into another table made it a little
hard to work out what was going on, especially as nothing told me
about the early / late distinction. Record what I discovered, to save
the next person to stumble into this some confusion.)

e3e6d58cad Use %zd for size-type formatting in unicode table generator
Qt6 makes sizes qsizetype; and one of these was already sizeof()-sized.
While qsizetype might not be ssize_t, it's at least no bigger, so we
can safely use its format specifier, with a suitable cast.

3e1d03b1ea Port Q_STATIC_ASSERT(_X) to static_assert
There is no reason for keep using our macro now that we have C++17.
The macro itself is left in for the moment being, as well as its
detection logic, because it's needed for C code (not everything
supports C11 yet).  A few more cleanups will arrive in the next few
patches.

Note that this is a mere search/replace; some places were using
double braces to work around the presence of commas in a macro, no
attempt has been done to fix those.

tst_qglobal had just some minor changes to keep testing the macro.

19e7c0d2b5 QChar/QString: centralize case folding in qchar.cpp
There are (at least) two implementations of the low-level case-folding
algorithm, one of which (for QChar::toLower()) seems to be wrong (it
doesn't deal with special cases which expand to more than one code
point).

The algoithm hidden in QString and entangled with the QString
detaching code makes reusing the code much harder.

At the same time, the dependency of the algorithm on the unicode
tables makes exposing a non-allocating result type in the public API
hard. std::u16string would be an alternative if we can assure that all
implementations use SSO with at least four characters.

So, for the time being, leave this as internal API for use in an
upcoming QStringView::toLower() as well as case-insensitive hashing.

20cdf807b1 QChar: port low-level functions from uint/ushort to char32/16_t
Now that the standard gives us proper types for UTF-16 and UTF-32
characters, use them. Will eventually make the code much easier to
read than today, where uint could be an index as well as a char32_t.

It also ensures that the result of e.g. QChar::highSurrogate() can
still be implicitly converted to a QChar now that the
QChar(non-characater-integral-types) ctors are being made explicit.

[ChangeLog][QtCore][QChar] All low-level functions
(e.g. highSurrogate()) now take and return char16_t instead of ushort
and char32_t instead of uint.

effbf147a4 QUnicodeTables: use array for case folding tables
Instead of four pairs of :1 :15 bit fields, use an array of four :1,
:15 structs.  This allows to replace the case folding traits classes
with a simple enum that indexes into said array.

I don't know what the WASM #ifdef'ed code is supposed to effect (a :0
bit-field is only useful to separate adjacent bit-field into separate
memory locations for multi-threading), but I thought it safer to leave
it in, and that means the array must be a 64-bit block of its own, so
I had to move two fields around.

Saves ~4.5KiB in text size on optimized GCC 10 LTO Linux AMD64 builds.

and inserts a :6 padding between the :5 and the :8 and a :2 padding
between the :6 and the :8, growing the bitfield by 8 bits of embedded
padding and another byte to bring the struct back to sizeof % 2 == 0.

Fix by reshuffling the elements and adding a static_assert for the
next round.

Yes, this is necessary. The noexcept operator looks for noexcept tagging,
not at the contents of the function to determine whether to return true.

The more conditionally-noexcept functions are used, the more important it

2fe90a61bd Mark all QChar static functions as [[gnu::const]]
The GCC documentation says that a const function is not allowed to read
global memory. This needs to be clarified: it's not allowed to read RW
global memory. It's fine to read read-only memory, as that is equivalent
to just pure code.

The QChar static out-of-line functions only lookup a property of the
given Unicode character and always return the same value.

The only exception is the decomposition() function, which returns a
QString and is therefore not allowed to be marked const.

9b0fab6b62 Update Qt internals to use QChar::Script
...and remove the outdated QUnicodeTables::Script enum.
QFontEngineData now has one extra slot that never used
(engines[QChar::Script_Inherited]). engines[QChar::Script_Unknown],
if accessed, would be set with a Box engine instance, and could be used
as a minor optimization some time later.

In order to preserve the existing behavior, we map all scripts up to Latin to Common.

f7639c0a6d Add QChar::Script enum
...where the values are not aliased to Common script.

The old QUnicodeTables::Script enum was retained for compatibility reasons
until Qt internals are updated to use QChar::script().
Using QChar::Script instead of QUnicodeTables::Script would improve both
the text analysis (itemization, boundary finding) and the text shaping quality.
This also a required step for switching to Hurfbuzz-NG.

/* This adds 6668 more .rodata bytes */

2fbb69a093 QTBF: Fix issue with no splitting the words at "." (FULL STOP)
As of Unicode 5.1, some punctuation marks were mapped to MidLetter and MidNumLet
for better URL and abbreviations handling which caused "hi.there" to be treated
like if it were just a single word;
until we have the Unicode Text Segmentation tailoring mechanism, retain
the old behavior by remapping (some of) those characters back to their old values.

2672c4fa91 Update the Unicode Data and Algorithms up to Unicode 6.2
Version 6.2 of the Unicode Standard is a special release
dedicated to the early publication of the newly encoded Turkish lira sign.
In addition, there are some significant changes to the Unicode algorithms
for text segmentation and line breaking to improve breaking for emoji symbols.

For more details, see http://www.unicode.org/versions/Unicode6.2.0/

b57e2162ef QUnicodeTables: some internal API renamings
enums GraphemeBreak, WordBreak, and SentenceBreak has been renamed to
GraphemeBreakClass, WordBreakClass, and SentenceBreakClass respectively,
their values has been renamed to contain a '_' as logical enum-value separator
(just like many other nums in Qt, e.g. LineBreakClass);
*BreakFormat has been replaced with *Break_Extend (some format characters are
kind of subtype of the extender characters, not vice versa).

c1329fba13 Clean-up the Unicode tables generator code and the generated header
This fixes the blocks and memory consumption reports, the whitespace issues
and makes the code a bit cleaner.

Since I'm the only one who does change this code, such a no-op commit
could not hurt anyone or even git blame ;)

d8c04d60db Make QUnicodeTables::script() support SMP code points
Instead of expanding the scripts table with script values for the code points
>= 0x10000, it has been merged with the properties table in order to
increase perfomance of the script itemization code (not affected yet).
(Stats: the properties table grew up in 97428-89800 = 7628 bytes;
        the old scripts table was of size 7680 bytes)

The outdated ScriptsInitial.txt and ScriptsCorrections.txt file has been removed
(they were just empty, the "corrigendum" script corrections should be applied
to Scripts.txt directly, *no customization allowed*!).

More script testcases has been added - at least one per supported script.

Task-number: QTBUG-6530
