If it is a fallback font, then it should just have family set to that
font so it does not get interference from what the families were
originally set to.

QFontDatabase is a singleton and all instances would share
a single, mutex-protected global data pointer. But some functions
were implemented as non-static functions. This caused a lot
of code on the form
QFontDatabase().families(...)
since there was no static access. Other functions were implemented
as static.
To consolidate, we make all functions static. This should be
source-compatible, but not binary compatible.
[ChangeLog][QtGui][Fonts] Some functions in QFontDatabase were in
principle static, but previously not implemented as such. All
member functions have now been made static, so that constructing
objects of QFontDatabase is no longer necessary to access certain
functionality.

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.

Since iOS 13, the cascade list for the default UI font contains
meta-families for several writing systems, such as CJK. Since
these font families were never populated to the database, we ignored
them in Qt, and thus got missing glyphs for the characters in question.
The fix is to make sure these fonts are populated in the database.
It contains a partial backport of 922d195020d54d7e599d135f6a5e0338100e08f1,
which adds the qt_isFamilyPopulated() accessor to allow us to check
if the family has been populated in the font database. In Qt 5.14,
there is public API for this in QPlatformFontDatabase, so this is
a temporary resolution until then.

If the user specifies a font family in their application that doesn't
exist in the system, or one that uses the localized family name, we
will end up resolving the family alias for all fonts in the system,
which typically adds 600-800ms of startup time. Let the user know
when this happens.

Since it was added in Qt 4.2, addAppFont() has been written
to first register the font, then immediately invalidate the
font database and later reload the font again the next time
the db is used. This caused all application fonts to be
reloaded *at least* once, an operation which can be quite heavy
for large fonts, such as CJK fonts. If an application loaded
multiple fonts at different stages of execution, you could
end up loading the same fonts a large number of times, since
all application fonts would be reregistered every time a new
one was added.
When calling removeApplicationFont(), this is okay-ish, since
we need to remove all traces of the font from the platform
database and clearing the whole thing is a convenient way
of making sure there is nothing left. There might be more
efficient ways of doing this, but unloading fonts is not
a common operation, so it is fine to keep this behavior there.
This change removes the invalidation of the font database from
addAppFont(), since this should not be necessary as long as we
are adding fonts. It also removes the reregisterAppFonts flag,
which was a bit of a convoluted way of saying that the database
had been invalidated and needed repopulating. Instead, we use the
same mechanism as for repopulating the system database: We just
check if it is currently empty, which means it has been
invalidated and the application fonts have to be reregistered.
It does not touch the logic in qt_cleanupFontDatabase(), which
is kind of broken (it will leave application fonts in memory
and reregister them if the application continues to run). But
this is only actually called during shutdown (from application
destructor).
[ChangeLog][QtGui][Text] Fixed an issue where application fonts
would be parsed multiple times, causing some unnecessary overhead
when during application startup.

$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} +
It can be easily improved (e.g. for store check that there are no commas
after the opening parens). The most common offender is QLibrary::load,
and some code using std::atomic directly.

9204b8c31ea1b5f0c05870c5b5d74c33b1a4f622 broke font matching on Windows.
This was then attempted fixed by bcd2fa484a4fe93e77743195d7f72cce9e580d43,
but this caused an infinite recursion for some cases, so it was reverted
again by 9d1905da9c59e9062a157199c81c076efc20eb28.
The original issue was that if we populate a specific face of a family,
such as "Arial Black", then the typographic/preferred name will be
detected as "Arial" and this family will be set as populated=true, even
though we have not yet registered any additional subfamilies. In this case,
we need to call populateFamily() for the typographic family name to
ensure we get Windows to enumerate all the subfamilies in that family
before it sets it as populated=true.
But this broke for some fonts where the font naming was unconventional.
In particular, "Yu Gothic" would have its Japanese name as the
typographic name, and there would be no font in the system where
the old-style font family name matched the typographic name. In
that case we would go into a loop where we would try populating
"<Japanese font name>", Windows would translate this to "Yu Gothic", we would
translate it back to "<Japanese font name>", ad infinitum.
In order to avoid the infinite recursion, we add a recursion guard
as well, ensuring that we never call populateFamily() for the main
family we are currently populating.
[ChangeLog][Windows][Fonts] Fixed a bug where it would be impossible
to request different faces of a font family after a specific type face
has been in use.

9204b8c31ea1b5f0c05870c5b5d74c33b1a4f622 broke font matching on Windows.
After this change, if you request a specific face of a family, such
as "Arial Black", and Qt detects that its typographic/preferred name
is "Arial", then it will be added as the single style of the Arial family,
which will in turn be set as populated=true.
So if you later request a regular font of "Arial" family, then it will
see that the family has already been populated, skip this step, and
then see that there is only one style available, i.e. "Arial Black".
To work around this, we need to make sure the typographic family is
properly populated the first time it is registered.

Since the comma character was originally used as a separator, we
need to extend QFont to have setFamilies() so that we can avoid
joining the family strings together. This enables us to see the
family name as a single string and for multiple family names,
we have families().
Subsequently, this has added functions to QTextCharFormat to
account for multiple font families too. So it is now possible to
set a single one directly with setFontFamily() and multiple ones
with setFontFamilies().
This also bumps up the datastream version to 19 as QFont now
streams the families list as well.
[ChangeLog][QtGui][QFont] Add setFamilies()/families() to aid using of font families with commas and quotes in their name.

When showing a condensed font with AnyStretch, we should
not apply any stretch to the font (and if a stretch is
requested, we should calculate the actual stretch based
on how much the font is already stretched or condensed).
This usually works as expected, however, when using
QFont::NoFontMerging as the style strategy, we would
scale the glyph advances by the stretch of the font
since the calculated stretch of the font engine would
be overwritten by the actual stretch. In the case where
we use font merging, this would be done for the multi
engine, so we would not get the same issue, since the
text engine gets the stretch from the actual font engine
and this still has the original, calculated stretch
set.
Note on the test: We can't use testString() for this,
since it contains a space, and the test font does not
have a glyph for this, so we will end up merging a
different font for the space, giving us a slightly
different advance.

After we stopped sanitizing the fallback font list (with change
6ca48a847a1805c3826004c5b989b4ae14397a37), we now need to make
sure it is ordered so that the fonts that support the writing
system in question are always tested first, otherwise we can end up
loading a lot of fonts that will never be used.

We currently match font family names in cross-platform code, before
asking the system to load it. In the case of an empty family name, we
will return the first font in the list which matches the other
conditions.
After that, though, we would pass the empty family name to the
platform font database, and some old platform-specific matching
was invoked. In the case of Windows, we would default to
MS Sans Serif, which is the old Windows 1.0 raster font and which
is probably used by Qt exclusively in the world at this point.
The problem in the end was that the font info would be out of sync.
If the font matched by Qt happened to be smoothly scalable, then
we would treat MS Sans Serif as smoothly scalable, giving us
random glyphs when displaying text in Qt Quick. We would also
overwrite the family name with the one matched by Qt, so even
when MS Sans Serif was used to render the text, we would report
that it was something else.
For empty font families, we therefore pass the family we have
actually matched into the platform database. This will have
the side effect of trusting the font matching in Qt, but only
for the rare case where someone actually explicitly sets the
font family to the empty string.
Note that the random glyph bug that triggered the investigation is not
happening anymore after 1eedfd0e66c7afd682f682a659cda2942485cd08
because we will detect the glyph outlines as unreliable in the
MS Sans Serif font now instead of trusting the smoothly scalable
flag. But there would still be a mismatch between the font used
for rendering and the matched font.

Getting the localized family name of a font involves quite a bit of work
internally in CoreText, e.g. creating and sorting font descriptors.
By deferring population of family aliases until a font match misses
we shave off ~1 second of startup time for applications that use non-
localized font families (most applications).

This will be used by QtQuick to correct a performance regression introduced by
592614ea3ecd90ede2ae1b8e6579d1b898f474ec -- QFontDatabase::isSmoothlyScalable is
quite computationally expensive; and now it is unconditionally expensive
regardless of the platform.
