By depending on setFamilies() then we can be sure that font names with
spaces, commas, quotes and so on are correctly handled without being
misinterpreted. For now it will split on the comma when a string
containing one is passed to setFamily. But from Qt 6.2 this will be
removed to preserve the family string as a convenience function.
[ChangeLog][QtGui][QFont] Indicated that setFamilies/families is
preferred over setFamily/family to ensure that font family names are
preserved when spaces, commas and so on are used in the name.

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.

Quite a big change since it has been several years since
the last update. This drops the Harfbuzz source on top
of the existing code in Qt, and does the following
additional changes:
1. Deletes old source files that have been removed upstream
(everything named foo-private.hh is now renamed to just
foo.hh for instance).
2. Added a header guard to config.h because it may be
double-included.
3. Implement a memory barrier needed by hb-atomic.hh.
4. Changed the signature of hb_atomic_int_impl_add()
to take a pointer to match new upstream.
5. Updated .pro file to include new files and removed
old.
6. Updated qt_attribution.json
7. No longer disable deprecated APIs since
hb_ot_tags_from_script() is now deprecated and is used
from Qt code.
8. Updated and applied the patch in patches/ for CoreText.
9. Updated tst_qtextscriptengine::thaiWithZWJ() according to
changes in Harfbuzz and disabled it for system-harfbuzz,
since this may be an older version of harfbuzz depending on
the system.

In the past, we had an undocumented text flag that worked with
one of the QPainter::drawText() overloads. This was never intended
as public API and served a specific cause in Qt WebKit at one point.
But there is a general need for such API, as disabling shaping features
easily gives 25% performance improvement on text rendering even for
fairly short strings.
This patch adds a new style strategy flag to disable shaping and
will just uses the CMAP and HDMX tables to get glyph indices and advances
for the characters. In Qt 6, the TextBypassShaping flag can be removed
completely and be replaced by the style strategy.

- they don't have a mapping to the thai encoding tis620 which libthai
requires. However it is an unfortunate fact that there are many websites
etc that liberally place these ZWJ and ZWNJ characters throughout thai text
to force word boundaries, so we must also deal with them.
We deal with all Inherited characters by mapping them to the invalid code ~0
in tis620 encoding, following what libthai does internally in its own tis620
encoding functions, and then replacing this character with the original
unicode and setting dontPrint to true to hide the ZWJ and ZWNJ
characters.
Includes a unit test to check the behaviour.
