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.
[ChangeLog][Important Behavior Changes] QDataStream version bumped up to 19 to account for changes in the serialization of QFont.

If an entire font family is condensed or stretched and we match by
family name, the default stretch factor of 100 will make the font
engine try to synthesize it back to medium stretched font.
The existing code is already made to deal with a stretch of 0 that is
no longer used. This patch reintroduces 0 stretch to indicate no
specific stretch has been requested. Specifically setting stretch to
100 on a QFont will introduce the old behavior.
[ChangeLog][QtGui][QFont] The default value of QFont::stretch() is
now 0 to indicate any default stretch is acceptable.

Parse the requested family before we're looking/saving into the cache,
thus hitting the cached EngineData for:
* quoted family names (eg. QFont("'Arial'"))
* non-simplified family names (eg. QFont(" Arial "))
* substituted family names (\sa QFont::insertSubstitution())
* explicit fallback list, where possible (eg. QFont("Tahoma, Arial"))
This also improves the cache hitting for the font engines in some cases.

We depend on the assumption QFontCache::findEngine(key) for key.multi=1
returns a font engine of type QFontEngine::Multi;
guarantee that by checking it in a single place.

Build it only in -developer-build mode for tests that might depend
on exact-matching font behavior.
Return earlier to avoid doing any useless job.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

1. when there were some engines with ref > 1 in the cache, prior to calling
QFontDatabase::{add,remove}ApplicationFont()/removeAllApplicationFonts()
(QFontCache::clear() has never decreased engine's cache_count);
2. when the QFontEngineData's engine is not in cache i.e. the Box or Test font engine
(~QFontEngineData() didn't free engines it keeps).
Instead of using the font engine's (external) "cache_count" counter,
QFontCache now references a given font engine every time it is inserted to
the cache and dereferences exactly that number of times in clear().
