Cap height is an important metric of font, in particular it is
required to make decent implementation of "initial-letter"
CSS property in QtWebKit.
Note that some fonts lack cap height metadata, so we need to
fall back to measuring H letter height.

This allows us to pass pointers to storage that is not an array of
uchar, which it hardly ever is.

The printf-style version of QDebug expands to a lot less code than the
std::ostream-style version. Of course, you pay in type safety (but
compilers warn about it these days), you cannot stream complex Qt
types and streaming QStrings is awkward, but in many cases you
actually improve on readability.
But the main reason is that something that's not supposed to be
executed under normal operation has no business bloating executable
code size.
This is not an attempt at converting all qWarnings() to printf-style,
only the low-hanging fruit.
In this first part, replace
qWarning() << "...";
with
qWarning("...");
In QTransform shared warning strings.
Saves 3KiB in text size on optimized GCC 5.3 AMD64 builds.

From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see

Updated license headers to use new LGPL header instead of LGPL21 one

Specifically when reading files with broken cmap tables, we could
get some undeterministic results. We handle this more gracefully
by verifying that the offsets are sane and bailing out early if not.
This replaces the current pattern throughout the font engine for
consistency.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

Extend the QImage format with two 8-bit grayscale and alpha formats.
These formats have the advantage over Indexed8 that they have simpler
conversion and can be rendered to by the raster engine.
[ChangeLog][QtGui][QImage] Added support grayscale and alpha 8-bit
formats which can also be rendered to.

QFontEngineQPA was really QFontEngineQPF2, and has been renamed. The
multi font engine in qfontengine_qpa.cpp was really a base implementation
of a multi font engine, used by other multi font engines, and has been
renamed and moved accordingly into qfontengine_p.h/cpp.
