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.

On Windows, the wrong value was used to calculate the
design-to-device scale. The assumption has been that tmHeight
in the TEXTMETRIC is the pixel size of the em square, but
it is not, it's the height of the font (ascent + descent).
The pixel size of the font is defined to be the em square size
in pixels.
On OS X, the kerning data was never actually read from the
font. I've added a lazy initialization for this similar to
the one in the FT engine.
This was discovered when investigating QTBUG-48546, as it turned
out that the kerning information extracted by Qt in this case was
different from the one used by Harfbuzz.
I've changed testfont.ttf to kern "_2" so that the digit is positioned
directly on top of the underscore and constructed a test.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license

The auto-hinter in the FreeType version bundled in Qt gives
slightly different advances on some glyphs. As noted in
the removed code, this was already observed on Windows and QNX,
and recently also on Android.
I'm sure it could also happen on platforms using the system library
if the system library was the same version as the one bundled in Qt.
Instead of expect-failing the test, we simply accept both the
observed results as valid.
Note that we need to accept 9 as a result for the default hinting
preference on all platforms, not just Windows, since the default
hinting preference in FreeType can be a system setting.
