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().

The main reasons for doing this are:
1. _qpa.h end up in the master QtGui include file. QtGui is meant for
userland applications. qpa code is neither binary nor source compatible.
Inadvertant use of QPA api makes the user code binary-incompatible.
2. syncqt creates forwarding headers for non-private header files. This
gives people the impression that this is public API.
As discussed on the mailing list, even though QPA api is internal and subject
to change, it needs to treated differently from private headers since they
will be used by in-qtbase and out-of-qtbase plugins.
This commit does the following:
1. The _qpa in QPA header files is dropped.
2. syncqt now treats any file with qplatform prefix as a special file and
moves it to qpa/ directory. The recommended way of using QPA API in plugins
is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API
from multiple modules (for example, qplatformfoo might be in QtPrintSupport)
3. The user needs to explicitly add QT += <module>-private to get access to
the qpa api.
4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo
includes.
This commit does not change the cpp filenames. This requires a more careful
merging of existing non qpa cpp files and existing cpp files on a case by
case basis. This can be done at anytime.
The following files are not renamed as part of this changed but will be fixed
as part of a future change:
src/gui/kernel/qgenericpluginfactory_qpa.h
src/gui/kernel/qgenericplugin_qpa.h
src/gui/kernel/qwindowsysteminterface_qpa.h
files were renamed using

for x in `find . -name "qplatform*_qpa_p.h"`; do git mv $x "${x/_qpa_p.h/_p.h}"; done
includes were renamed using script

This change enables us to instantiate a QFontEngineMulti that takes

engines based on the platform. Since this can be quite expensive, we
defer the query for fallback families' names until it's needed and
we cache the resulting multi font engine.

When we request glyphs from fallback fonts, we would potentially
load all fonts on the system into memory. This is especially true
for glyphs that are not supported by any font (or by the last in
the list) in any "Common" script (which e.g. includes CJK).
This would make any application which tried to display unsupported
glyphs use huge amounts of memory for keeping unused fonts cached,
only limited by the number of fonts on the system.
The patch contains two solutions: First, before loading the font,
the multi font engine will be asked whether it needs to be tried
for the given character. By default, this will always be true, so
all fonts will be tried, but with the new font config multi engine
in the platform plugin, it will ask FontConfig whether the font
contains a glyph for the character.
Should the font be loaded and still fail to resolve the character
(which could be the case for other platforms), we will simply
delete it again immediately instead keeping it cached.

Each QFontPrivate points to a QFontEngineData instance, which is
essentially a mapping from different scripts to QFontEngines. Let's
say we have QFont("Waree") and trying to use that for one text in
Thai and another text in English, there should be only one
QFontEngineData: [ QUnicodeTables::Common -> QFontEngineMulti(1),
QUnicodeTables::Thai -> QFontEngineMulti(2) ]. If we cache
QFontEngineData using QFontCache::Key (which includes QFontDef,
script and screen) as the key, then we will create two
QFontEngineData: [ QUnicodeTables::Common -> QFontEngineMulti(1) ]
and [ QUnicodeTables::Thai -> QFontEngineMulti(2) ], so it will be
pointless to have QFontEngineData at all.

Fonts like "Helvetica Neue UltraLight" or "Skia Regular Black
Condensed" can't be selected in Qt because either they don't
report correct numeric values for weight/stretch/etc. or these
values are not mapped from QFont enums in a linear way. Thus
we provide a shortcut to select these fonts with PostScript
name or full name without resorting to family name matching in
QFontDatabase (these fonts are not registered in font database
anyway). After this, we can simply use:
QFont font("Helvetica Neue");
font.setStyleName("UltraLight");
to select these fonts. QCoreTextFontEngineMulti matched like
this can be created directly from the CTFontRef instance
instead of creating from the font name, making this process
faster.
The commit also cleaned up the font loading process in Mac
font database a bit, moving the code for family matching into
a separate function.
Add QFontInfo::styleName() and QRawFont::styleName() to access
the resolved style name for a font.
