Export of color transparency component is added for cases where color
is exported to html. New static function colorValue() is added to
prepare CSS string representation of QColor. When the color is opaque,
it falls down to QColor::name() method which was used previously,
otherwise it returns 'rgba()' CSS statement or 'transparent' keyword in
case transparency is 0.
6-digit precision is used for alpha value as it's maximum which can be
processed properly by Gecko and Webkit engines
(http://lists.w3.org/Archives/Public/www-style/2009Dec/0295.html).
Import part for rgba() statement was also added to QCssParser. It
supports rgba() color values as stated in CSS Color Module Level 3
(http://www.w3.org/TR/css3-color/#rgba-color).
Import of undocumented statement 'rgba(int,int,int,int);' was also
added to preserve regression test success and to provide compatibility
with previous code relying on this behaviour.
Test cases added to QCssParser autotest for rgba(int,int,int,float)
statement and to QTextDocument autotest for rgba(int,int,int,float)
and 'transparent' statements for certain 'color', 'background-color'
and 'bgcolor' properties.

by avoiding the glyph metrics calculation when those metrics weren't requested
(QFontEngine::GlyphIndicesOnly flag has been passed).
As a side effect, this fixes a crash in case QGlyphLayout
was initialized only partially (with the glyphs array and the size).

If the used font engine is of type QFontEngine::Multi, then we already have
both the "font engine runs" and the stripped glyph indicies for the kerning
-> just call the actual font engine's doKerning() method.
If the font engine is not of type QFontEngine::Multi, then we could safely
avoid the glyph indicies extra manipulations.

When Qt is being compiled and is using the bundled zlib, QtCore needs
to export the zlib symbols, since zlib is needed in other Qt
libraries as well. That gives a danger of a potentially disastrous
symbol clash if the user later on links with both Qt and an external
zlib (ref. e.g. QTBUG-15071).
This commit enables a zlib compilation flag that causes all zlib
symbols to be redefined with a prefix. Hence, they will not clash
with a standard zlib.
A minor drawback is that zlib.h will now have #defines for a few
semi-normal identifiers. Hence, a couple of more changes are done:
In the private qzip code, the identifer crc32 had to be renamed.
QHttpNetworkReplyPrivate needed no change, but as a defensive measure
the #include <zlib.h> is moved from the _p.h file to the .cpp file,
to avoid surprising compilation errors later in code that include
that header.
This commit does not in itself solve the issue of how to let Qt
libraries outside of qtbase use the same bundled zlib, but it is
a prerequisite for that.

to keep them consistent with positions for all other flags.
This changes the internal behavior so that attributes[0].lineBreakType now means
"break opportunity at start of the text (before the first character in the string)"
and is always assigned with HB_NoBreak to conform rule LB2
(see http://www.unicode.org/reports/tr14/#LB2).
The current implementation is based on the sample implementation from tr14
that aimed to be as simple as possible rather than to be optimal.
From now, we can use pieces of the attributes array "as is"
without having to adjust some positions. Or we can analize some long text
by chunks (e.g. paragraph by paragraph) and consume less memory.
This introduces a minor overhead that will be eliminated shortly.

For high resolution or extremely large font sizes, the advance
cached here is likely to overflow, since FreeType returns 26.6
fixed point value and we only take signed char here for advance.
In those cases we should skip caching because there won't be
that many big glyphs after all.
Also move the metrics caching block a bit down to take glyph
embolden and oblique into account.
As a result we also don't need to increase the linearAdvance
size because any linearAdvance less than 128 should fit in
the old 10.6 fixed format.

QTextLine::cursorToX returned the line width for cursor positions
outside the width of a wrapped right to left line because the
leading space width was always calculated as 0.
Returning a non-zero width for the leading space does cause
problems for other uses of QTextEngine::alignLine() though
as the textAdvance already doesn't include the leading/trailing
space so subtracting it there double accounts for it.

The only use for storing charset loaded by fontconfig in font engines
is for determine if a font supports certain codepoint, however FreeType
already does that. The charset loaded is sometimes not complete, for
instance in fontconfig 2.9.0 it removed Apple Roman platform support
for cmap loading, thus results a regression in common symbol fonts
(Wingdings, Webdings) rendering. Because those symbol fonts produced
by Monotype only contain two cmap tables: Apple Roman and Microsoft
Symbol, since the Microsoft Symbol table has a weird 0xF000 offset,
we always fallback to the Apple Roman cmap table.
Removing freetype charset cache also make each font engine consuming
less memory.
