d964981252 Remove ARMFPA support and Q_DOUBLE_FORMAT detection
Remove the -armfpa option the config.tests/unix/doubleformat*
detection. The places where we used QT_ARMFPA and Q_DOUBLE_FORMAT
has been removed as well.

Rationale: ARM FPA with GCC does not work with EABI. Qt currently
does not support compiling without EABI, making ARM FPA an
impossibility. It is unknown whether other compilers provide ARM FPA
support with EABI. Support for ARM FPA can be re-added in the future
should the need arise, but since ARM VFP is available for ARMv5 and up,
we should encourage implementors to instead use soft-floats or VFP.

cc78f47778 Allow using multi fontengine in QTextLayout with QRawFont.
This change enables us to instantiate a QFontEngineMulti that takes
the raw font's font engine as its primary engine but can use fallback
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.

10ac807085 Add support for QRawFont in QTextLayout.
The purpose of this change is to allow shaping complex
text while using QRawFont.
This is needed for WebKit so that we can switch to
using QRawFont everywhere and be more in line with
what other WebKit ports do.
Since this change slightly bends the aim of QRawFont,
let's reserve this for internal use for now.

762a721f7f Fix buffer overrun crash running MSVC2010 win32 Qt on win64
When loading dnsapi.dll as a plugin, we experience crashes because
the calling convention is not specified.
The default is _cdecl, but __stdcall (via the WINAPI macro) should
be used for windows APIs.
Mismatched calling convention results in corruption of local variables,
probably because the stack pointer is incorrect and SP offsets are
used in optimised builds rather than frame pointer offsets.

Since the library has been available since Windows 2000, I don't
think that we need to load it dynamically.
(Unlike the unix version where it isn't part of the LSB)

Also checked that the current release of mingw works.

fe092d1a6d Add support for _NET_ACTIVE_WINDOW on xcb
Use a _NET_ACTIVE_WINDOW client message instead of xcb_set_input_focus
for activating toplevel windows on xcb.

According to the Extended Window Manager Hints the right way to activate
a top-level window is using _NET_ACTIVE_WINDOW (when it is supported by
the WM). Other approaches like calling xcb_set_input_focus should be
avoided when possible, since the WM cannot intercept them.

46e4a9d523 Windows - fix getsockopt calls for narrower than int options
Windows unhelpfully writes to only one byte of the output buffer
when getsockopt is called for a boolean option. Therefore we have
to zero initialise the int rather than initialising to -1 as was
done before.
This in general only works for little endian architecture, because
the word would look like 0x01000000 on big endian. So I have added
some compile time asserts in the assumption that windows is always
little endian. This is ok for comparisons with 0/false, but not
comparisons with true or nonzero values.
In the case of IPV6_V6ONLY, it is documented as DWORD (unsigned int)
but on some windows versions it is returned as a boolean triggering
the warning. I removed the warning, as the conversion to int works on
both LE and BE since it is only compared with zero.

e500946de9 QHeaderView - remove sectionCount variable
A previous patch ensures that we have exactly one section in a Span.
( see SHA : b800d8b94a )

Therefore we no longer need the sectionCount variable. We have
assess to it through the sectionSpan.count.  To keep this patch
quite simple the variable sectionCount has been changed to a
function returning the count value.

6363672163 Add support for QT_NO_SIGNALS_SLOTS_KEYWORDS
QT_NO_KEYWORDS can be used for example to ensure that foreach can
not be used, but Q_FOREACH must be, that slots must not be used but
Q_SLOTS must be, etc.

Typically they are used to avoid symbol conflict with other
libraries that may use the same keywords (I think boost uses
signals).

For 3rd party libraries, it makes sense to use Q_SLOTS and Q_SIGNALS
instead of slots and signals, so that downstreams can still choose
to use QT_NO_KEYWORDS in their code.

The most convenient way to enforce that currently is to define
QT_NO_KEYWORDS when building the 3rd party library. However, that
has the inconvenient side effect of making foreach, forever and emit
not usable within the library implementation.

This patch makes it possible for the 3rd party library to use
QT_NO_SIGNALS_SLOTS_KEYWORDS to exclude signals and slots without
affecting whether the other keywords can be used in the library
implementation.

aac821c220 QRingBuffer: make constructor explicit
This is a private class, but it's so close to
the classical Stack(int) example for explicit
that I just have to make this ctor explicit,
too:

   QRingBuffer rb = 0; // oops: meant '*rb'

now no longer compiles.
