- Replace Nokia contact email address with Qt Project website.
- Remove "All rights reserved" line from license headers.
As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

Remove unnecessary use of QT_ARCH_ARMV6 from qglobal.h (QT_ARCH_ARM is
always defined when QT_ARCH_ARMV6 is defined), and fix the use of
QT_ARCH_ARM to assume ARM < v6 in qblendfunctions.cpp (use QT_ARCH_ARMV5
instead).

This gives a nice speedup for blitting of small and medium sized
images by using preloading and avoiding function call overhead to
memcpy for each scanline. For larger image widths memcpy becomes more
efficient.
Speedups of up to 40 % for 64 pixel wide images were measured.
For image widths between 2 and 16 the speedup ranges between 12 %
and 28 %.

On the N900 16 bit text blending is 30 - 50 % faster, and ARGB32PM
on RGB16 image blending now runs in 1/10th of the time it used to.
We now make ARGB32PM the default pixmap format for alpha pixmaps instead
of ARGB8565PM which is unaligned and bad for performance.
The relevant numbers:
Mostly opaque pixels:
ARGB24 on ARGB24 using QPainter..................: 336,813033
ARGB32 on ARGB32 using QPainter.................: 18,419387
RGB16 on ARGB24 using QPainter..................: 167,301014
RGB16 on ARGB32 using QPainter..................: 17,279372
ARGB24 on RGB16 using QPainter..................: 35,100147
ARGB32PM on RGB16 using QPainter................: 15,924256
No opaque pixels:
ARGB24 on ARGB24 using QPainter..................: 412,190765
ARGB32 on ARGB32 using QPainter.................: 16,818389
RGB16 on ARGB24 using QPainter..................: 170,957878
RGB16 on ARGB32 using QPainter..................: 16,742984
ARGB24 on RGB16 using QPainter..................: 93,600482
ARGB32PM on RGB16 using QPainter................: 15,999310
So switching to ARGB32PM should give a boost in all areas.

Adds new NEON configure test and -no-neon configure option. NEON
implementations can also be turned off by setting the QT_NO_NEON
environment variable.
Performance improvements (in frames per second):
- Blending ARGB32 on RGB32/ARGB32, mostly opaque: 71 %
- Blending ARGB32 on RGB32/ARGB32, no opaque pixels: 108 %
- Blending ARGB32 on RGB32/ARGB32, with 0.5 opacity: 158 %

We want to force use of qreal where possible. This can lead to better
performance on platforms where qreal -> float (i.e. ARM). To achieve
this we:
1. changed from 'double' to 'qreal', where justified
2. using qreal() to intialize constants, where justified
3. adding helper functions that are overloaded for qreal
like qAtan2(), qAcos(), qFabs() ...
4. defining QT_USE_MATH_H_FLOATS for Symbian platform
In addtion we used opportunity to improve code with some small things
5. converting divisions to multiplications
(i.e. '/ 2.0' -> '* qreal(0.5)')
6. defining new constants (i.e. 'Q_PI / 180.0' -> 'Q_PI180')
7. declaring variables as 'const', where justified

In qt_scale_image_16bit() and qt_scale_image_32bit(), when a sample
point was located on the border between two pixels in the source image,
the sample point was rounded up instead of down. If a sample point was
exactly on the bottom or right edge of the source image, the function
would therefore sample a pixel outside the image. Because of how the
target rectangle is rounded, a sample point will never be exactly on
the top or left edge of the source image, so we will not get a similar
problem there.
I extended the lance test pixmap_scaling.qps.

Add SuperH to the ever growing list of architectures which can't
correctly dereference a short* which is not 16-bit aligned. Turning this
into a white-list rather than a black list might make sense at some
point, but as QT_ARCH_I386 isn't defined on windows, the white list
looks even uglier at the moment. :-)
