Disassembly shows the Intel compiler does expand to SIMD, but a much
worse code than ours. Clang 3.4 does generate a compact SIMD version,
probably of the same quality as our hand-written code. And GCC 4.7
through 4.9 don't generate SIMD at all.
So let's use the most efficient version.

The tst_Collections test does not compile under strict-iterator

The strict iterators required a small change: the difference_type
typedef needs to match the operators that get distances
(operator-(iterator)) and move the iterator around (+, -, +=, -=, etc.).

So far we did bind the definition of Q_COMPILER_VARIADIC_MACROS to
C++11 (so gcc, clang will not define it in default gnu++98 standard).
However, variadic macros are a feature of the gcc preprocessor since
version 2.97, and are enabled in the default configurations on gcc, clang,
icc.
This might cause warnings and errors though if one enables additional
warnings in gcc, clang (e.g. by -pedantic). Anyhow, as a precedent
qglobal.h already relies on 'long long' ... The warning can be disabled
by adding '-Wno-variadic-macros'.

a wrong size (to be more specific width) for FreeType fonts.
The calculation of glyph advances has to to reflect (rounded)
integral number of pixels. This was only done when the glyph was cached.
So in some cases the first call to QFontMetrics::size gave a different
result than the second.

platforms, on BlackBerry for instance it did not. Extended the test

QHash uses an array representing the difference between 2^i and
the next prime; when growing, it calculates 2^x + array[x] (with
`x' representing the "hash table size in bits").
For some reason lost in history the differences are actually wrong
and the calculation above leads to using composite numbers.
Hence: use the right sequence and always produce primes. The right
sequence is actually A092131 from OEIS: http://oeis.org/A092131
Note that the sequence starts at A(1), but we need A(0) too.
Also we truncate the sequence to when growing too much, just like
the old code did, and use powers of two in that case instead.

Currently the only supported SPDY version is 3.0.

QNetworkRequest::SpdyAllowedAttribute. Whether SPDY actually was used
can be determined via QNetworkRequest::SpdyWasUsedAttribute from a
QNetworkReply once it has been started (i.e. after the encrypted()
signal has been received). Whether SPDY can be used will be
determined during the SSL handshake through the TLS NPN extension
(see separate commit).
The following things from SPDY have not been enabled currently:
* server push is not implemented, it has never been seen in the wild;
in that case we just reject a stream pushed by the server, which is
legit.
* settings are not persisted across SPDY sessions. In practice this
means that the server sends a small message upon session start
telling us e.g. the number of concurrent connections.
* SSL client certificates are not supported.

Padding the bounding rect was not enough, as we failed to shift the glyph
accordingly so that it would end up in the center of the bounding rect.
We also didn't take subpixel-positioning into account, which may shift the
position of the glyph too far to the right to be within the image size that
we reserve.
There are still cases where the glyphs seem clipped compared to the same
text rendered with CoreText, but that's because we end up shaping the
text slightly differently, resulting in different subpixel positions
than what CoreText chooses.
