Make sure that the compiler is strict in QtCore

ICC defaults to "fast math" mode, which allows it to do non-compliant
operations that may or may not result in unexpected values. Generally, it's
ok, but apparently the code in qlocale_tools.cpp is too complex, so we're not
taking chances.

I can't rule out an issue in the code, though.

Make unicode ranges in font take precedence over codepage

Change 4b2c73b4767bcb512cbc17f65186eac5d004db07 triggered a
regression on Android, because the DroidSansFallback.ttf font
has codepage ranges that list Arabic as a supported codepage
despite the fact that the font has no glyphs for Arabic.

If a font has valid unicode ranges which does not specify
support for e.g. Arabic, then the code page ranges for the
same script should be ignored.

[ChangeLog][Android][Fonts] Fixed support for Arabic text.

QtConcurrent: Extend workaround GCC bug 58800 in median calculation

GNU/Linux distributions like Fedora update the __GLIBCXX__ date (e.g.
because of applied extra patches on top) and thus make the current
workaround useless. As long as no official gcc/libstdc++ version is
released, we can increment the "upper bound" date to cover such cases.

Unify glyph format between QFontEngine and QFontEngineGlyphCache

Instead of the glyph cache having its own cache type that always mapped
one to one to a font engine glyph format, causing confusion and needless
conversions, the glyph caches now use QFontEngine's glyph format enum.

This also removes the iffy use of an int for the glyphFormat in the font
engines.

Unify alpha map padding in CoreText font engine

Instead of padding the image size manually, we rely on alphaMapBoundingBox
to give use the right glyph metrics.

Prevent top/left clipping of anti-aliased glyphs in CoreText font engine

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.

network: add support for the SPDY protocol

Currently the only supported SPDY version is 3.0.

The feature needs to be enabled explicitly via
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.

Task-number: QTBUG-18714

[ChangeLog][QtNetwork] Added support for the SPDY protocol (version
3.0).

QHash: use prime numbers when rebucketing

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.
