excluding 3rdparty, test-data and auto generated code.

Note A): the only non 3rdparty c++-files that still
have trailing whitespace after this change are:
* src/corelib/codecs/cp949codetbl_p.h
* src/corelib/codecs/qjpunicode.cpp
* src/corelib/codecs/qbig5codec.cpp

Instead of setting -isysroot in both arch.test, compile.test, the various
mkspecs, and sdk.prf, we now propgate the chosen SDK as the qmake
variable QMAKE_MAC_SDK, which is then handled exclusivly in sdk.prf.

The QMAKE_MAC_SDK variable, and -sdk argument to configure, is expected
to be of the short-form name, eg macosx or iphoneos, not a full path, as
that's what Xcode also expects. We take care of translating that into
a full path for -isysroot/-syslibroot in sdk.prf, using xcodebuild as
a helper.

eventfd(7) uses less resources than a pipe, as it only needs to store a
single 64-bit integer, as opposed to a full buffer.

It was introduced first on Linux version 2.6.22 and glibc 2.7. However,
both the configure-time test and the runtime usage require the use of
EFD_CLOEXEC for thread-safety, so this code will be enabled only for
Linux 2.6.27 and up as well as glibc 2.9 and up.

Some of the xcb- libraries we depend upon are not (yet) common across

on different distributions. The patch mitigates this by:

Adding the files from
  libxcb-proto (version 0.1.6), compiled with libxcb-1.5
  xcb-util (version 0.3.9)
  xcb-util-image (version 0.3.9)
  xcb-util-keysyms (version 0.3.9)
  xcb-util-renderutil (version 0.3.8)
  xcb-util-wm (version 0.3.9)

from xcb.freedesktop.org/dist to src/3rdparty/xcb.

Adding a configure option '-qt-xcb' to use the sources instead of
linking to the respective runtime libraries.

The tests themselves required a bit of changes to compile with

didn't like the volatile variables, which GCC, Clang and ICC have been

dead code must be syntactically correct. We're not running the output.

support AVX2 is -mavx2, but ICC does not support it (yet), requiring
-march=core-avx2 or -xCORE-AVX2. That flag, instead, enables support
for all the features that the "Core-AVX2" processor (codename Haswell)
will support. And clearly, the MSVC flags are different.
