8761b2b5d9 Print some debugging information for pkg-config detection
Commit d44781730c disabled use of pkg-
config on Mac, which in turn automatically disables all of the tests
that depend on pkg-config too, like D-Bus. If you then use the -dbus
flag, configure would error out telling you that it couldn't find D-Bus,
despite it being there.

Now we print some helpful information on error and extra information for
finding out why it may have got disabled.

b077ed746a allow detection of static/shared target in the config tests
It was not possible to determine whether Qt is being built as
a shared or static library in the config tests, as that information
was not added to QMAKE_CONFIG used in the compileTest function.

For linking to ICU on Windows, there is logic which depends on
it in config.tests/unix/icu/icu.pro, but was broken for the static
target, as the expected library name was not found (icuXX -> sicuXX).

12d32b017d Complete the work for the runtime libdbus-1 support
Commit a2da88712f was incomplete. Though
it did enable building of QtDBus without the libdbus-1 headers, but it
still kept looking for it. We don't need to do it anymore if CFG_DBUS is
the default (runtime), so skip the actual check.

This commit does not change behavior. All it does is skip the D-Bus
tests if we're about to use dlopen'ed libdbus-1.

182bb7c3d0 Fix build on Linux when dbus headers cannot be found
When CFG_DBUS != "no", we enable the build of linuxaccessibility in
src/platformsupport, which requires QT += dbus to work. When no dbus
headers are found, CFG_DBUS is set to runtime, which means we'll
enable a11y but "dbus" will not end up in qconfig.pri and therefore
src/dbus is not built at all (and not before platformsupport). Therefore
the build in platformsupport breaks.

So even if CFG_DBUS is set to "runtime" we need to make sure that dbus appears
in qconfig.pri.

a2da88712f Make QtDBus compile without libdbus-1 headers, if dlopening
Most of QtDBus already needs very little from libdus-1, so create an
extra header containing the minimum API we actually need.

One large advantage of this solution is that now QtDBus can always be
enabled, even if the system doesn't have libdbus-1 installed. This is
interesting on OS X, where libdbus-1 is often installed by Homebrew or
MacPorts, which may include extra libraries we don't want in our
packaging.

37fb892767 Android: Report error when OpenSSL is on and headers are missing
There was an override for Android which would disable the configure
error when doing an OpenSSL build without having the headers
available. This has several times lead to packaging errors where
OpenSSL gets disabled but it's not noticed before the package testing,
which delays the process.

I'm not 100% sure of the reasoning behind the override, but I think
it's a left-over from Necessitas where OpenSSL was statically linked
into Qt.

f1aafb595b Make configure fail on invalid (-no)-feature options
configure script has been silently accepting whatever flags that begin
with "-feature-" even if the feature name does not exist at all.

Since the script validates many other flags, this behavior can make
users believe flags they supply is valid when it isn't.
Besides, this option is currently not protected against typo in any way.

This commit verifies those flags against content of
"qtbase/src/corelib/global/qfeatures.txt" and fails if supplied
flag is not a valid feature name.

70ea4e2b29 iOS: Enable fat builds containing both armv7 and arm64 slices
Apple will from February 1, 2015, require all applications uploaded to
the App Store to be built for both 32-bit (armv7/s) and 64-bit (arm64).

https://developer.apple.com/news/?id=10202014a

We enable fat Qt binaries by passing both -arch armv7 and -arch arm64
to clang, which takes care of lipoing together the two slices for each
object file. This unfortunately means twice the build time and twice
the binary size for our libraries.

Since precompiled headers are architecture specific, and the -Xarch
option can't be used with -include-pch, we need to disable precompiled
headers globally. This can be improved in the future by switching to
pretokenized headers (http://clang.llvm.org/docs/PTHInternals.html).

Since we're enabling 64-bit ARM builds, we're also switching the
simulator builds from i386 to fat i386 and x86_64 builds, so that
we are able to test 64-bit builds using the simulator, but we're
keeping i386 as the architecture Qt is aware of when it's building
for simulator, as we need the CPU features to match the lowest
common denominator.

c0a54efc40 Build Qt for OS X and iOS with relative rpath
Defaulting to absolute_library_soname on configure -rpath is no longer
necessary as now we support @rpath install name ids on OS X and iOS.

This also sets QMAKE_SONAME_PREFIX to @rpath for Qt modules when built with
rpath configuration.

This makes Qt libraries relocatable on OS X. Qt SDK is not yet relocatable
though, because plugin location (including cocoa plugin) is still resolved
using absolute path (see QTBUG-14150), also there are several absolute paths
hardcoded in qmake mkspecs pri files.

538248d930 Android: Don't include Apache code under LGPLv2 license
The code which extracts style assets for the Android style
is licensed under the Apache license, which is not compatible
with LGPLv2.1. It is, however, compatible with LGPLv3. This
means that the Android platform plugin cannot be LGPLv2.1
as long as this code is included.

To minimize licensing confusion, we default to only providing
LGPLv3 for Android. If you want to build a LGPLv2.1-compatible
library, you can add -no-android-style-assets to the
configuration. This will in turn enable the LGPLv2.1 in
the configure output, and it will disable the extraction
code in the platform plugin.

Running the Android style with an LGPLv2.1-compatible platform
plugin will work, but it will look horrible.

[ChangeLog][Android] Default open-source license for
Qt for Android is now LGPLv3. For compatibility with the LGPLv2.1
license, add "-no-android-style-assets" to your configuration.

529a31c967 configure: fix expanding system commands in qmake parser with GNU awk < 4
qmake variables using $$system() were incorrectly parsed by the custom
qmake parser in the configure script, when using GNU awk 3.1.8 or
earlier. They are parsed correctly with GNU awk 4 or mawk.

This was occurring with such an assignement (from an extra mkspecs file):
    QMAKE_CC                = $$system($$CMD QMAKE_CC 2>/dev/null)

The custom qmake parser in the configure script first attempts to
expand $$UPPERCASE variables, before running $$system(), using this:
    match(value, /\$\$(\{[_A-Z0-9.]+\}|[_A-Z0-9.]+)/)

But when using non-ASCII locales with GNU awk 3.1.8 or earlier,
$$system was expanded (to an empty string) because these earlier awk
versions match lowercase letters for the [A-Z] regexp, which is
traditionally used to match uppercase letters.

This behavior has been changed in GNU awk 4.0.0, which only matches
uppercase letters for [A-Z] by default. A workaround for earlier GNU
awk versions is to run awk with the C locale.

See GNU awk NEWS "Changes from 3.1.8 to 4.0.0":
25. Gawk now treats ranges of the form [d-h] as if they were in the C
    locale, no matter what kind of regexp is being used, and even if
    --posix.  The latest POSIX standard allows this, and the documentation
    has been updated.  Maybe this will stop all the questions about
    [a-z] matching uppercase letters.
    THIS CHANGES BEHAVIOR!!!!

86ac3a98b5 Restore Neon "detection" in Qt
We don't actually detect whether the compiler can create Neon code or
provides Neon intrinsics. Most of them do, so that test would be mostly
moot. We removed the detection previously because we couldn't
automatically enable Neon due to leakage of instructions outside the
areas protected at runtime.

Instead, we rely on the mkspec properly passing the necessary flags that
enable Neon support.

This commit does not change that. All it does is verify whether the arch
detection found "neon" as part of the target CPU features. In other
words, it moves the test that was in simd.prf to configure.

It does fix the Neon detection in configure.exe, which was always
failing for trying to run a test that didn't exist
(config.tests/unix/neon).

b7d8613977 nuke -process/-fully-process/-dont-process options
[ChangeLog][configure] The -process/-fully-process/-dont-process options
have been removed due to being unnecessary and counterproductive.

-fully-process has always been broken to a degree under unix (and since
5.0 under windows) - rcc isn't built before running qmake -r, so the
dependencies are unreliable (and there are many warning messages from
qmake).
also, it is a lot slower nowadays, as qmake -r is not parallelized.

-dont-process doesn't make any sense any more - even if you don't need
the Makefile for some obscure reason, the time spent on creating it is
not relevant without the recursion.

this leaves -process as the only option.

5f6af9de48 Add the -qreal option to the Qt ABI information
If -qreal float is passed, fullCpuArchitecture() will now include
"-qreal_float". If something else other than "float" is passed to
-qreal, we'll try to encode it (e.g., -qreal "fixed<int, 7>").

689e8055f5 Add support for single-file multi-target intrinsics in Qt
GCC 4.9 now allows us to #include any and all intrinsics headers, not
just the one for which we're compiling code, a behavior that ICC and
MSVC have had for some time. With that, we're able to have the functions
for different targets in the same source file. See the GCC manual:
  http://gcc.gnu.org/onlinedocs/gcc/Function-Multiversioning.html

This functionality is notified by the QT_COMPILER_SUPPORTS_HERE(XXX)
macro, which indicates that all the intrinsics from
QT_COMPILER_SUPPORTS_xxx are available and enabled. To complement, a
QT_COMPILER_SUPPORTS(XXX) macro is also added.

Unlike ICC and MSVC, GCC requires a special function attribute, which
will also cause code optimization. That's the QT_FUNCTION_TARGET macro.

Note: because of the absence of the target attribute, ICC and MSVC will
not generate instructions with the VEX prefix unless they only exist
with the VEX prefix or if -mavx / -arch:AVX are enabled.

This matches the -ffunction-sections from bootstrap.pro, which tells the
compiler to create a section for each function. The -gc-sections option
tells the linker to drop what wasn't used (normally, it only drops
entire files).

a26e3ecc3d Include GLES 3.0 and 3.1 headers when available
In ES builds configure will now check for OpenGL ES 3.0 and 3.1
availability. This allows qopengl.h to include the correct header
and, by defining QT_OPENGL_ES_3 and QT_OPENGL_ES_3_1, the OpenGL
wrappers can provide support for MapBuffer, VAOs, etc. on GLES 3.0+
too. Right now this is not possible since the only standard way to
use an ES function specific to a given version is to use the function
directly. The extension mechanism (eglGetProcAddress and friends), that
is often used in desktop GL, is not available for such functions.

[ChangeLog][QtGui] QtGui's OpenGL headers are now automatically including
the highest available header (gl31.h, gl3.h or gl2.h) in OpenGL ES builds.

bded052aad Windows: Do not link QtCore against ICU by default
Do not link against ICU on Windows, unless it is explicitly requested
('-icu' configure option). This removes the QtCore->ICU dependency
if ICU was detected in the configure environment.

So far ICU has been used in Qt Core for

- support of a larger set of codecs (805 instead of 135)
- more accurate QLocale functionality (QLocale::toUpper,
  qLocale::toLower)
- string collation

However, for all functionality there are also backends using the
Windows API/Registry (QLocale, QCollator), or built-in
codecs that are part of QtCore. Since the ICU dependency is quite heavy
(3 libs with about 25 MB) it seems sensible to not require it by default.

QtWebkit is unaffected, since it has it's own ICU check.

[ChangeLog][Windows] Changed configure defaults so that Qt5Core does not
link against ICU libraries anymore. Pass '-icu' to enable it.
