5bb178c479 Say hello to Android multi arch build in one go
Multi arch build in one go is need to support the new .aab packaging format.

By default the users apps are built for all Android ABIs: arm64-v8a armeabi-v7a x86_64 x86
The user can pass ANDROID_ABIS to qmake to filter the ABIs during development,
e.g. qmake ANDROID_ABIS="arm64-v8a armeabi-v7a" will build only for arm ABIs.

[ChangeLog][Android] Android multi arch build in one go,
needed to support the new .aab packaging format.

39e937a538 Fix host architecture detection for canadian cross builds
If the host architecture is different from -platform (canadian cross
build with -external-hostbindir) then we cannot use QMAKE_HOST.os to
deduce the executable extension for that platform, because this value
comes from the qmake binary that was pointed to by
-external-hostbindir.

Move the target name deduction mechanism to the actual configure test
.pro files to make sure the right scopes are available, and write the
deduced target name to a text file. That text file is read by
qtConfTest_architecture to get the right binary to analyze.

37352b23a9 x86: Disable AVX support on 64-bit MinGW
GCC for 64-bit Windows has a bug that it fails to properly re-align the
stack pointer for use with 256-bit memory addresses (AVX). Therefore,
there's about a 50/50 chance that any function using AVX will have an
improperly-aligned stack. In release mode, stack accesses should be
rare, but in debug mode they happen frequently. Either way, this is a
ticking time bomb, so we disable.

Clang is not affected.
32-bit MinGW is not affected.
64-bit in other OSes with GCC are not affected.

2708c6c11d OpenSSL: force the "1.0.0" soname when loading OpenSSL 1.0
Some Linux distributions patch OpenSSL's soname, making builds
on such distributions not deployable elsewhere. The problem is that
the code loading OpenSSL symbols would attempt to use the soname
of the build machine, and therefore not finding the OpenSSL
libraries on the deploy system.

The binary builds of Qt for Linux are affected by this problem,
as they build under RHEL7.4 which changes to soname of OpenSSL to
a non-standard string. This makes the binary builds not pick up
OpenSSL 1.0 from the machine where the build gets installed on.

Given that in the pre-1.1 versions only the 1.0 series is supported,
bump the minimum requirement of Qt to that. The 1.0.x releases
(up to 1.0.2, at the time of this writing) have kept binary
compatibility, and advertise a soname of "1.0.0", which is used
by most distributions.

So, if loading of OpenSSL with the build-time soname fails,
try to load them with the "1.0.0" hardcoded soname.

[ChangeLog][QtNetwork][SSL] OpenSSL >= 1.0 is now required to build
Qt with OpenSSL support.

d241616e41 AVX512 test: an intrinsic that GCC forgot to implement prior to GCC8
_mm512_mask_cvtepi32_storeu_epi8 is VPMOVDB (convert from 32-bit to 8-bit
with truncation) where the destination is a memory address, with an
OpMask register used to indicate which of the lanes in the vector to
store. Similarly, _mm512_mask_cvtepi16_storeu_epi8 is VPMOVWB (convert
from 16-bit o 8-bit), which is useful for UTF-16 to Latin1 conversion.

2cf5c5a602 SIMD: Remove unused (and unlikely to be ever used) AVX-512 profiles
"AVX512MIC" (Many Integrated Cores) is the set of AVX-512 features found
on the Intel Xeon Phi coprocessors (codename "Knights Landing"), which
is an unlikely architecture for Qt to run on.

The two profiles with VL came from study of early GCC code and are no
longer applicable. GCC source code now shows both VBMI and IFMA as part
of the -march=cannonlake feature set.

cf63b0e1df qsimd: add support for new x86 CPU features
This adds detection for: VAES, GFNI, AVX512VBMI2, AVX512VNNI,
AVX512BITALG, AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS. These
features were found in the "Intel® Architecture Instruction Set
Extensions and Future Features" manual, revision 30. This commit also
adds support for RDPID (already in the main manual) and the Control-flow
Enforcement Technology, which appears in a separate Intel paper.

This new support was done by adding a new generator script so we don't
have to maintain two tables in sync, one in qsimd.cpp with the feature
names, and the other in qsimd_p.h.

Since we now need a lot more bits, it's no longer worth keeping the two
halves of the qt_cpu_features variable mostly similar to the main two
CPUID results. This commit goes back to keeping things in order, like we
used to prior to commit 6a8251a89b (Qt 5.6)

At the time of this commit, GCC 8 has macros for AVX512VPOPCNTDQ,
AVX512_4NNIW, AVX512_4FMAPS, AVX512VBMI2 and GFNI.

a09fc184ac Add a configure-time check for QT_COMPILER_SUPPORTS_SIMD_ALWAYS
This has two main benefits:
 1) introduces a qmake CONFIG we can use in .pro/.pri/.prf files
 2) removes the need to keep an up-to-date list of which compilers
    support the feature

The test is implemented as trying to compile every single SIMD test we
currently have, but without passing the -mXXX option. The reason for
trying all of them is that some people may have modified their mkspecs
to add -mXXX options or -march=XXX, which could enable the particular
feature we tried, resulting in a false positive outcome.

ff1ffa7577 Add support for AVX-512 intrinsics found in MSVC 2017 15.3
It seems the compiler supports /arch:AVX512 and /arch:AVX512F but none
of the other switches (and neither are documented). And when you pass
those, you also get Conflict Detection (CD), Double & Quad (DQ), Byte &
Word (BW) and Vector Length (VL), which matches the ICC switch
"-xCORE-AVX512". Unlike ICC, there doesn't seem to be an option to
enable only the common part of AVX-512.

Support for Intel Xeon Phi's current features (Exponential &
Reciprocation and Prefetch) and future ones (IFMA, VBMI, 4FMAPS, 4VNNI
and VPOPCNTDQ) seems to be missing altogether.

unlikely a system would have futimesat and not futimes.

f54f7d8470 configure: Add a feature to write tests in the .json file
We're adding a lot of unnecessary files that end up later as cargo-cult,
for at most a handful of lines. So instead move the testcases directly
into the .json file.

The following sources were not inlined, because multiple tests share
them, and the inlining infra does not support that (yet):
- avx512
- openssl
- gnu-libiconv/sun-libiconv (there is also a command line option to
  select the exact variant, which makes it hard/impossible to properly
  coalesce the library sources)

The following sources were not inlined because of "complications":
- verifyspec contains a lengthy function in the project file
- stl contains lots of code in the source file
- xlocalescanprint includes a private header from the source tree via a
  relative path, which we can't do, as the test's physical location is
  variable.
- corewlan uses objective c++, which the inline system doesn't support

reduce_relocs and reduce_exports now create libraries with main(), which
is weird enough, but doesn't hurt.

c3cd0f6e19 configure: Remove test for unused feature "mremap"
It's a Linux-specific call that was added to the kernel in pre
historical times (before Git). Sqlite3 uses mremap(2) but it has its own
checking. Nothing else in Qt uses this.

Looks like the last user was the QPF font engine, removed in commit
d7e424ee66 almost four years ago. And
that's considering that the QPF font engine wasn't in use since Qt 5.0
because QWS was no more...

cfbe03a6e0 QSslSocket: OpenSSL 1.1 backend
This patch-set implements a new QSslSocket backend based on OpenSSL 1.1.

1. General.

The code in this patch was organized to achieve these (somewhat contradicting)
objectives:
- keep the new code free of #if-ery, as far as possible;
- make it easy to clean away dead code when we're eventually able to retire
  out-dated OpenSSL versions;
- reduce the amount of code duplication.

If changes in some file/component were insignificant (~5 one-liners per file),
we still use pp-checks like: #if QT_CONFIG(opensslv11) ... #else ... #endif -
the logic is simple and it's still easy to clean the code if we remove the legacy
back-end. Where it saved #if-ery, we also introduced 'forward-compatible'
macros implementing equivalents of 1.1 functions using older OpenSSL.

In case some class contains a lot of version-specific ifdefs (particularly where
nested #if-ery was complex) we choose to split code into: "pre11" h/cpp files,
"shared" h/cpp files (they preserve their original names, e.g qsslsocket_openssl.cpp)
and "11" h/cpp files. If in future we remove the legacy back-end, "pre11" should be
removed; "shared" and "11" parts - merged.

2. Configuration.

We introduced a new feature 'opensslv11' which complements the pre-existing
'openssl' and 'openssl-linked' features. The 'opensslv11' feature is enabled
by a simple test which either compiles successfully or ends in a compilation
error, depending on a value of the OPENSSL_VERSION_NUMBER constant. If the
feature was enabled, we also append an additional compilation flag
-DOPENSSL_API_COMPAT=0x10100000L to make sure our new code does not contain
deprecated structures, function calls, macro-invocations from OpenSSL < 1.1.

120ecc976f QRandomGenerator: use getentropy on Linux & OpenBSD
The getentropy function, first found in OpenBSD, is present in glibc
since version 2.25 and Bionic since Android 6.0 and NDK r11. It uses the
Linux 3.17 getrandom system call. Unlike glibc's getrandom() wrapper,
the glibc implementation of getentropy() function is not a POSIX thread
cancellation point, so we prefer to use that even though we have to
break the reading into 256-byte blocks.

The big advantage is that these functions work even in the absence of a
/dev/urandom device node, in addition to a few cycles shaved off by not
having to open a file descriptor and close it at exit. What's more, the
glibc implementation blocks until entropy is available on early boot, so
we don't have to worry about a failure mode. The Bionic implementation
will fall back by itself to /dev/urandom and, failing that, gathering
entropy from elsewhere in the system in a way it cannot fail either.

uClibc has a wrapper to getrandom(2) but no getentropy(3). MUSL has
neither.

078f04254e Add support for OpenGL ES 3.2 in QOpenGLExtraFunctions
Follow the usual pattern:

Add a config test and automatic include of GLES3/gl32.h if there
is a GLES 3.2 capable header+lib at build time.

Then, regardless of this being enabled, expose all new 3.2 API
functions in QOpenGLExtraFunctions and resolve them dynamically
at run time.

This way 3.2 functions will be available when deployed to a 3.2
capable system (or OpenGL 3/4.x with the functions in question
available) regardless of what was present in the sysroot at build
time.

0669f71b0c QRandomGenerator: don't internally rely on QT_HAS_INCLUDE
GCC didn't support it until version 5 or 6, so add configure tests for
both <random> and <sys/auxv.h>. Normally I'd say "upgrade", but this is
too low-level and important a feature.

There's a good chance that all our supported compilers have <random>
anyway. As for <sys/auxv.h>, it's present on Glibc, Bionic and MUSL, but
I don't see it in uClibc (AT_RANDOM is a Linux-specific feature).

d0706ae3a3 Enable stack-protector-strong for QNX 7.0.0
This was originally enabled in the mkspecs for 64-bit QNX 7.0.0
but that broke when the qtConfig change was made.  It looks like
qtConfig shouldn't be used in the platform mkspecs.  I suspect
the stack-protector changes were left out of the 32-bit mkspecs
so that 6.6.0 builds wouldn't be affected.

Ignore the stack-protector/stack-protector-all possibility since
it isn't possible to access it without a command line option.
Specifying both options doesn't even make sense since
stack-protector-all encompasses stack-protector.

For now, leave out command line control of this feature.
