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.

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.

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

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

- corewlan uses objective c++, which the inline system doesn't support

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.

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.

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.
