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...

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.

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.

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).

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.

PCRE1 is going towards EOL. PCRE2 is the way forward in terms
of new features, performance, and security improvements. The
APIs that QRegularExpression uses are similar so the required
modifications aren't extensive.
The biggest difference comes to JIT-compiling of the pattern.
In PCRE1, JIT-compiling did not modify the processed PCRE pattern,
but returned a new chunk of data.
This allowed multiple threads to keep matching using the same
processed data and NULL for the JIT data, until a thread
JIT-compiled and atomically set the shared JIT data to the results
of the compilation.
In PCRE2, JIT-compiling _modifies_ the processed PCRE pattern in a
way that it's thread unsafe [1]; the results of JIT-compilation
are stored somewhere inside the processed pattern.
This means the above approach cannot work -- a thread may be
matching while another one JIT-compiles, causing a data race.
While waiting for better workarounds from upstream, employ a
read/write mutex to protect the matching from JIT-compilation.

[ChangeLog][General] QRegularExpression now requires the PCRE2
library, at least version 10.20. Support for the PCRE1 library
has been dropped. A copy of PCRE2 is shipped with Qt and will
automatically be used on those platforms which lack it.

This commit re-enables support for OpenVG in Qt, but not in the
same way as in Qt 4.8. The first part is about adding a test
and using the new configure system to enable OpenVG.
There is still support code in Qt for setting up EGL to provide a
surface and context for rendering with the OpenVG API, this commit
enables a path to do so.
Normally to get access to an EGLContext from a QWindow you do so via
QOpenGLContext, but in setups without OpenGL but with EGL and OpenVG
this doesn't make sense (there would be no QOpenGLContext). So the
intended way is to use a QWindow to get an EGLSurface, then create
an EGLContext directly (without going through QPA).

Recent Khronos headers decided to break the world by guarding all

been used for extension headers only.
Until this gets corrected - see
https://lists.freedesktop.org/archives/mesa-dev/2016-September/128654.html
- add the define to the config tests and qopengl.h.
While 5.7 already has some of the qopengl.h fixes due to an upgraded
ANGLE shipping with newer headers, this is a cross-platform issue that
will surface everywhere eventually. Therefore we target the full set
of fixes to 5.6.
This time we also make sure the forced define of GL_GLEXT_PROTOTYPES
is removed before including the ext header, thus apps get the ext
protos only if they actually requested them.

so far, each library was distributed over a test and (optionally) a
'library' output of a feature. this was conceptually messy and limiting.
so instead, turn libraries into a category of their own.
libraries now support multiple properly separated sources, which makes
overriding them a lot saner. sources can be conditional to accommodate
platform differences.
as an immediate consequence, move (almost) all library references from
the config test projects to the json file.
a few tests were excluded, because they are doing somewhat magic things
that should not be handled in this bulk change:
- freetype: .pri file shared with actual source code
- clock-gettime: -lrt is conditional, and there is a .pri file which is
shared with actual source code
- ipc_posix: -lrt & -lpthread conditional
- iconv: -liconv conditional
the multi-source mechanism is used to make a variety of tests work on
windows, where the library name differs from unix (and sometimes between
build configurations). some tests still needed minor adjustments to
actually work.
on the way, fix up disagreements between manually specified libraries
and pkg-config lines (affecting several xcb-related tests).
