46fc01d7ca QElfParser: rewrite using elf.h
This rewrite uses the actual structures supplied by the system's C
library, so it should be easier to read. It removes hardcoded constants
with little evident meaning in favor of sizeof() and the macros from
that header. It also removes advancing the data pointer in favor of
having absolute offsets.

The resulting implementation is stricter than the original, checking
more fields in the header. Because the QPluginLoader and QFactoryLoader
users may make decisions based on availability of plugins before
attempting to load them, it's better to be stricter here than to fail
later when trying to dlopen() them.

Debugging and testing are much improved. Instead of stored artifacts, I
added a routine to modify a valid plugin to make it invalid, given the
conditions we've found so far.

If you turn debugging on for this category, you'll see things like:

2c3617dfcb Always enable QRegularExpression's JIT when testing
Given on most CI configurations we run tests only on debug builds, this
means that effectively we don't test JIT paths (JIT is kept disabled in
debug builds). To keep it enabled in a test, we have a few options:

* export a developer-build-only variable from QtCore, to force JIT
usage, and set it in the test. This is still suboptimal as many
configurations aren't using developer builds in the first place;

* use the already existing QT_REGEXP_USE_JIT environment variable,
setting it from CMake/CTest. The problem here is that although add_test
does support it, we don't expose it through our wrapper functions;

* just set that env variable from within the test itself. I went for
this option.

b689d8dccd macOS: Disable PCRE JIT when running under Rosetta
Although the Apple docs claim that Rosetta can translate apps that
contain just-in-time (JIT) compilers, it seems to have problems with
the PCRE JIT.

https://developer.apple.com/documentation/apple-silicon/about-the-rosetta-translation-environment

To be on the safe side we disable the JIT explicitly when detecting that
we are running under Rosetta. It's already disabled when we're running
on macOS ARM natively (see 2f8df4d1a8).

165e01d5d5 CMake: Ensure that UNIX is set for INTEGRITY
Certain platform-related variables, in this case UNIX, must be set in a
platform module, because they get cleared after the toolchain file is
loaded.  Such platform modules live in upstream CMake, but there is none
yet for INTEGRITY.  This manifests in an undefined UNIX variable and
"System is unknown to CMake" warnings for the project and every
configure test.

Add the CMake module "Platform/Integrity" in the cmake/platforms
directory.  Add this directory to CMAKE_MODULE_PATH to let CMake load
Platform/Integrity when the toolchain file set CMAKE_SYSTEM_NAME to
"Integrity".

CMake's module directory takes precedence, when loading platform
modules.  This is special for platform modules and different from the
documented behavior of CMAKE_MODULE_PATH and include().

In case the user wants to provide their own platform modules via
CMAKE_MODULE_PATH, they can instruct Qt to not add its path by setting
QT_AVOID_CUSTOM_PLATFORM_MODULES to ON.

Make sure that configure tests with project files also load the custom
platform module.

0a02d84555 Add basic android multi-abi support for CMake projects
Use CMake external project to crosscompile android libraries for
mutliple android ABIs at the same time.
The idea behind is to use pre-compiled Qt for each android ABI in
external projects, compile libraries and then utilize results of
compilation in common androiddeployqt call.

By default multi-abi build uses the main ABI that qt toolchain file
belongs to. The list of the autodetected Qt for Android ABIs is stored
in QT_DEFAULT_ANDROID_ABIS cache variable. Users may change the set of
the Android ABIs project-wide using QT_ANDROID_ABIS CMake variable or
for the specific target by adding the ANDROID_ABIS argument when
calling qt6_add_executable. To enable build for the autodetected ABIs
user may set the QT_ANDROID_BUILD_ALL_ABIS option to TRUE.

By default build procedure is looking for the respective android_<abi>
folders to run per-abi build. If user's Qt for Android folder structure
is different then one is created by Qt installer, path to the each
Qt for Android might be overwritten using QT_PATH_ANDROID_ABI_<abi>
CMake variable.

Note: This only adds support for the multi-abi build of user's
applications.

TODO: This commit limits projects to not have in-tree library
dependencies. That means that executable targets may have
dependencies only from Qt directories or android sysroots.
See QTBUG-94714 for details.

[ChangeLog][Android][Platform Specific Changes] Added basic support
for multi-abi builds of user projects.

a5073956f8 QSFPM: remove redundant call to update_source_sort_column()
Everywhere else in this code, it says
  if (update_source_sort_column() && dynamic_sortfilter)
so, doing the same here.

This originally comes from commit 3ffcfc357d
but skelly isn't around anymore, and Milian (reviewer) had
no objection to this change either. Looking into the implementation,
calling it twice is a no-op anyway, create_mapping will early-return
with "already done".

On the other hand, now it has a chance of returning true, while before
it would always return false in the second call ("return true if the column was changed").
I couldn't write a unittest for that case though, it would require that
a source reset also changes the proxy->source column mapping somehow,
but I don't see how that can be done (the latter being the QSFPM setup).

If __cpp_lib_hypot is undefined in macos you may observe the error:

  error: '__cpp_lib_hypot' is not defined, evaluates to 0 [-Werror,-Wundef]

Adding the explicit check for definition suppresses the warning that

279176aa5d QPlugin: simplify handling of exact results from Q{Elf,Mach}Parser
Those two scanners always return exact results, if the metadata is
present, so we don't need to re-scan (haven't needed since Qt
5.0). Especially since we scan from the end, we were spending cycles
doing unnecessary work.

461084b6c4 Q{Elf,Mach}Parser: harmonize the arguments passed
Both functions took a QString for the input file name, but while the ELF
parser had an optional QLibrary pointer (which was never null) where to
store the error string, the Mach-O parser received a pointer to a
QString. So make both of them take a single in/out QString pointer,
which has the file name on input and is cheap for us because of COW.

Drive-by fix the name of the static function in qmachparser.cpp from
"ns" (which stood for "not suitable") to "notfound".

When we created the functionality, the levels were not yet standardized.
Now they are and you can use -march=x86-64-v3 (for example) to get to
them. We're making a split between "v1" and "baseline" here for the
benefit of 32-bit, which is not included in the ISA levels.

788a7bfdb1 QPlugin: move some of the logic from moc's output to qplugin.h
This will allow us to make changes in QtCore itself, without having to
worry about moc compatibility.

The output uses an #ifdef so this version of moc can still be used to
compile earlier versions of Qt (usually, in cross-compilation
environments). See discussion in the mailing list[1].

3a8c8e7cf6 Remove an overly-complex assertion
It tried to sanity-check the correction being made to the time as a
result of converting zone to UTC, but handling also the case where the
correction avoided a gap. However, there are too many quirky cases to
permit a simple condition. The latest to trip it up is a case of a
zone leaving local solar mean time; a time in the gap that hits is
shunted by the width of the gap, which could be any old thing, and
won't show up on the data describing the zone before or after the
transition.

In any case, one branch of the check was doubling the zone's standard
time offset, which makes no sense. As that was checking for
double-DST, it would need to check standard offset plus twice the
usual DST offset; but the data it's looking at probably has its DST
offset set to the doubled one that needs to deal with. In general a
change in DST without going via standard time will have problems here,
and a change to standard time could also present problems.

Stop trying to shore up the assert and just trust the offset we got.
