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.

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".

79f62380f0 QAbstractItemView: Fix IM input starting edit session
Item views can open an editor widget on the first key press, and need to
take special care not to break input methods. The initial key press
starts compositing by the system input method, which is then interrupted
by the focus transfer to the editor.

To solve this problem, the widget needs to keep focus while the initial
composition is ongoing, and only transfer focus to the editor once the
composition is either accepted or cancelled by the user. Add a state flag
that is set during this initial preedit phase.

During this initial composition, the item view will receive all input
method events, and needs to forward these to the open, but not yet focused
editor for the user to get the correct visual feedback during the preedit
phase. The item view also needs to report to input method queries on
behalf of the editor to make sure that the IM UI is correctly positioned
without covering the user input.

Implement a test that simulates the sequences through synthesized
QInputMethodEvents; we can't simulate the entire system input stack.

Decouple the newParent state from the wasCreated flag. In most places
where newParent was tested, wasCreated was either tested previously and
can't be false anyway, or the code executed is irrelevant for widgets
that are not yet created (there can't be a paint manager). In the
remaining case, test wasCreated explicitly to maintain existing logic.

57960ab075 Q{Elf,Mach}Parser: simplify the return codes
The multi-state return code was a legacy of how Arvid wrote the ELF
parser code back in the day, the fact that it scanned for two different
types of plugins in Qt 4 and that the metadata could exist in different
places.  None of that matters nowadays: who cares if the file is a
corrupt binary, not a valid binary, does not have the right
architecture, or has no suitable section? It's not a plugin, period.

The Qt 4 plugin mechanism was removed for Qt 5.0 in commit
7443895857 ("Remove support for Qt 4 style
plugins").

a5e5943d8a macOS: send enter/leave when a window opens/closes
Since macOS doesn't give us any event when a modal window opens,
we need to do so ourselves explicitly so that the current mouse
window gets a leave event when e.g. a popup opens, and an enter
event when the popup closes again. The case for modal dialogs is
partially handled by QGuiApplication already.

Note: We cannot rely on the transientParent of the opening/closing
window, as it's nullptr for QMenu windows even if the QMenu has
a widget parent.

Add a test for enter/leave events when a secondary window opens,
covering both the dialog and the popup case. For the dialog case,
we sometimes get two Enter events when the dailog closes, which
we have to tolerate for now.
To make the test pass on b2qt platforms, fix the offscreen plugin
to explicitly send enter/leave events in the same way as Cocoa
now does.

3714e51436 QWidgetWindow: Stabilize test on Xcb
Showing, hiding, and showing a window can result in the Xcb QPA plugin
warning about

qt.qpa.xcb: internal error:  void QXcbWindow::setNetWmStateOnUnmappedWindow()
called on mapped window

The point of the test is to verify that we get a paint event on a window
that is shown again after having been hidden, not to verify that async
windowing systems can handle a show/hide/show sequence. So wait for the
window being exposed before we hide it.

7943480f0f Fix QDateTimeParser's handling of 't' format to match serialization
This amends commit 68f19fb630 to only
consume one 't' from the format string, to match qlocale.cpp's
serialization of time-zone specifiers, which only consumes one, so
will repeat the time-zone specifier as many times as unquoted t
appears in the format. It's hard to imagine why anyone would want this
behavior, but it's what our serialization has always done and parsing
should match serialization.

Add test-cases for double time-zone specifier.
Delete a lie in the process.

b4bb3a5415 Introduce QDoubleValidator::setRange overload with two parameters
The QDoubleValidator::setRange() used to have 3 parameters, with
the third one (the number of decimals) having a default value of 0.
Such default value does not make much sense for a *double* validator.
Also, since a default value was used, omitting the decimals was
silently overwriting the previous decimals value, discarding the
value that could be previously explicitly specified by user.

[ChangeLog][QtCore][QDoubleValidator][Important Behavior Changes] The
QDoubleValidator::setRange() method now has two overloads.
The first overload takes 3 parameters, but does not support a
default value for decimals.
The second overload takes only two parameters, not changing the
number of decimals at all.
Hence, the number of decimals will only be changed if the user
explicitly specifies it.
To maintain the old behavior of setRange(), pass 0 as the 3rd
argument explicitly.

Note that it is a source-incompatible change. But it should be fine,
because using QDoubleValidator with 0 digits after decimal point does
not make much sense and so, hopefully, is not that common.

At the same time, change the default-constructed QDoubleValidator
to use -1 for decimals, which allows arbitrarily many digits in
the fractional part. The value was previously 1000, which allowed
more than anyone would reasonably use, so this should make no
practical difference.

Some more unit tests to cover the behavior of the setRange()
overloads are also added.

As a dirve-by: remove unnecessary QValidator::State to int conversions
in the unit tests. QCOMPARE is capable of comparing these enums and
provides a better output in case of failure for enums.

In a blocking application, receiving the results of write operations
must be synchronized with the waitFor...() functions. But, clearing

to fail unexpectedly, if the socket has been disconnected between
the calls.

So, defer resetting the buffer until checkForWrite() is called.
