Use optimize("Os") (available since GCC 4.4¹) or minsize (Clang²),
using __has_attribute() to switch between them. Both don't mark the
function as [[unlikely]] and don't co-locate it with other cold
functions (like error handling or exception tables).

Android a11y: announce text edits so screen readers echo typing

With a screen reader enabled, typing or deleting characters in a Qt text
field produced no spoken feedback, and the field's label was not announced
— making edit controls very hard to use.

Several gaps caused this:

- Qt Quick text items emit a QAccessible text-change event only from the
  programmatic setText() path, never from input-method or key-event edits,
  so nothing reached the Android accessibility bridge while typing.
  Generate the events at the platform chokepoints instead:
  QAndroidInputContext::endBatchEdit() announces IME edits (with mid-batch
  changes deferred via a pending flag so unmarked mutations such as
  finishComposingText()'s commit are covered), and update() announces edits
  that bypass the IME entirely (KEYCODE_DEL backspace, hardware keys,
  programmatic changes). The changed span is a prefix/suffix diff of the
  field text, kept on code-point boundaries. Announcing only from these
  chokepoints (not also from the QAccessible::TextInserted/Removed/Updated
  path) avoids double-announcing programmatic changes, which update()
  reports too.

- QtAccessibilityDelegate.notifyTextChanged() fires the two events a real
  editable view fires on each keystroke, sourced from the input-focused
  node: TYPE_VIEW_TEXT_CHANGED (what changed) and a companion
  TYPE_VIEW_TEXT_SELECTION_CHANGED (the new caret position). The selection
  event matters because a screen reader echoes typing from the input-focused
  editable; the text-changed event alone is not honored when accessibility
  focus is on the soft keyboard rather than the field.

- Editable nodes exposed their content only via setContentDescription().
  A screen reader reads an editable's text to track the caret and echo
  edits, and reads its label from the hint; with neither set the field was
  treated as empty and unlabeled. populateNode() now also sets text,
  inputType (TYPE_CLASS_TEXT) and hintText (the accessible name) for
  editable nodes.

Confirmed on a Samsung Galaxy Tab A9 (Android 16) by a blind user: with the
single text-changed event, a screen-reader update stopped speaking it during
typing (its source is not the accessibility-focused node while the keyboard
is open); adding the caret/selection companion — matching how a standard
editable view drives typing echo — restored spoken feedback for typing and
deletion.

CMake: Disable '-Wgnu-include-next' for Apple header checks

Starting with Xcode 26, `-pedantic-errors` enables
`-Wgnu-include-next` which causes errors in framework forwarding
headers that use `#include_next` during a headers clean check.

Disable the warning in the header check, specifically when using
Apple Clang from Xcode 26 or later for a Qt framework build.

QMatrix4x4: deduplicate code between two ctors

The QGenericMatrix<N,M,float> ctor was performing exactly the same
operations as the (const float *, int cols, int rows) one, except the
former is inline and the latter is out-of-line.

While an inline function is more likely to be optimized properly,
incl. strength-reducing the multiplication in the inner loop, we can
do these optimizations to the out-of-line function manually, and
reduce code duplication (both source and executable) with very little
performance overhead. There's only one in-tree user of this contructor
(from QMatrix3x3), so I think the advantages outweight the
disadvantages here.

Amends the start of the public history, which, of course, didn't have
constructor delegation available, as this was a C++11 addition.

CUPS print dialog: Support entering custom values for PPD options

CUPS not only supports PPD options that have a fixed
set of values to choose from, but also PPD options
that allow entering a custom value.

CUPS documentation on custom options: [1]

Implement support for such custom PPD options by
adding a QLineEdit to enter custom text when a non-null
return value of ppdFindCustomOption [2] indicates that
a custom option exists.

Show that one only if the "Custom" value has been
selected for the PPD option. In that case, set
manually entered value in the print options
in QPrintPropertiesDialog::setPrinterAdvancedCupsOptions
as "Custom.<entered_value>" which matches the behavior
passed of other CUPS client application implementations
like GTK 3 applications or LibreOffice.

This commit implements passing a value manually entered
in the Qt print dialog to the CUPS print job.

So far, responsibility that the user-entered text
meets the type and minimum/maximum length supported
for the custom option is fully on the user, i.e.
the value is simply passed to CUPS as is.

QDirEntryInfo: assert the variant is not valueless_by_exception

Coverity keeps complaining about the std::visit()s in this class
potentially throwing std::bad_variant_access, even after we closed the
one real source of valueless_by_exception() (never realized in
practice) by giving QFileInfo a nothrow move constructor
(cf. eb4b67478a1a36c476ad20a90e7d5a3fd080516c).

Next try is to add asserts, which this patch provides. If this also
fails, we need to port away from std::visit and switch over index()
instead. This is causing way too much fallout to not do anything about
it.

Amends 336ff06b648e2e7419f9234e4d1018a63ac9fb5b (picked to 6.11).

Since even QFileInfo copy wouldn't throw in practice, we can pick this
to 6.11, it doesn't hinge on a nothrow-move-constructible QFileInfo.
