Instead of detaching when the string is shared, or if the the insertion
would cause a reallocation, create a new string and copy characters to
it as needed, then swap it with "this" string. This is more efficient
than detaching which would copy the whole string before inserting, as
some characters would be copied multiple times.
Use detachAndGrow(), otherwise QStringBuilder unitests fail:
PASS : tst_QStringBuilder1::initTestCase()
FAIL! : tst_QStringBuilder1::scenario() 'prepends < max_prepends' returned FALSE. ()
Loc: [tests/auto/corelib/text/qstringbuilder/qstringbuilder1/stringbuilder.cpp(61)]
PASS : tst_QStringBuilder1::cleanupTestCase()
The issue is that now when inserting, if the string is going to
reallocated, we create a new string, so the freeSpaceAtBegin()
optimization doesn't work the same way.
void checkItWorksWithFreeSpaceAtBegin(const String &chunk, const Separator &separator)
{
// GIVEN: a String with freeSpaceAtBegin() and less than chunk.size() freeSpaceAtEnd()
String str;
int prepends = 0;
const int max_prepends = 10;
while (str.data_ptr().freeSpaceAtBegin() < chunk.size() && prepends++ < max_prepends)
str.prepend(chunk);
QVERIFY(prepends < max_prepends);
...
...
each str.prepend() would have reallocated.

If the object is shared, instead of detaching, copy characters from
"this" to a new object except for the chacters that would be erased,
this is more efficient than detaching (which would copy the whole data
then erase).
- Extend tst_QString::removeIf() to catch a corner-case (that I saw
with tst_QByteArray::removeIf()).
- Add q_uninitialized_remove_copy_if, which works like
std::remove_copy_if but for uninitialized memory like
q_uninitialized_relocate_n (but copies rather than relocates/moves).
With the same static_assert from q_relocate_overlap_n that the type
destructor is non-throwing.
Added q_uninitialized_remove_copy_if in this commit rather than a
separate one so that it's unittested by its usage in eraseIf().

Once qt6_generate_deploy_script (called by

finalized. However, qt6_generate_deploy_script needs to run before
finalization, because:
- qt6_generate_deploy_script marks the target as to be deployed
- the finalizer generates plugins information only if the target was

This fixes a use-after-free in QPropertyDelayedNotifications::notify.
Before this patch, evaluateBindings or a notify from a property index
might have caused the originalBindingData to become reallocated.
However, at that point, we've already restored the original bindingData
in evaluateBindings, so we won't track updates, and thus won't adjust
originalBindingStatus, which will then point to already freed data.
To remedy this, we no longer do the notification with data fetched from
originalBindingData, but instead use the information we have in the
proxyData.
We also need to enure that referenced bindings do not get deleted; for
that we keep the PendingBindingObserverList alive for the whole duration
of the endPropertyUpdateGroup.
As we now have the PendingBindingObserverList, we use it for the
notification logic, and only notify change handlers in
QPropertyDelayedNotifications::notify. That will allow a follow-up
cleanup of QPropertyObserverPointer::notify, and aligns the logic for
grouped updates with the logic for "nornal", non-grouped updates.

When the main executable is built with a pre-macOS 11 SDK, the macOS
kernel and system libraries will enable a compatibility mode for
reporting the system version, reporting 10.16 instead of 11/12/13 etc.
This happens at at such a low level that even manually reading the
version from /System/Library/CoreServices/SystemVersion.plist is
intercepted.
Working around this by temporarily setting the SYSTEM_VERSION_COMPAT
environment variable is unfortunately not possible, as it's only read
on process creation/initialization.
The same goes for the kern.system_version_compat sysctl, as once it's
set it can not be changed back to its original value, and it's not
clear whether this sysctl should even be touched.
As long as we have no reliable way of reading the actual current
operating system version, we need to bail out of the deployment
target verification, to avoid false negatives where a plugin or
library, built with a deployment target of say 11.0, is loaded
into an application built with a pre-11.0 SDK, but running on
macOS 11+.
