QMutableListIterator::remove() is linear, so called in a loop, the
loop potentially becomes quadratic.
Fix by porting to std::remove_if. In this case, since the old code
unconditionally detached, anyway, we use remove_copy_if to build a new
list. That's still more efficient than the old code, even if nothing
is removed. It also prepares the code for when Java-style iterators
will be deprecated.
Since the same code appears in two different functions, do an Extract
Method into a file-static function.
Lastly, restore NRVO for most compilers by returning the same object
from all return statements of the function.

Java-style iterators are scheduled to be deprecated.
The general pattern used in the patch is that instead of copying an
input list, then iterating over the copy with some calls to
it.remove() (which leads to quadratic-complexity loops), we simply
copy conditionally (a la remove_copy_if instead of remove_if).
To make clearer what's going on, rename the outgoing list to
'unhandled'.
To avoid having to touch too much of the loops' structure, which
sometimes is quite convoluted, use qScopeGuard to do the append to
'unhandled', unless the original code removed the element.
Saves a surprising almost 5KiB in text size on GCC 9.1 optimized
AMD64 Linux builds.

The original is much more subtle, so don't try to be a 100%
replacement. Most users will be able to use std::make_unique these
days. This is just a minimal implementation to enable using the
functionality in the implementation of Qt libraries. In particular,
it does not attempt to deal with arrays.
It is therefore not proposed as public API. It is placed in a new
private header, since the only header in QtCore that already
includes <memory> is sharedpointer_impl.h, and that did not seem
to be a good place to add it. It is probably too much of a
compilation-time drain to add <memory> to qglobal.h...

The whole reason of QCharRef/QByteRef existence is to have a magic
operator=. This operator= delays the actual detach up to
the moment something is written into the Ref, thus avoiding
spurious detaches to the underlying string/byte array.
operator= has also an extra feature, it allows this code to
succeed:
QString s("abc");
s[10] = 'z';
assert(s == "abc z");
This last behavior is *extremely* surprising.
The problem with all of this is that this extra convenience is
outweighted by the massive pessimization in the codegen for
operator[]; by the maintenance burden (QChar APIs need to be
mirrored in QCharRef, etc.), and, for the automatic resize, by the
fact that it's an super-niche use case.
Cherry on top, std::basic_string does not do that, and no Qt or std
container does that. In other words: any other container-like class
exhibits UB for out of bounds access.
We can't just go and change behavior, though. This is something
coming all the way back from Qt 2 (maybe even Qt 1), which means we
can't deprecate it at short notice.
This patch simply adds a warning in debug builds in case the special
resizing behavior is triggered. While at it, removes some code
duplication in QByteRef.
[ChangeLog][QtCore][QString] The behavior of operator[] to allow
implicit resizing of the string has been deprecated, and will be

[ChangeLog][QtCore][QByteArray] The behavior of operator[] to allow

The code contained a sizeable chunk of string parsing along with
qDebug()s in the normal path of execution. That code, however, was
only used for Qt's own autotests.
The idea of this patch is, then, to not only move the autotest case
into the cold text section (using Q_UNLIKELY), but also to completely
exclude it, when QT_BUILD_INTERNAL is not set.
Unfortunately, the structure of the function did not really lend
itself to #ifdefing that part of the code out (production code was in
the middle of non-production code), so I transformed the engine
selection code into a lambda, replacing assignment with returns, and
swapping the branches of the central if around to yield a single block
of code that can be excluded from compilation with just one #ifdef.
As a consequence, the runtime code is almost unaffected, and the
function is much easier to read now.
Since the test-specific code is only compiled into Qt now in developer
builds, guard the tests that rely on this behavior with the same macro.

This saves one move construction and doesn't produce unexpected

Information about header files is cached by qmake. The key is the
filename of the #include directive. For system includes (<stdio.h>) this
is unique, according to the search order in INCLUDE_PATH.
For local includes, given as "foo.h", there may be name collisions. Usually a
compiler first searches in the directory of the current file (stored in the
sourceDir variable), and only in case of a miss the INCLUDE_PATH is
considered.
The dependency generation now distinguishes local header files by their full
relative path. This is implemented by forcing the use of the full relative
path as key into the SourceFiles data structure if the flag try_local is set.
