It's not a real leak in that the string data is being freed on program
exit (or, more recently, QPixmapCache::clear()), but it can lead to
lots of memory being bound for much longer than expected when users
put in new QString keys without attempting to retrive them again. It
can also lead to problems with QStringLiterals lingering around until
after their underlying data has been freed. A bug in the Fusion style,
generating new string keys for identical state, exposed this
misbehavior, and one way to fix the resulting issue for the user is to
make sure that QPixmapCache doesn't leak QString keys.
The Fusion style issue with generating non-repeating keys for use with
QPixmapCache should also be fixed, eventually, but this patch
relegates that to an optimization issue (the caching is effectively
non-existent), the resource exhaustion is gone now.
The issue exists because the QString keys are internally mapped to
QPixmapCache::Key's by way of a QHash<QString, Key> cacheKeys data
structure. When the QCache, indexed by Key, not QString, decides to
evict an entry, the Key is invalidated, but no-one was removing the
corresponding entry from cacheKeys. So make the existing releaseKey(),
used to invalidate copies of Keys referring to evicted pixmaps, do
that, now. So as not to have to scan the whole cacheKeys QHash for the
right Key, store the QString key, if any, inside the Key, so
releaseKey() can retrieve it and use it for O(1) erasure from
cacheKey.
This allows removing the previous work-around in clear()
(6ab0d25a09), greatly simplify
object(QString), and requires to rewrite all code that holds iterators
or references into cacheKeys over an insertion into or removal from
the QCache. Two (insert() and remove()) have already been done in
prequel commits, so only flushDetachedPixmaps() was left.

We would previously only use the fallback theme for themes that did
not exist, or for themes that did not declare any parent theme.
We now unconditionally use the fallback theme, even for themes that
declare their own parent themes, so that a QIcon::fromTheme("foo")
that doesn't exist in the current theme, nor any of its parents,
nor in "hicolor", will still be looked up in the fallback theme.
The reason this seemed to work in the existing tests was because
our test themes inherit system themes such as crystalsvg and gnome,
and we didn't provide a hicolor theme. Any of these themes missing
would lead us into the code path where we use the fallback theme
for a missing theme, masking that fact that we had not added the
fallback theme to the list of fallbacks for the theme that had
explicit parents declared.
The logic has been moved out of the theme parsing and into an
accessor in QIconTheme, so that we're not caching the fallback
theme lookup.

The replace() implementation overwrites the passed Key key with a new

const.
Deprecate the function.
Also inline the const_cast, so compilers can readily detect the UB
even if users don't enable deprecation warnings. Due to the severity
of the issue (UB), immediate deprecation is warranted. There appear to
be no in-tree user of the API outside of tst_qpixmapcache.cpp.

Between the find() == 0 obfuscation (since fixed) and this unchecked
replace(), it took me way too much time to figure out what was going
on: the key passed has been invalidated by the setCacheLimit(0).
Now that we QVERIFY that the replace() _fails_, it's much easier to
backtrack and figure out why it does so and why, consequently, the
following find() is also expected to fail.
As a drive-by, reorder two lines so the grouping becomes clearer

QPixmapCache maintains a mapping from QString to QPixmapCache::Key, in

Since setScaledClipRect will actually render only the necessary parts,
there may be insignificant differences in rounding/anitaliasing
compared to rendering the whole image first and then clipping.
Hence this autotest case would always fail. But that would not happen
in CI, since it tests qtbase without the qtsvg module, and then the
SVG tests are skipped. (For some reason, one ran into this in wayland
testing and made an exception for that, but obviously this failure has
nothing to do with wayland).
Work around the issue by converting the rendered images to 4 bpc
format, so the differences in the least significant bits get truncated
away.
