Such mappings are ill-defined in the presence of daylight-savings time
(DST); at its transitions, you need information about whether DST is
active or not to determine the correct UTC value. Existing code did
not have a way to be told that hint, so could not be correct.
Fixing this required changing the (thankfully private) APIs by which
QDateTime accessed QTimeZone's information stipulated by zone time.
In QDateTime, this required propagating the needed hint, when DST
status was known.
QAndroidTimeZonePrivate overloaded QTimeZonePrivate::dataForLocalTime
with an implementation that works whenever !hasTransitions(); the base
implementation handled this case lamely, so I've moved the Android
implementation there, to have only one place for both re-writes.
Amended tst_QDateTime's expected failures; passing a date and time to
the constructor *is* ambiguous when the moment indicated is in a
transition. I have changed which way we resolve that ambiguity.
Added round-trip test of QDateTime's fromMSecs/toMSecs (but as a
QTimeZone test, since that's what's actually getting tested), based on
a test-case from Marko Kangas. Initially failed for various zones,
each at one hour-offset; and, on some platforms, for some zones, at
all offsets. These last revealed that a platform may claim to have
zone information yet, for some zones, lack it (or have very incomplete
information). In each case, despite this, the platform does give
offsetFromUtc(). (The test also found another pre-existing bug on
Linux; fixed in an earlier commit.)
To accommodate these gaps in transition data, the transition-based
code now falls back to the offsetFromUtc()-based code (used when there
are no transitions) if it can't find a previous transition (which, in
any case, it needs to do its job).

EcmaScript mandates that number-to-string functions pad the resulting

supports this, under the disguise of the "Alternate" flag, used by
QString::asprintf().
We split this flag into the three options it actually represents and
make IncludeTrailingZeroesAfterDot available as a NumberOption. This
allows us to generate numbers in an EcmaScript compliant way.
In addition, a symmetrical option to reject trailing zeroes when
parsing strings to numbers is added.

This function reallocates a QArrayData block with realloc() but, as
the name says, it's only valid for types that do not increase the
alignment requirements. I don't think it's worth doing this for types
that do increase the alignment requirements, since we don't know the
alignment of the pointer returned by realloc(). If the new pointer
modulo the alignment is different from the old pointer modulo the
alignment, we'd have to memmove data around, which would be quite
inefficient (realloc might have memcpy'ed already and this memmove
would copy data to nearby).
This function is intended to be used especially in QString and
QByteArray, which were already using realloc() on pointers created by
QArrayData::allocate.

The hash function is carefully designed to give the same result
as the straight-forward implementation of qHash(unordered_map),
which we'll probably add at some point, namely: std::accumulate
over a container of std::pair.
This is one reason to use std:: and not QPair in the implemen-
tation of qHash(QHash). The other is that qHash(QPair) uses a
bad hash combiner, which may xor out the 'seed' from the result.
We can't fix that until Qt 6, but the qHash(std::pair) overload
uses the well-known boost::hash_combine algorithm (implemented
in Qt as QtPrivate::QHashCombine), so we can use that.
I also trust std::pair to work without problems with reference
template arguments, while QPair only very recently gained a very
basic auto-test for reference parameters.

When replacing each copy of one text with a copy of another, we do so
in batches of 1024; if we get more than one batch, we need to keep a
copy of the sought text and replacement if they're part of the string
we're modifying, for use in later batches.
Also do the replacements in full batches of 1024, not 1023 (which left
the last entry in an array unused); marked some related tests as
(un)likely; and move some repeated code out into a pair of little
local functions to save duplcation.
Those new functions can also serve replace_helper(); and it can shed a
const_cast and some conditioning of free() by using them the same way
replace() now does. (There was also one place it still used the raw
after, rather than the replacement copy; which could have produced
errors if memcpy were to exercise its right to assume no overlap in
arrays. This error is what prompted me to notice all of the above.)
Added tests. The last error proved untestable as my memcpy is in fact
as fussy as memmove. The first two tests added were attempts to get a
failure out of it. The third did get a failure, but also tripped over
the problem in replace() itself. Added to an existing test function
and renamed it to generally cover extra tests for replace.
