When parsing a date-time's zone, a stray Z denotes UTC (a.k.a. Zulu
time), despite not being a valid name for the zone. Clients parsing
such date strings had to treat the Z as a literal, rather than a
zone-ID, but then they got back a LocalTime instead of the UTC the
string actually described. So teach QTimeZoneParser to handle this
special case and adapt an existing test (that used a time ending in Z,
but had to treat it as a local time) to check this works.
[ChangeLog][QtCore][QDateTime] When parsing a time-zone, "Z" is now
recognized as an alias for UTC.

Actually check that there's a T where ISO 8601 wants it (instead of
just skipping over whatever's there), with something after it; move
some declarations later; add some comments; and use the QStringRef API
more cleanly (so that it's easier to see what's going on). Simplify a
loop condition to avoid the need for a post-loop fix-up.
This incidentally prevents an assertion failure (which brought the
mess to my attention) parsing a short string as an ISO date-time; if
there's a T with nothing after it, we won't try to read at index -1 in
the following text. (The actual fail seen had a Z where the T should
have been, with nothing after it.)
Add tests for invalid ISOdate cases that triggered the assertion.

Unlike setTimeSpec, this forgot to clear the bit when detaching. So it's
possible that some further use of the flags could incorrectly conclude
that the data was short and then proceed to corrupt the pointer.
The example from QTBUG-59061 caused this because toUTC() -> toTimeSpec()
calls setMSecsSinceEpoch which left the bit set; then addDays() calls
setDateTime(), which calls checkValidDateTime() and that corrupted the
pointer. This problem was more visible on 32-bit systems because no
QDateTime was short (except for default constructed ones), but it
can happen on 64-bit with sufficiently large dates.

Some format and parse tests for time and date-time depended on locale
but had test data for the C locale (so fail if the test-environment
has, e.g., LANG=de_DE@utf8). So impose the C locale (until Qt 6).
The date-time test did *some* attempts at fixing for locale, but
failed to handle am/pm; and we do have "### Qt 6" comments in
Q(Date|Time)+::fromString indicating that we intend to switch these
methods to use the C locale by default (which shall fix this once and
for all). So rip out the incomplete localization now and test we work
properly at least when the locale used *is* C. Add a comment to the
matching QDate test to rip out its (presently adequate) matching code
once we do get to Qt 6 and make fromString() use the C locale.
QDateTimeParser uses systemLocale(), which is initialized the first
time it gets accessed; so we need to frob the locale *early*; doing so
in the test-class constructor is about as early as we conveniently
can; and seems to work (while doing it in individual tests does not).
(There is no point rolling back at the end; the QSystemLocale global
has been set up by then, so the roll-back would merely leave the
global out of sync with setlocale() and the environment.)

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).

ignorant of its DST, while a .toLocalTime() one knows its DST.
