We have a problem. Our types don't play well with the std unordered
containers, because they do not specialize std::hash. We therefore
force our users to come up with an implementation, hindering
interoperability, since any two developers are unlikely to come up
with compatible implementations. So combining libraries written by
different developers will result in ODR violations.
Now that we depend on C++11, and thus the presence of std::hash, we
still face the problem that the standard does not provide us with a
means to compose new hash functions out of old ones. In particular, we
cannot, yet, depend on C++17's std::hash<std::string_view> to
implement std::hash<QByteArray>, say. There's also no std::hash for
std::tuple, which would allow easy composition by using std::tie().
So piggy-back on the work we have done over the years on qHash()
functions, and implement the std::hash specializations for Qt types
using the existing qHash() functions, with a twist: The standard
allows implementations to provide means against predictable hash
values. Qt has this, too, but the seed is managed by the container and
passed to the qHash() function as a separate argument. The standard
does not have this explicit seed, so any protection must be implicit
in the normal use of std::hash.
To reap whatever protection that std library has on offer, if any, we
calculate a seed value by hashing int(0). This will be subject to
constant folding if there's no actual seed, but will produce a value
dependent on the seed if there is one.
Add some tests.
A question that remains is how to document the specialization. Can we
have a \stdhashable QDoc macro that does everything for us?

Includes a fixup for 03fadc26e7, which
removed the check on empty transition list, needed when no data are
available. Ensured that such a data-free zone would in fact be
noticed as invalid during init().
Fixed handling of times before the epoch (we still want to consult a
POSIX rule, if that's all that's available) while ensuring we (as
documented) ignore DST for such times.
Fixed handling of large times (milliseconds since epoch outside int
range) when looking up POSIX rules. Gave QTimeZonePrivate a YearRange
enum (to be moved to QTimeZone once this merges up to dev) so as to
eliminate a magic number (and avoid adding another). Moved
year-munging in POSIX rules after the one early return, which doesn't
need the year range.

offsets; SLES has a minimal version of the UTC data-file that triggers

A string can parse as a non-zero double that's smaller than the

So rather than testing for non-zero doubles less than the smallest
float, test for non-zero doubles that cast to float zero; these
underflow. This means small values close below the smallest float
shall round up to it, rather than down to zero, requiring a tweak to
an existing test. Added a test for the boundary case (and tidied the

The TZ environment variable can validly contain a POSIX rule, rather
than an IANA ID, as described here:
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08_03
However, if TZ were set to such a value, leading to it being used as
systemTimeZoneId(), it would be passed to QTzTimeZonePrivate::init(),
which is a no-op unless it manages to open a zoneinfo/ file with the
given ianaId as name. When the environment variable doesn't name a
zoneinfo/ file, we would thus get an invalid time-zone. We can,
instead, check whether the ianaId looks like a valid POSIX rule and,
if it does, use it as m_posixRule, enabling us to correctly handle
this case.
Tweak parsing of POSIX rules so that a zone using name "UTC" or "GMT"
with an offset other than 0 will be rejected as invalid. This avoids
parsing a zone name such as "GMT+17" or "UTC+00:01" as a POSIX rule,
where it should be understood as an offset from UTC (and only certain
well-established offsets are supported).
Added two test-cases to tst_QTimeZone::tzTest() for validity of a
POSIX zone value - a simple one constructed during discussion of the
bug, the other taken from an example in:

Something nice we'd like to detect for array-backed containers
is if the iterator passed is a Contiguous one; if the type is also
trivially copyable / Q_PRIMITIVE_TYPE, we could memcpy() the whole

However, there's no trait in the Standard to detect contiguous
iterators (the best approximation would be detecting if the iterator
is actually a pointer). Also, it's probably not smart to do the work
now for QVector since QVector needs refactoring anyhow, and this work
will be lost.
