There's little need for us to dynamically load it. The reasons why that
was necessary aren't in the public history (Qt 4.5 already had it[1]). I
remember writing the code in 2007-2008, I just don't remember why.
On modern Linux and FreeBSD, there's no libresolv.so any more and those
symbols have been rolled up into libc.so. It's still necessary on Darwin
systems, so this commit introduces WrapResolv.
It also resolves the unity build issues relating to libresolv symbols.

This simplifies the code greatly, because we don't need to use
QtPrivate::convertToMilliseconds any more, as QDeadlineTimer has
nanosecond precision.
Internally it becomes simpler too because lockInternal was already using
QDeadlineTimer. I just had to use the parameter instead and update the
two non-futex implementations to take it again. This may even be fixing
a mistake in case sem_timedwait(2) got interrupted.

This propagates inside the internals, ending up in wait_until calls in
the internal std::condition_variable. For systems with proper support
for monotonic waiting (Linux, FreeBSD), this should improve performance.
We could even remove the hasExpired() check and pass a time point in the
past too. Right now, there's a minor performance drawback for
tryLockForXxxx(), because we will make at least two system calls to get
the time.

A zone without transitions, such as any UTC-based one, would
previously return invalid data for the offset data at a given

offsetFromUtc(), abbreviation(), etc" but these methods do return
sensible data for a zone with no transitions. Furthermore, the backend
data() method on which it depends is implemented by all backends,

Fix offsetData() to also return data when no transitions are
available. Improve docs.

QTimeZone is no longer dependent on feature timezone, only its

name. So replace the zoneName column with a plain zone column, make
the UTC row for the epoch use QTimeZone::UTC instead of "UTC" and make
only the remaining rows depend on the feature, and then only for their
test using the backend zone.
The test itself was doing some convoluted twists to check local time
handled the relevant dates and times as expected. Where local time is
the zone the test relates to, this can just as well be handled by
adding a separate row for it - which we can even do without feature
timezone.
Otherwise, testing an expectation that local time *doesn't* have
anything odd going on for the selected days was somewhat unreliable,
as other zones that coincide with the tested zone for that particular
date would fail. So just drop that unreliable side of the local-time
testing.

right, of course, even though warning in a template that clearly has
instantations where it's not dead code isn't exactly helpful.
Nonetheless, take the opportinity to avoid the dead code warning at
the expense of a bit or un-DRY-ing:
- because we now use them more than once, cache the result of
is_*function_* predicates in constexpr variables
- then scope the is_null variable such that its use is not subject to
dead-code removal anymore (at instantiation time; it may still be
removed by the optimizer)
