The Linux kernel gives us 16 bytes of random data and sets a pointer to
it in the ELF AuxV (the same one that allows us to get HWCAP on ARM
systems). So if we end up in the fallback generator, at leat we'll get a
good amount of entropy to seed the Mersenne Twister.
This could happen if the application is run in a chroot(2) or container
without /dev/random or /dev/urandom. That is probably an installation
mistake, so we don't optimize this case for performance.
With this commit, we have now good, high-quality fallbacks for Windows
(rand_s), for BSDs (arc4random) and for Linux. The only missing,
supported OS without a good entropy source is QNX.

If we've never read any samples from hardware RNG or from /dev/urandom,
then there are no stored samples for us to seed the Mersenne Twister. In
that case, attempt to obtain an emergency sample that consists of some
random bits from the variable addresses (ASLR should help) and from the
clock (using nanosecond quality, instead of seconds).
There's still the possibility that we'll get poor entropy: very close to
boot, if the kernel entropy pool is empty, ASLR could be poor and the
monotonic clock value could be consistent from boot to boot. There's
nothing we can do about that.

First and most importantly, let's not use more than half of the template
for the application's PID. With over 71% of all PIDs on a typical Linux
system and 90% of those on a Darwin system having 5 decimal digits,
using them all in a template that is usually 6 characters long is
wasteful. That leaves only 1 character for the random part, thereby
reducing the number of temporary files possible to only 52. So limit the
PID to half the characters of the template.
Second, let's use QRandomGenerator::bounded to create the the random
part, instead of qrand (which is often unseeded at this point).

This class provides a reasonably-secure random number generator that
does not need seeding. That is quite unlike qrand(), which requires a
seed and is low-quality (definitely not secure).
This class is also like std::random_device, but better. It provides an
operator() like std::random_device, but unlike that, it also provides a
way to fill a buffer with random data, not just one 32-bit quantity.
It's also stateless.
Finally, it also implements std::seed_seq-like generate(). It obeys the
standard requirement of the range (32-bit) but not that of the algorithm
(if you wanted that, you'd use std::seed_seq itself). Instead,
generate() fills with pure random data.

QTimeZone("UTC") should be valid, as "UTC" appears in the list of
availableTimeZoneIds(), and tst_QTimeZone::dataStreamTest() constructs
timezones like this, which are considered valid.
The internal representation of a QTimeZone("UTC") as created by
QTimeZone::QTimeZone(const QByteArray &ianaId) is a QUtcTimeZonePrivate
which isValid(), so the containing QTimeZone isValid() too.
When QTimeZone is serialized into a QDataStream, it calls
tz.d->serialize(ds) which is QUtcTimeZonePrivate::serialize. This
writes QStringLiteral("OffsetFromUtc") followed by the IANA ID and
the offset (etc.) to the datastream.
When QTimeZone is deserialized it looks for this marker string, and if
present, it passed all of the parameters to the QTimeZone constructor
(not just the name). However, that constructor does not support standard
IANA timezones (only custom ones), and when it detects that the supplied
IANA ID is actually listed in availableTimeZoneIds(), it leaves the
pointer to the QTimeZonePrivate uninitialized (NULL), which leaves
the QTimeZone invalid (isValid() returns false).
Thus, a valid timezone which was serialized and then deserialized has
become invalid. This also affects serialization of QDateTimes with
timezones.
Fixed by calling the name-only constructor first, which works (only) for
IANA standard timezones and leaves the QTimeZone invalid (isValid()
returns false) otherwise. In which case, we can call the many-argument
contructor to create a custom timezone with the same offset as the one
which was originally serialized.
