The Unix stat fields "st_ctime" and "st_ctim" mean "change time", the
last time that the file/inode status fields were changed. It does not
mean "creation time". So this commit splits all of the internal API to
"birth" and "metadata change" instead of "creation" to avoid the
conflict.

[ChangeLog][QtCore][QFileInfo] Deprecated created() because it could
return one of three different file times depending on the OS and
filesystem type, without the ability to determine which one is which. It
is replaced by metadataChangeTime() and birthTime().
[ChangeLog][QtCore][QFileInfo] Added QFileInfo::metadataChangeTime(),
which returns the time the file's metadata was last changed, if it is
known, and falling back to the same value as lastModified() otherwise.
On Unix systems, this corresponds to the file's ctime.
[ChangeLog][QtCore][QFileInfo] Added QFileInfo::birthTime(), which
returns the file's birth time if it is known, an invalid QDateTime
otherwise. This function is supported on Windows and on some Unix

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.)

This needs a zone with transitions near the epoch; and the only CET
with DST that winter was Italy (copied by Malta), for which the Olson
database had a recent (2016) correction to its data, for that winter.
That means we get inconsistent results on O/Sen of different ages.
So add a separate testEpochTranPrivate(), alongside testCetPrivate(),
and test it with America/Toronto. (Unfortunately, MS-Win gets the
date wrong on the first transition after the epoch, so we have to code
round that.)
Since information before the epoch isn't reliably available, only test
the search backwards if nextTransition does find something before it.
(We can safely assume all real transitions happened since 1601;
non-celestial time-keeping wasn't accurate enough, before that, for
anyone to synchronize with anything but celestial time.)

When QCOMPARE(,) reports two 12-digit numbers, it's not always
immediately obvious what the difference is (much less what 1/3600000
of it is); nor is it obvious that (or why) a given 12-digit number is
in fact correct. In contrast, our eyes can make sense of a
QDateTime's reported value quite well, enabling us to see what's
different; and it's possible to at least confirm the plausibility of
2-or-3 am on a spring or autumn day at a plausible transition (or even
to confirm it exactly by consulting suitable web-sites). Also
document the actual transition happening in each case (since I *did*
consult a suitable web-site). So prefer to QCOMPARE(,) two QDateTime
values instead of two 12-digit qint64s.
Where a that would be unsuitable, at least compare the difference to
zero, to make the error easier to understand (except when one of the
twelve-digit numbers consists entirely of 9s; that, for once, actually
is easy to see).
Write various multiples of 3600 as the relevant intelligible whole
number times 3600, rather than premultiplying, to make it obvious to

The getentropy function, first found in OpenBSD, is present in glibc
since version 2.25 and Bionic since Android 6.0 and NDK r11. It uses the
Linux 3.17 getrandom system call. Unlike glibc's getrandom() wrapper,
the glibc implementation of getentropy() function is not a POSIX thread
cancellation point, so we prefer to use that even though we have to
break the reading into 256-byte blocks.
The big advantage is that these functions work even in the absence of a
/dev/urandom device node, in addition to a few cycles shaved off by not
having to open a file descriptor and close it at exit. What's more, the
glibc implementation blocks until entropy is available on early boot, so
we don't have to worry about a failure mode. The Bionic implementation
will fall back by itself to /dev/urandom and, failing that, gathering
entropy from elsewhere in the system in a way it cannot fail either.
uClibc has a wrapper to getrandom(2) but no getentropy(3). MUSL has
neither.
