By templating on the <chrono> types and unconditionally using
duration_cast to coerce the duration into a milliseconds, we
allowed code such as
mutex.try_lock_for(10us)
to compile, which is misleading, since it's actually a zero-
timeout try_lock().
Feedback from the std-discussions mailing list is that the
wait_for functions should wait for _at least_ the duration
given, because that is the natural direction of variance
(tasks becoming ready to run might not get a CPU immediately,
causing delays), while an interface that documents to wait
_no more_ than the given duration is promising something it
cannot fulfill.
Fix by converting the given duration to the smallest number
of milliseconds not less than the original duration. If that
is not representable in an int, use INT_MAX, emulating the
effect of a spurious wakeup, which are allowed to happen if
the function returns false in that case.
In the above example, the try_lock_for call is now equivalent
to
mutex.tryLock(1);
The tryLock() docs state that the actual waiting time does
not exceed the given milliseconds, but fixing that is a
separate issue.

Not unloading plugins is Qt's policy, as decided during the 5.0

need duration_cast. By accepting any duration, we allow non-

Overloading a non-template with a template also has adverse

Fix by replacing the function templates with functions that

resolution fails to compile / needs an explicit user-

To allow future extension to more precise timers, forcibly
inline the functions, so they don't partake in the ABI of the
class and we can later support sub-millisecond resolution by
simply taking micro- or nano- instead of milliseconds.

Saving strings with embedded zero-bytes (\0) as CFStrings would
sometimes fail, and only write the part of the string leading
up to the first zero-byte, instead of all the way to the final
zero-terminator. This bug was revealed by the code-path that
falls back to storing e.g. QTime as strings, via the helper
method QSettingsPrivate::variantToString().
We now use the same approach as on platforms such as Windows
and WinRT, where the string produced by variantToString() is
checked for null-bytes, and if so, stored using a binary
representation instead of as a string. For our case that
means we fall back to CFData when detecting the null-byte.
To separate strings from regular byte arrays, new logic has
been added to variantToString() that wraps the null-byte
strings in @String(). That way we can implement a fast-path
when converting back from CFData, that doesn't go via the
slow and lossy conversion via UTF8, and the resulting QVariant
will be of type QVariant::ByteArray. The reason for using
UTF-8 as the binary representation of the string is that
in the case of storing a QByteArray("@foo") we need to
still be able to convert it back to the same byte array,
which doesn't work if the on-disk format is UTF-16.

for that, qt_help_lib.prf gains the ability to write "external module
pri" files that contain suitable information for QMAKE_USE.
these files have a bunch of limitations:
- they are not installed, because a) they are not relocatable and b) the
helper libs' headers are not installed, either
- it won't work with qmake -r, which is ok, as qt5 does not build with
qmake -r anyway
- deps are not transitive, neither at build nor at use time
the freetype, harfbuzz-ng, pcre, and png helper libs have been adjusted
accordingly, and their uses replaced with QMAKE_USE instances. this also
allowed inlining the now trivial {harfbuzz,pcrc,png}_dependency.pri
files. freetype_dependency.pri remains due to its funkiness.

The SSE code had a case where tail-loop unrolling was disabled when
optimizing for size. What would be even shorter, is to just do a
straight-forward loop over the arrays and compare them. For anything
else, we can just go for speed.
