sljit, the JIT in pcre2, doesn't quite fully work on windows on
arm yet (although the subset of functionality used by pcre2 might
mostly work). On arm64, it fails to compile (although working around
that failure is pretty easy), when using clang in MinGW mode
(where __GNUC__ is defined, making the JIT auto-enabled).

Disable it in these configurations until it has been fully tested
and fixed upstream first.

The native APIs don't support previous transition, only next after a
stipulated date.  The prior code started its search at the epoch; if
used for a time before the first transition after the epoch, this
found no transitions so returned invalid data, when the last
transition before the epoch would have been suitable.  It also wound
through all transitions since the epoch, on its way to the selected
time, which was potentially laborious.

Instead, start a year before the stipulated time; this should get a
transition if the zone uses DST.  If it doesn't, start with the first
known transition and binary-chop our way to one within a year of the
last before the stipulated time; then wind forward one transition at a
time, as before.  The chopping is actually faster than binary: each
time we find a transition after the interval mid-point but early
enough, we move the early end of our interval to the transition, which
is later than the old interval's middle.  Using halving, starting with
a vast interval, should thus only incur modest cost, while ensuring we
give up early when no transition data is available at all or the
zone's first transition ever was after the stipulated time.

For Q_OS_WIN, a path is only truly absolute if it includes a drive
letter; merely starting with a slash is not enough.  (We can't support
UNC paths, so don't even try: qmake runs various commands in the
source directory using CMD.exe, which doesn't support UNC as PWD.)
This requires, when resolving a path relative to a root, transcribing
the root's drive to such not-quite-absolute paths.

Changed QMakeGlobals, $$absolute_path() and $$relative_path() to now
use IoUtils::resolvePath() rather than delegating to QDir's absolute
path method, since that doesn't correctly recognize the need for a
drive letter (and qmake did run into problems with some paths, from
splitPathList and a failing test, as a result).

Moved existing ioUtils tests for handling of relative / absolute paths
out into separate functions and expanded significantly.  Fixed some
existing tests to use an absolute path where one is needed; added two
tests involving driveless (but rooted) paths; and fixed the test init
to set a value for QT_HOST_DATA/src property (the lack of which lead
to an assertion failure with this fix).

After including windows.h, interface is a define that expands to
"struct" (unless WIN32_LEAN_AND_MEAN is defined). This name is
used as a normal identifier in multiple places within Qt.

This has already been worked around in a number of places
(in e.g. 3ba61d9b and
786d23bb

).

After qrandom.h was included in <QtCore/QtCore>, this header
implicitly includes <random>. In libc++ on windows, this header
then transitively includes windows.h, exposing the clash with
the name "interface" in even more locations than before.

For cases within qtbase internals, it could also alternatively be
handled by defining WIN32_LEAN_AND_MEAN while building QtDbus, but
for occurrences in public headers, the undef trick needs to be
used.
