Clang-cl couldn't find the header given to it by -FI when it isn't in
any of the included directories.

Additionally clang-cl 8 has a bug with exported templated classes with
inline methods that causes it to have missing symbols at link time. We
work around this.

nowaways it's officially deprecated and even generates a warning in
Visual Studio 2019; so we don't have to 'unset' it specifically anymore.

The comment hints that it's fixing an issue in Visual Studio 2013, which
we don't support anymore.

In all supported Visual Studio Versions -Gm is actually deprecated
anyhow, and not set anymore by default. So I guess it's safe
to remove the special handling here.

Includes a fixup for 03fadc26

, which
removed the check on empty transition list, needed when no data are
available.  Ensured that such a data-free zone would in fact be
noticed as invalid during init().

Fixed handling of times before the epoch (we still want to consult a
POSIX rule, if that's all that's available) while ensuring we (as
documented) ignore DST for such times.

Fixed handling of large times (milliseconds since epoch outside int
range) when looking up POSIX rules.  Gave QTimeZonePrivate a YearRange
enum (to be moved to QTimeZone once this merges up to dev) so as to
eliminate a magic number (and avoid adding another).  Moved
year-munging in POSIX rules after the one early return, which doesn't
need the year range.

Added test-cases for the distant past/future (just checking UTC's
offsets; SLES has a minimal version of the UTC data-file that triggers
the bugs fixed here for them).

Additionally, we also add a Q_TRACE_EXIT which runs a trace point when
the scope is exited, leveraging qScopeGuard behind the scenes.
Q_TRACE_SCOPE uses Q_TRACE_EXIT internally - the difference is that
the _SCOPE version enforces the naming scheme of _entry / _exit for the
tracepoints, whereas Q_TRACE_EXIT can be used generically.

This patch fixes compilation with `-trace lttng` or `-trace etw`. We
need to forward declare QEvent, QImageReader etc., otherwise the types
will be unknown while compiling the trace points.

In order to handle this generically, the tracegen utility is extended
to support a 'prefix text' in the `*.tracepoints` input files. Any
text within curly braces will be embedded as-is in the generated file.
This can then be used to add forward declarations for the types we
need, including potential namespaces and such.

This runtime warning was recently introduced in the fix for an
assert/crash when creating a brush with an invalid Preset
value. However, that overlooked the usage where an unknown value is
passed to QGradient constructor, and the code afterwards checks if
the result is a NoGradient or not. It turns out that such usage is
already established as legitimate, including in the Qt Quick Rectangle
code, so this warning would be spit out continuously for perfectly
legal qml code.

Hardcoding IP addresses and their respective DNS records is fragile.
We care about Qt producing the same result as other DNS querying tools,
so testing that instead.

Running a python script for this is easiest, and assumed to be quite
reliable.

In case where python fails/is not present, fall back to nslookup.
That tool is available on Linux, macOS, and Windows, although the
output it produces varies. This change implements very basic
line-parsing that can interpret the various results encountered
during testing on those platforms.

This also reverts commit bbaceff253fae13d8e56691bc9de7e1981db5118,
which blacklisted the tests that failed due to changes in DNS
records.
