After e109b8a0f3, it is possible
that the cache will be flushed as a result of inserting a new
font rather than just when the timer event triggers. When doing
superscript and subscript text layouts, we would first get
a regular font engine, then a scaled one, and then reference
the regular font engine *after* getting the scaled one. If the
regular font engine was deleted as a result of inserting the scaled
one, we would get a dangling pointer and crash.
The situation was improved by 49926bb9ef.

QDateTimeEdit ignores the time-spec of its date-time value, using its
own time-spec instead; mostly, this works because it first conforms
the value to its own time-spec. However, during construction, before
doing this, it set up its display data, which could leave it with a
different time (rather than a different representation of the given
time) than it was asked to use.
Moved the updateTimeSpec() calls to immediately after setting value in
QDateTimeEditPrivate::init() to ensure correct handling. Added test.

Earlier versions of the compiler cannot default
move special member functions, even though we
also define Q_COMPILER_RVALUE_REFS for them.
Fix by retracting the less-often-used of the
two compiler feature defines.
Q_COMPILER_DEFAULT_MEMBERS is not used outside
QtBase in neither 5.6 nor 5.7 (5.8 is not
released at this time, so wasn't considered).
The same is true of the dependent macros
Q_COMPILER_DEFAULT_DELETE_MEMBERS and
Q_DECL_EQ_DEFAULT.
In QtBase, the three uses are:
1. in QAtomic*, where the user also requires
Q_COMPILER_CONSTEXPR, which is not defined
for any MSVC at this time,
2. for QEnableSharedFromThis, which is a class
template with an alternative {} implementa-
tion of the default constructor, and uncon-
ditional user-defined copy special member
functions.
3. The test of the corresponding functionality
in tst_compiler, which this commit amends.
That means that neither of these two only uses
of the macro in Qt libraries are affected by
the change.
The reason we do this change, then, is that in
the future, we want to be able to more easily
restore move special member functions for
classes for which they are suppressed due to
user-defined dtors or copy special member
functions.

Restructured, separated the canonicalising of output lines out (into
an object that prepares the necessary regexes and replacements)
suppress more, changed the path-stripping to strip qtbase's parent
rather than os.getcwd() and took account of shadow builds (so both
source tree and build tree provide prefixes we want to strip from
paths). Also cope with $PWD potentially having symlinks in it, where
os.getcwd() is canonical.
It's possible some output might name files elsewhere in the source
tree; these won't be filtered by the prior cwd prefix removal; and, in
any case, the problem with cwd is only that the ancestry of qtbase is
apt to vary; paths relative to there should be consistent between test
runs. This change shall lead to a one-off rewrite of all expected_*
files; but it should now catch all paths. By stripping both build
root and source root (when different) it also avoids differences for
those doing out-of-source ("shadow") builds.
In our XML formats, any hyphens in root paths (e.g. I had Qt-5.6 in my
build root's path) got represented by a character entity, confounding
the replacement; so also do replacement that catches this. We may
discover other character entity subsitutions needed along with this.
Now filtering line numbers and timing information, including benchmark
results; these numbers all get replaced with 0 to avoid noisy diffs.
Also purging dangling hspace, to placate sanity-bot.
The module can now be imported - the code it runs is packaged as a
main() function that a __name__ == '__main__' stanza runs - and all
data is localised to where it's needed, rather than held in globals.
Tidied up and organized the existing regexes. There are doc-strings;
there is a short usage comment. Data is localised rather than global
and modern pythonic idioms get used where apt.
Regexes are compiled once instead of repeatedly. An object looks
after the list of patterns to apply and its construction handles all
anticipated problems. Failures are mediated by an exception.
The output file now gets written once, instead of twice (once before
editing, then over-write to edit), and Popen uses text mode, so that
write can do the same. Its command is delivered as an array, avoiding
the need to invoke a shell.
Instead of relying on qmake being in our path (which might give us a
bogus QT_VERSION if the one in path doesn't match our build tree), use
the relative path to qmake - we rely on being run in a specific
directory in the build tree, after all. Escape dots in the version
properly, so that 51730 doesn't get mistaken for 5.7.0 (for example),
and moved this check later in the sequence (matching a smaller target
makes it more likely to falsely match).
Overtly check we are in the right directory and tell the user what we
actually need, if run from the wrong place. Simplify handling of the
unsupported use-case for MS-Windows (but note what would be needed for
it).
