This has undesired effects when converting a QSqlRecord to JSON.
A char(0) e.g. has special semantics that are undesired when
reading a Tinyint column.
I don't think that returning bool for the special case of a
Tinyint(1) is required. This also did not happen before, and
is also not happening when not using a prepared statement.
Instead, a plain int/uint QVariant is returned.
This patch extends tst_QSqlQuery::integralTypesMysql to also
cover reading and writing booleans from/to a MySQL table column
of type Tinyint(1). Additionally, the reading is now also done
with a prepared statement and we also check the raw variant
value.
The broken behavior fixed by this patch was introduced by me in
commit 194403a348.

Child widgets should get the show/hide event when the TLW changes its
state, because child widgets are also visible or invisible. This
restores the Qt4 behavior (fixes the Qt4->Qt5 regression).
Restoring/minimizing the TLW now sends the spontaneous show/hide event.
Show events are now handled also in the expose event handler in the
QWidgetWindow class, because the show event must occur before the
expose event to avoid possible flicker e.g. the OpenGL content. This
can happen e.g. on XCB platform. If the "WindowStateChange" event occur
before the expose event (e.g. Windows platform) then the code in expose
event handler will be ignored to prevent event duplications.
Added autotest.

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).

The limitation of four glyph caches per font engine was to prevent memory
spikes during rotation of text. But in an application with multiple top
level OpenGL windows, each with their own context, we'd end up trashing
the list of glyph caches during rendering, even if each window just drew
the same static text.
Having a shared context between the windows helped a bit, but had other
performance issues due to the globally shared state, so the better approach
is to limit the caches to four per context.
This brings the multiwindow manual test from a grinding 4fps on macOS
