0bc4288689 in Qt 5.6 introduced support for premultiplied alpha in the
raster-rendered QWidget content. Unfortunately this introduced a
regression for OpenGL content from QOpenGLWidgets with WA_StacksOnTop
set: these used standard alpha blending in 5.5 and earlier, and
switching them to premultiplied (in case the - unrelated - raster
content has a _Premultiplied QImage format) breaks all content that
was done with non-premultiplied alpha in mind, for example the qopenglwidget
example's "Transparent background" checkbox.
Restore the pre-5.6 behavior.

When cross compiling on Ubuntu with LTO enabled, the linker will complain about the "-fno-fat-objects" parameter even if the "-fuse-linker-plugin" is passed it.
But if the "-fno-fat-objects" parameter is removed, the linker will complain about "don't support linker plugin in this mode".
Remove both parameters can fix this.

After 'h2c' mode was implemented with the proper protocol
upgrade, the previously working 'direct connection' mode
was lost for clear text connections due to the erroneous
logic in the constructor: having !channel->ssl does not
necessary mean we started with HTTP/1.1 request, including
protocol upgrade header; it can also mean we connected a
plain socket and immediately sending h2 frames, without
any H2 negotiation at all.

TestMethods::invokeTest() has an outer loop on global data (albeit
with a comment that said otherwise). On its first cycle, we run the
test function's *_data() method, if it has one; there is an inner loop
on the rows this created. If the *_data() QSKIP()s, we need to skip
the whole test; otherwise, a QSKIP() in one sub-test should not lead
to skipping the remaining sub-tests.
Moved the check for *_data() QSKIP()ping to right after *_data()
returns, inside the "first global cycle" block that runs it.
Previously, this check was done before entering the loop on local data
rows, but outside that "first global cycle" block: consequently, later
global cycles would fall foul of this check (even though the *_data()
hasn't been run in this cycle, much less QSKIP()ped in it) if the last
sub-test of the previous global cycle had QSKIP()ped.
When running a single test for one specific data row, if the test's
*_data() QSKIP()ped, this misplaced check would also have lead to a
misleading "Unknown testdata" warning.
Changed testlib/selftests' tst_globaldata::skipSingle() to trigger the
bug (by having its last local row of first global row skip, which
caused the second global row to be omitted) to verify this is also
fixed; and amended one of its comments to reflect what's now to be
expected. Updated the test's expected output files.

Removing connections and resizing the signal vector now
happens in a way that will not interfere with activate(),
as the old objects won't get deleted if we are somewhere
inside a signal emission.
This means that we don't need to lock the senders mutex
in activate anymore, as long as the reference counting
on the ConnectionData is atomic and we are in the senders
thread.
This implies that we now need to lock the receivers mutex in
queued_activate() abd blocking queued activation to ensure
it hasn't been deleted while we are emitting.
In addition, some precautions need to be taken to not read
from the receiver without holding the lock, as it could get
deleted while we're activating (if it's in a different thread).
To make that possible store the receivers thread id in the
connection data.
Use atomic pointers for all variables that can get modified
with the signalSlotLock() held and that are being read
without the lock being held.
This gives us a very nice additional speed improvement
for signal emissions.

Put all connections that get disconnected into a singly

Whenever the refcount on the connectionData drops down to
one, this list can safely be cleared, even with the planned
removal of locking in activate().
Use an id integer in the connection to acoid activating newly
added connections.
