We want to re-enable Android tests in QTQAINFRA-3867. However,
many tests are failing already preventing that from happening.
QTBUG-87025 is currently keeping track (links) to all of those
failing tests.
The current proposal is to hide those failing tests, and enable
Android test running in COIN for other tests. After, that try
to fix them one by one, and at the same time we can make sure
no more failing tests go unnoticed.

Make QPair an alias for std::pair, and qMakePair just a forwarder
towards std::make_pair.
Why? Fundamentally to ditch a bunch of NIH code; gain for free
structured bindings, std::tuple and std::reference_wrapper
compatibility, and so on.
Breakages:
* Some that code manually forward declares QPair.
We don't care about it (<QContainerFwd> is the proper way).
* Some code that overloads on std::pair and QPair. Luckily
it's mostly centralized: debug, metatypes, testing macros.
Just remove the QPair overload.
* Usages of qMakePair forcing the template type parameters.
There are a handful of these in qtbase, but only one was actually
broken.
* std::pair is NOT (and will never likely be) trivially copiable.
This is agreed to be a mistake done by practically all implementations
in C++11, can can't be fixed without breaking ABI.
Some code using QPair assuming it's trivially copiable may break;
exactly one occurrence was in qtbase.
* QMetaType logic extracts the type names in two different ways,
one by looking at the source code string (e.g. extracted by moc)
and one via some ad-hoc reflection in C++. We need to make
"QPair" (as spelled in the source code) be the same as "std::pair"
(gathered via reflection, which will see through the alias)
when compared. The way it's already done e.g. for QList is
by actually replacing the moc-extracted name with the name
of the actual type used in C++; do the same here.
On libc++, std::pair is actually in an inline namespace --
i.e. std::__1::pair; the reflection will extract and store
"std::__1::pair" so we need an ad-hoc fix to QMetaType.
[ChangeLog][QtCore][QPair] QPair is now an alias to std::pair,
and does not exist as a class in Qt any more. This may break
code such as functions overloaded for both QPair and std::pair.
Usually, the overload taking a QPair can be safely discarded,
leaving only the one taking a std::pair. QPair API has not changed,
and qMakePair is still available for compatibility (although
new code is encouraged to use std::pair and std::make_pair
directly instead).

Windows apparently has special code to deal with those addresses. If all
your network interfaces are up and have acquired addresses, then the
link-local network at 169.254.0.0/16 is unreachable. I had never caught
this because both my Windows VM and my bare metal Windows have inactive
interfaces (like the Bluetooth PAN one) and, when inactive, Windows
assigns a link-local address. But in the CI, the interface(s) were all
up and running, causing this issue.
Unix systems don't treat IPv4 link-local any differently, so they always
worked, so long as any interface was up and there had to be one to reach
the network test server.
This commit reworks the test to add test addresses based on the
addresses found on up & running interfaces (see tst_qudpsocket.cpp). For
IPv4, we flip the bits in the local portion of the address. For IPv6, we
add a node with an address I generated randomly (non-universal), with
the same scope.

Lookups performed via QHostInfoRunnable must not synchronously call
the user-code's receiver objects, as that would execute user-code in
the wrong thread. Instead, post a metacall event through the event
loop of the receiver object, or the thread that initiated the lookup.
This was done correctly for the trivial cases of empty host name or
cached results, so the code generally existed. By moving it from a
global function into a member function of QHostInfoResult, we can
simply access the required data to construct and post the event.
As we process that posted event, we need to check that the context
object (which is already guarded via QPointer) is still alive, if
we had one in the first place. If we had one, and it's deleted, then
abort.
[ChangeLog][QtNetwork][QHostInfo] Functors used in the lookupHost
overloads are now called correctly in the thread of the context object.

initTestCase() in the process.

Commit 64a1448d87 (Qt 5.2) caused
QNetworkInterface to report address labels (a.k.a. interface aliases) as
separate interfaces. This is caused by the fact that glibc, uClibc and
MUSL copy the address label (netlink address attribute IFA_LABEL) to the
ifa_name field, which made QNetworkInterfaceManager think that it was an
interface it hadn't yet seen.
Address labels are the old way to add more than one IP address to an
interface on Linux, for example:
ifconfig eth0:1 192.0.2.2
Those do not create a new interface, so the "eth0:1" label maps to the
same interface index as the parent interface. This has been deprecated
for 10 years, but there are still tools out there that add addresses in
this manner.
This commit restores behavior compatibility with Qt 4.2-5.1. The Qt
5.2-5.5 behavior is incorrect because it reports more than one interface
with the same index. On systems configured like the above, the
tst_QNetworkInterface::interfaceFromXXX test was failing.
