7236721bf8 QJsonObject has random-access iterators
... but they were only marked as bidirectional.

Fixed.

This change is slightly BiC, because if some class used tag
dispatching on this iterator type, a recompile might now
pick a different overload, and the old one may not be
available to a user anymore (no longer instantiated).

I do not think Qt uses that technique, yet, though. Not on
iterator categories, at least.

4c8cb329d4 Accessibility OS X: Fix hang when editing password line edits
This fixes a regression when entering data in a password field.
The important part is to simply not call convertLineOffset for
single line text edits. The reason is that the function when dealing
with password fields gets an empty string back when calling textAt etc.
This is good since we don't want to leak passwords through a11y apis.
The problem with the functions returning empty strings is that we end up
in an infinite loop in convertLineOffset.

14ef6abd0b Accessibility OS X: protect from accessing invalid objects
Usually when getting an object from an interface, the object
can be assumed to be valid. We need to check isValid though
since the screen reader access is inherently asynchronous and
objects might be in the QWidget destructor where the QObject is
still valid.
Thus check QAccessibleInterface::isValid in all uses of it in the
OS X implementation.

0f27d11285 Don't use QStringLiteral in comparisons
For QLatin1String, operator== is overloaded, so comparing to a latin-1
(C) string literal is efficient, since strlen() is comparatively fast.

OTOH, QStringLiteral, when not using RVO, litters the code with
QString dtor calls, which are not inline. Worse, absent lambdas,
it even allocates memory.

So, just compare using QLatin1String instead.

ee9621b9dc Move shortcut handling back into QGuiApplication
c7e5e1d9e0 assumed shortcut handling could be done at the QPA
level, but this fails on async platforms where there are e.g
activation events in the QPA queue and we then try to handle

This commit restores the handling to QtGui for non-OS X platforms,
and we should fix OS X by adding callbacks through the IME for
the special case of OS X.

088eef5756 QStringBuilder: fix appending QLatin1String to QByteArray
The old code did the equivalent of strcpy(), thus stopping
at the first NUL byte, ignoring the QLatin1String's size().

That is not acceptable, for two reasons:

1. Appending QLatin1String to a QString uses the size(), too.

2. The QConcatenable claims an ExactSize = true, so
   it cannot go and write less data than it's own
   size() said it would. Even worse, it will happily
   write _more_ data, too, if the QLatin1String is
   not properly zero-terminated.

This change has low risk, because the equivalent change
to the QString branch has been applied between 5.2 and
5.3 (in fd0f1bc3), with no complaints from the user base.

It is also in a branch that is very unlikely to be taken:
Since QConcatenable<QLatin1String> is setting ConvertTo
to QString, any QStringBuilder expression containing it
will only implicitly convert to QString, not QByteArray.
In fact, I don't even know how to make it invoke the
changed code in normal operation...

a1ba281a26 Call out to QtDBus message spies in the main thread
Whenever there are spies installed, we call out to the main thread to
call to the kded/kiod message spies. This allows the spy code to do just
about anything, where previously it was restricted in what it could do
to avoid deadlocking or triggering assertions if it recursed back into
QDBusConnection code in the manager thread. After the spies are done,
the message is re-inserted into the QDBusConnection processing pipeline.

This commit moves the spy handling to after the check for disabled
dispatching, as doing otherwise would mean the message could get
postponed again for no good reason. It's also possible that the main
thread isn't done installing the hooks, so waiting until the dispatching
is enabled is a good idea.

For simplicity, this commit also restricts spying to method calls
only. Signals are no longer spyable.

f33c6f37a8 Work around MinGW-make's magic prefixing of paths.
When building QNX on MS-Windows, make magically adds the Msys root as
prefix to variables whose values look like paths; this applies to both
environment variables and variables given values on the command-line.
When we don't actually want to install under the Msys root, this is
unwelcome "help".  So (for MinGW's make) support a magic prefix of our
own, @msyshack@, that'll make a path value for INSTALL_ROOT not look
like a path to make; we can then strip it off when we come to use it.

use a fixed size array of double (since we always use 7 elements
to calculate the median anyway).
