8fc34e42a8 Add information about unsupported SSL protocol when creating context.
When creating SSL context failed due to unsupported protocol being
demanded, no explanation was given. It's because
QSslContext::fromConfiguration() extracted explanation for error message
from OpenSSL, which at that point hasn't even been called yet. This
patch adds explicit message informing that an unsupported protocol was
chosen.

9ddf2fb376 Prevent parsing of SSL certificates from 0-size buffers.
When QSslCertificatePrivate::certificatesFromDer() was passed count ==
-1 to extract unlimied number of certificates from buffer, it also tried
to parse the 0-sized fragment after the last certificate.  This has
caused d2i_X509() to report an error on latest OpenSSL.

a5b647804b QFactoryLoader: de-duplicate two QStringLiterals
When seemingly identical QStringLiterals are used in different

different lambda types and thus duplicated QStringLiteral data.

Fix by moving the QStringLiterals into inline functions and

For QLatin1String, startsWith/endsWith 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.

05663e29d0 moc: don't use QByteArrayLiteral
The byte array literals are only used to append them to another
QByteArray, so they offer only the static size calculation as a
benefit.

However, there are several drawbacks:
- QByteArrayLiteral data cannot be shared the way string literals
  can be, not even within a single TU, and they add a few ints
  for the QByteArrayData header which cannot reside in BSS, but
  need to be stored in DATA.
- QByteArrayLiteral *does* allocate when the compiler doesn't
  support C++11 lambdas.
- QByteArrayLiteral, when not using RVO, litters the code with
  QByteArray dtor calls, which are not inline, and thus can't
  be optimized away.

In particular, when used like this, they do not prevent any
memory allocation (in fact, they might add some, absent lambdas).

So, just append (C) string literals.

Commit 4f21eb03 utterly broke the project file generation for
VS 2008. The introduced filterByName convenience methods looks for
filter names like "Generated Files", but the code path for
VS <= 2008 used filter names like "GeneratedFiles".
The generated projects were valid but empty.
This commit ensures that both VS generators use the same filter
names.

e5a8134765 fix vcxproj generation for CONFIG-=flat
Commit 4f21eb03 broke the generation of non-flat vcxprojs.
XTreeNode passes filter names to outputFileConfigs that have
the source subdirectory suffixed (e.g. "Generated Files\subdir").
That's why the original code tested the filter names with
QString::startsWith.
I've changed the signature of outputFileConfigs to take a filterId
parameter which contains the unaltered filter name (e.g.
"Generated Files") that will determine the correct filter.

a366b2bb54 qdoc: Fix generation of qhp sections for unsorted pages
If you had the following lines in .qdocconf:

    qhp.QtFoo.subprojects.examples.title      = Examples
    qhp.QtFoo.subprojects.examples.indexTitle = Qt Foo Examples
    qhp.QtFoo.subprojects.examples.selectors  = fake:example

The expected outcome is to see an unsorted list of examples. This
didn't work however, because QDoc assumed to find a chain of
\nextpage links for the indexTitle, and these are rarely used
in Qt documentation nowadays.

This commit ensures that all pages matching the defined selectors
will be listed under the section title, even when the sortPages flag
is not set.

1adc586abd QBrush: be more robust in detach()
If detach() was called with a newStyle corresponding to a gradient,
but with d->style not a gradient, it would execute an invalid cast
and read invalid memory.

The reason this has not been seen in practice is that a non-gradient
brush instance can currently never become a gradient one. But that
may change when someone adds an operator=(QGradient), so in the
interest of robust code, add a check to verify the old style was a
gradient before accessing the corresponding member.

839ceb00b0 tst_QFiledialog::completer(): Avoid directories starting with 'c'.
Apparently, this causes problems with the completer due
to the fact that it matches the root drive "C:\" on Windows.

1126efed7d iOS: Set up default Info.plist to support all interface orientations
When the UISupportedInterfaceOrientations key is missing, iOS will start
up the application in the orientation defined by UIInterfaceOrientation,
and if that key is also missing, it will default to portrait orientation.

Unfortunately, when the application has finished launching on an iPad,
there is no way to re-evaluate the current device orientation unless the
user actively rotates the device, so for example if the device is physically
in landscape orientation, and the application is started up in portrait,
the application will not auto-rotate to landscape after starting up.

It would seem that [UIViewController attemptRotationToDeviceOrientation]
would be the right API to do this, but even after telling the device
to beginGeneratingDeviceOrientationNotifications the device orientation
will still match the startup orientation until the device is physically
rotated. For iPod/iPhones this is not an issue, as the OS will update
the device orientation after startup. Presumably the difference in
behavior between the two device classes is due to the iPad supporting
any orientation for the application grid.

Since we would prefer the application to either start up in the right
orientation directly, or at least rotate to it after startup, and the
latter can't be done, we apply UIInterfaceOrientationMaskAll to the
Info.plist file. This also has the benefit that the application will
show any splash screens in the right orientation.
