890edc45d8 QSslSocket: improve documentation of the supported protocols
1) To describe a protocol version we should use an "ordinary" name,
not use the values out of the QSsl::SslProtocol enum.

2) Say that we support the latest stable TLS version (1.2, not 1.0).

3) Fix a statement about which protocol is the default one.

1e662ff166 winrt: Set minimum SDK version to 10586
10586 reflects Update 1, which is the mininum supported version for many
months, hence reflext this in the manifest template as well.

There are additional features (like drag and drop) which require and
even later SDK version. However, they do not reflect the minimum.

faeaddc1b9 QSslSocket::transmit (macOS/iOS) - do not use invalid context
1. QSslSocketBackendPrivate::transmit can invalidate SSL context
  causing subsequent SSLWrite or SSLRead calls to fail; these report
  errSecParam (as null context is an invalid parameter) spuriously,
  when we should rather report the cause of invalidation.  The OpenSSL
  backend can trigger this when it aborts connection during an SSL
  handshake, on an sslErrors signal.  As transmit() emits readReady(),
  a directly connected slot can trigger the same problem if it aborts or
  closes.

2. If during peer verification (and in checkSslErrors) we disconnect
on sslErrors signal, peer verification must be considered failed and
should not continue handshake/set connectionEncrypted.

db1a6ac357 Fix shortcut handling for level three and above shortcuts
Calling `xkb_state_update_mask` with correctly set `depressed_mods` allows xkb to
return keys on level three or above (and not the equivalent level one key).

To preserve level two shortcuts (return equivalent level one key)
`depressed_mods` gets only set, if the pressed key is on level three or above.

Example shortcuts which now will work:
  Shortcut  German Layout (de) [AltGr is a level three switch]
  Ctrl+@    Ctrl+AltGr+Q
  Shift+1   Shift+1  (as before)

  Shortcut  German Neo Layout (de neo) [1] [AltGr is a level five switch]

2a7cee47e5 Avoid artifacts when hiding or closing a QOpenGLWidget or QQuickWidget child
windows and xcb enables SwitchableWidgetComposition meaning that widget
backing stores will fall back to the normal flush path when no render-to-texture
widgets are visible anymore in the window. This switch however can lead to
artifacts with the image of the rtt widget remaining visible until the next
full bacinkgstore sync. The safe and simple way around this is to do the
switch only in the next flush, keeping the flush where the switch is
discovered on the OpenGL-based composition path still.

d2bffe0fc9 UIKit: Detect swapBuffers on non-exposed windows and skip flush
When using threaded rendering the render-thread might be half-way into
rendering a frame when the application is backgrounded, resulting in
the following swap happening on a non-exposed window. This may result
in the system killing the application, as rendering is not supposed to
happen when an application is backgrounded, so we skip the flush.

3e4f885f0c UIKit: Ensure that Qt's application state is initialized at startup
Using dispatch_async to deliver the initial application state at startup
was broken, as that would leave the application in the default application
state, inactive, until the next runloop pass. This became a problem when
an application was started backgrounded, eg. in response to location
updates or a Bluetooth accessory waking it up, as it would have a small
window of time at startup where it would think it was able to render
content (since the window was exposed), while in fact the application
was running in the background. iOS will in these situations kill the app
for doing background rendering.

655687d84d UIKit: Don't reallocate renderbuffer on QIOSContext::swapBuffers()
During device rotation, the backing CEAGLLayer of our custom UIView is
resized by the system. Normally this is the time where we would then
reconfigure the corresponding renderbuffer that we render to, which
shares memory with the CEAGLLayer, but we chose a lazy approach where
we'd defer the reconfigure until client code actually called makeCurrent.

This caused problems because not only did we implement the lazy reconfig
in makeCurrent, but in every QIOSContext function that operated on the
default FBO, including swapBuffers(). When using threaded rendering,
such as in Qt Quick, the render thread may be half way in rendering a
new frame when the system resizes the CEAGLLayer, and we pick up that
resize on the swapBuffer call and allocate a new renderbuffer, before
flushing the queued up GL commands that were operating on another
renderbuffer of a different size. This resulted in the following crash:

  0 - gpus_ReturnObjectErrorKillClient()
  1 - gpusSubmitDataBuffers()
  2 - glrFlushContextToken()
  3 - flush(__GLIContextRec*)()
  4 - QIOSContext::swapBuffers(QPlatformSurface*)
  ...

We solve this by still being lazy in how we reconfigure, but limit the
reconfigure to makeCurrent(). If the CEAGLLayer is resized in between
two frames, we skip the half-drawn frame. The old frame will then be
scaled to match the new size by the system, but this is preferable to
flushing a new frame that may have been drawn with two conflicting
window geometries.

fc1092cfad correctly link xcb-static lib
this apparently makes no difference except for not creating bogus .prl
files - presumably, the correct path is coming from somewhere else
already.
