[qtbase] QLocale data regenerated with initial Tatar locale support. Fixes MER#1707

The Tatar locale data is taken from the recent CLDR tag (v30.0.2), but all other locales kept the same version (v23.1). The language data is inserted in between, so it moves a lot of other locale data, which increases the diff.

Fix the problem with QNetworkAccessManager getting stuck in NotAccessible state

It appears that `QNetworkAccessManager` can keep receiving queued signals even after it has cleared its reference to `QNetworkSession` and disconnected the slots. That can mess up `networkAccessible` state. Particularly, `QNetworkAccessManager` can get stuck in `NotAccessible` state and refuse to submit new network requests until the next online state change signal pulls it out of this state.

There still may be a possibility that a signal from an old `QNetworkSession` could arrive when `QNetworkAccessManager` has already switched to another `QNetworkSession`, but this scenario is probably broken by design, since for whatever reason `QNetworkAccessManager` is only tracking one `QNetworkSession`. In any case, it's far less likely than the scenario which I was trying to fix.

See merge request !3

The next stateChanged() may already be queued by the time we have received
closed() signal and cleared the session reference. Sometimes that was
resulting in QNetworkAccessManager getting stuck in NotAccessible state.

Original commit 198009db

Fix several regressions in font selection

In Qt 5.3.0 a change was added which automatically adapts Common
script to surrounding scripts in accordance with the Unicode tr#24.

This broke *a lot* of cases of font selection because the font
selection algorithm is not prepared for handling characters with
adapted scripts. We need to disable this change for now and redo it
later with patches to font selection to avoid the regressions.

combining different writing systems in the same text.

Original commit 0ec07b68

Improve the Unicode script itemization implementation

Make it closer to the Unicode specs (UAX#24):
* Common now inherits the preceding character's script, if any;
* In a combining character sequence, if the base character is
  of Common script, the entire sequence is treated like if it were
  of the first non-Inherited, non-Common script in the sequence.

eglfs: Allow scaling down the window surface

This patch introduces the QT_QPA_EGLFS_SCALE environment variable.
When set to an integer number > 1 it will scale the draws window
content down by that scale factor.

This is only needed for the Sailfish SDK emulator, for now and i'm
not sure this belongs upstream.

    Send events when platform surfaces are created/about to be destroyed

    These synchronously delivered events allow applications to correctly
    and conveniently handle native platform surfaces being destroyed. This
    is particularly useful when doing rendering on a non-gui thread as it
    allows to shutdown rendering before the native surface gets destroyed
    from under us.

Make platform plugins, like the windows one, able to indicate
if a mouse event is synthesized from a touch event by the OS.
This will be valuable information for the Quick2 event handlers.

No new member variables are added to QMouseEvent. Instead, the enum
value is encoded in the caps member, there are plenty of bits
available in it.

This introduces Qt::MouseEventSource and QMouseEvent::source() as
public APIs.

This change introduces the class QWindowSystemEventHandler

One use case is to intercept key events from the underlying system
in QtCompositor and feed them into the xkbcommon state, and to modify
the events based on the resulting state.
