Fix fallbacks for adapted common script

When the platform plugin gives us specific fallbacks for a
specific script, we need to respect this, and load the correct
font family regardless of which writing systems it supports.

This is especially important since the common script is adapted
to match surrounding, proper scripts, so characters such as
digits next to e.g. Hebrew text will be marked as Hebrew. On
stock Android, there is a single Hebrew font, and this would
previously be put in all fallback slots for Hebrew regardless of
what fallback fonts were dictated by the platform plugin. Since
this font does not support the digits, they would show up as boxes.

[ChangeLog][Android] Fixed common characters like digits and
punctuation showing as boxes when positioned next to non-latin
scripts.

xcb: QTabletEvents and proximity events correctly identify the tool

The tool is enum TabletDevice reported in QTabletEvent::device().
Each type of tool for each type of tablet has an ID which needs to
be mapped to this enum.

The meaning of the AbsWheel valuator depends on the tool type:
an airbrush sends tangentialPressure in the range -1..+1,
whereas an Art Pen (RotationStylus) sends rotation in degrees.

Because the evdev driver sends valuator changes individually, we
have to store the current value in each TabletData::ValuatorClassInfo
to ensure that each QTabletEvent has complete state information.

[ChangeLog][Platform Specific Changes][X11 / XCB] QTabletEvents
and proximity events correctly identify the tool in use; the
meaning of certain valuators depends on the tool; and the valuators'
current values are not lost between events

Work around ICC bug in brace initializations containing constexpr

ICC miscompiles this:

struct Inner { int i; constexpr Inner(int i) : i(i) {}};
struct Outer { Inner i; };
const Outer x = { -1 };

(Inner = QBasicAtomicInt; Outer = QtPrivate::RefCount, then again for
QListData::Data)

We expect x to be placed in read-only memory and require no load-time
constructor. ICC unfortunately does not do that. By adding a constexpr
constructor to Outer, it starts behaving like we expect it to, but falls
apart again if you do "const Outer x[]" (the QArrayData statics).

The solution is to probably make the varaibles constexpr too, but that's
a job for the development branch.

Android: Update QSslSocketPrivate::fetchSslCertificateData()

Replaces the raw jni calls with our own jni wrappers. This allows us
to make use of the centralized cache, avoid global data storage and
use a more optimized way to attach to the jni environment.
This change also removes the JNI_OnLoad() function since it's not
used. If we need to add a JNI_OnLoad() function later, we should find a
more suited place for it.
