For a11y purposes, a table needs to be mapped into a logical
accessibility hierarchy. There are several ways of doing this mapping,
and unfortunately macOS expects something different than what
QAccessibleInterface does.
So suppose we have a a 2x2 QTableView with both horizontal and vertical
header like this (the names reflect the QAccessible::Role names):
+-----------+--------------+--------------+
| | ColumnHeader | ColumnHeader |
+-----------+--------------+--------------+
| RowHeader | Cell | Cell |
+-----------+--------------+--------------+
| RowHeader | Cell | Cell |
+-----------+--------------+--------------+
In order to be presented to the screen reader on a platform, it goes
through two rounds of mapping:
QAccessibleInterface will have all headers and cells as direct children of the table:
- Table
+- ColumnHeader
+- ColumnHeader
+- RowHeader
+- Cell
+- Cell
+- RowHeader
+- Cell
+- Cell
macOS expects a deeper hierarchy:
- AXTable [QAccessible::Table]
+- AXRow [Qt:no eqiuivalent]
+- [QAccessible::Cell] (The content of the cell, e.g. AXButton, AXGroup or whatever)
+- [QAccessible::Cell] (The content of the cell, e.g. AXButton, AXGroup or whatever)
+- AXRow
+- [QAccessible::Cell] (The content of the cell, e.g. AXButton, AXGroup or whatever)
+- [QAccessible::Cell] (The content of the cell, e.g. AXButton, AXGroup or whatever)
+- AXColumn (this seems to just store the geometry of the column)
+- AXColumn (this seems to just store the geometry of the column)
+- AXGroup (this represents the column headers)
+- AXSortButton (clicking a header cell will trigger sorting)
+- AXSortButton (clicking a header cell will trigger sorting)
It's unclear to me how RowHeaders are mapped (they are rarer than
ColumnHeaders, I expect to find them in e.g. spreadsheet applications).
I haven't found any native usage of them. So this patch simply ignores
them.
Notice that macOS have a three layer deep hierarchy to represent a table
(Table->Row->Cell), while QAccessibleInterface has a two-layer deep
hierarchy (Table->Row/Cell).
In the macOS bridge we therefore need to "inject" the Row/Column element
to be "between" the table and the cell.
The table will take ownership of all row and column elements that are
children of the table. These elements are not inserted into the cache
(it would be pointless, since the cache is basically just a mapping
between the QAccessibleInterface -> QMacAccessibilityElement, and the
row and column elements does not have a corresponding
QAccessibleInterface to be mapped from).
The rows and columns are therefore also created as soon as the table
element is initialized, and they are stored in two NSMutableArray
members of QMacAccessibilityElement.
A table is constructed like any other accessibility element, with a
valid axid and synthesizedRole set to nil.
Each child row and column element is constructed with the same axid as the
parent table element, and they will have the synthesizedRole set to
either NSAccessibilityRow or NSAccessibilityColumn.
With the synthesizedRole member we can then identify if we are a row,
column or the actual table, and implement their respective behaviors.
Notice that the child row/column is created with the parent's table axid
in order for them to have a way of finding their parent table element.
(there is no 'parent' member variable in QMacAccessibilityElement)
This glorious scheme isn't pretty, but seems to work.

QListView::currentChanged sends an accessible focus event even if the
list view doesn't have focus. For screen readers like Orca, accessible
focus events will be ignored if the target item does not have focus
when screen reader receives the event.
This corrects the behavior by calling QAbstractItemView::currentChanged
before sending an accessible focus event.

The WinRT NetworkStatusChanged callback may happen during or slightly
before we unregister our token, which we usually follow up by destroying
the object. So we have to avoid potentially doing work on a deallocated
object.
Do this using the old QPointer-trick. Neither me nor reporter can
reproduce it locally, so this is only a best-measure.
Further problems may be that the storage for the lambda has already
been destroyed and repurposed, in which case the pointer may be valid,
but junk, which would lead to another crash. But this is unavoidable as
long as MS does not synchronize callbacks with (un)registering new
callbacks. To attempt combatting this we hold our own lock around
unregistration and the "meat" of the callback.

Implementors are expected to return whether the converter can convert
both ways between a mime and a uti. However, this is implied in the
mimeForUti and utiForMime functions, and almost all converter implemented
canConvert by returning mimeForUti(uti) == mime.
A notable exception is the QMacMimeTypeName implementation, which can
only convert from from mime to uti using hard-coded special format names
and dummy data to provide place holders for drag'n'drop operations that
originate in Qt. That converter returned always false from canConvert,
but mapped the special "application/x-qt-mime-type-name" mime type to
the special "com.trolltech.qt.MimeTypeName" uti. Since nobody ever
requests data as "com.trolltech.qt.MimeTypeName", we still always ignore
that converter. The uti is then special-cased in the QMacClipboard code.
Lower-level code where only mime type or UTI are known can still call
the virtuals directly and check whether the returned string is empty,
which indicates that the converter does not support the conversion.
As a drive-by, fix coding style and variable naming.

The check for isBackgroundLocationApi29 has been removed,

Since Android's platform permission API doesn't have an
Undetermined status, we keep a hash of the status for each
permission type, and by default checkPermission() would
return Undetermined, until a requestPermission() call
is done which updates the internal hash, and after that
