Windows: Fix one of the two file dialog bottlenecks.

This patch reduces the number of calls to GetFileAttributesEx()
when icon lookup is being done.

The second bottleneck is a couple of isSymLink() calls. Will fix
that next.

Windows: Fix the last file dialog bottleneck.

Went from taking 30 seconds to 2 seconds, on a SDCard with 10k files.

Windows file dialog does not resolve NTFS symlinks,
it just shows an empty icon, and the link name, not the target.

This allows for a big performance gain by reducing the number of
calls to GetFileAttributesEx() by checking the extension directly.

This also fixes the problems with the native file dialog, which
for some reason, is creating a QFileSystemModel too.

Improve shapeTextWithHarfbuzz() logic a bit

* Move non-specific code to shapeText();
* Make shapeTextWithHarfbuzz() re-use variables obtained in shapeText();
* Make shapeTextWithHarfbuzz() return amount of shaped glyphs
  instead of nothing. Right now, this is not about error reporting,
  since failed shaping causes assertion/crash in most cases.

In particular, set online state right upon construction of the

Before, this would only work properly if a network session was created.
Now, networkAccessible() returns the correct status.

Add qPopulationCount() function, extracted from QBitArray

This functionality is used in multiple places in Qt itself, so it makes
sense to have a global function for this. This also allows to map this
onto specialized assembler instructions, should an architecture provide
them, later on.

Also added comprehensive tests, using a 4-bit lookup-table implementation
as a reference.
