This adds the option to build Qt with libb2, which is especially
recommended, if you care about the performance of the BLAKE2 hashing
algorithms. The bundled version is the pure reference C implementation
of BLAKE2, while libb2 has many additional hardware optimizations.
However, the API of both is the same, so no changes to the code were
necessary here.

BLAKE2 does not specify requirements about specific hash sizes and
since QCryptographicHash does not support dynamic hash sizes, only the
most common hash sizes could be covered by this.
The supported hash sizes were chosen to match the ones supported by the
Linux kernel.
The new hashing algorithms for QCryptographicHash are:
* BLAKE2b (160 bit, 256 bit, 384 bit, 512 bit)
* BLAKE2s (128 bit, 160 bit, 224 bit, 256 bit)
[ChangeLog][QtCore][QCryptographicHash] Added BLAKE2b and BLAKE2s

Often a simple change in the styleoptions is needed in e.g a paintEvent,
but it was impossible without copying the whole paint-function which
is not always trivial and also wouldn't be kept up-to-date if it was
changed in Qt.
The initStyleOption is similar to viewOptions in QAbstractTableView
and it is handy that this function is virtual. Furthermore
QStyledItemDelegate::initStyleOption is already virtual.
This change only makes initStyleOption virtual for public classes.
[ChangeLog][QtWidgets] InitStyleOption has been made virtual in

QFileInfoGatherer creates QFileInfo objects in the worker thread to
offload the work from the UI thread, but it never calls any methods on
the QFileInfo objects that would trigger a stat'ing of the files. For
large directories on remote file system, that easily results in the
UI thread being blocked for a very long time.
Add a private 'stat' method to QFileInfo which allows forcing it to
stat all attributes from the worker thread, and make
QFileInfoGatherer a friend so that it can call the function from the
worker thread. This way, QFileSystemModel can access the cached data
for each QFileInfo object, without having to touch the file system
from the UI thread.
Also reduce the amount of signal emissions for drive information,
batch all drives (which can safely be assumed to be at most a two
digit figure) into a single emission instead.

I could have replaced size() - 1 with int(size() > 1) - 1, but that's

Our CMake build system only generated working .prl files for

qtmaind.lib(qtmain_win.cpp.obj) : error LNK2019: unresolved external
symbol __imp_CommandLineToArgvW referenced in function WinMain
The symbol is located in shell32.dll, which was not linked in, because
there was no qtmaind.prl file.
The fix to generate per config prl files is a bit complicated, because
add_custom_command does not support generator expressions in OUTPUT
and DEPENDS.
Instead we pre-generate 2 files per config, one with the preliminary
prl file content and another file that contains the final prl file
path (via generator expression).
Then we iterate over all configurations and create custom commands
with well known paths, and the final prl file is created by the script
called by the command.

On Windows, if Qt is built with Vulkan support but the user's machine
does not have Vulkan, it should still be possible to configure and
build an application (if the application does not use Vulkan of
course).
When Qt is built with qmake, the special windows_vulkan_sdk.prf file
makes sure not to export build time Vulkan include headers into the
generated .pri files. The same file also tries to find the include
headers via an environment variable. If it isn't set, it just adds a
bogus "/include" include path, which doesn't fail a user's application
build.
This wasn't the case for an application built with CMake, because the
exported Vulkan_nolink target uncodinitionally referenced Vulkan's
target properties. Which means that if the Vulkan package was not
found, the application failed to configure.
To mimic qmake's behavior, make sure to query the target properties
only if the Vulkan target exists, via the TARGET_EXISTS generator
expression.
Apply the same logic to all _nolink targets. This might not be
entirely correct in all cases, but we can revise this behavior later
after more feedback. At the very least it allows building non-Vulkan
based applications.
