On Debian the examples are built against system's libraries, so there is no
need to set RPATH/RUNPATH.

Upstream processes archs from time to time and tends to disable those that
they do not know wether they are working or not.
SH is working on Debian, so as an intermediate measure re enable it here.

[PATCH] Revert "QProcessEnvironment: simplify locking"
This reverts commit
c5d6b263c204cb09db2be36826e19acb03dc24fb.
The commit being reverted assumes the mutex is only protecting 'nameMap'
and nothing else is mutable, which is false. The mutex is not only
protecting 'nameMap' but also protecting the containing value objects,
since even though the value object is accessed read-only, its
implementation mutates its internal states for 2-way conversion between
ByteArray and QString.
Commit
85e61297f7b02297641826332dbdbc845a88c34b ("restore
QProcessEnvironment shared data thread safety on unix") said that
implicit sharing together with 'mutable' is a time bomb and the bomb is
triggered by the reverted commit.

[PATCH] QFileSystemEngine: handle copy_file_range() returning ENOSYS error
This shouldn't have happened, because minimum-linux_p.h would have
declared our need for a Linux kernel 4.5 or higher. I think the issue is
not the kernel, but a container wrapping the Qt application and
filtering system calls for security. If this container hasn't been
updated to know about the system call, it may cause an ENOSYS error.
Because we now handle the condition, this commit removes the 4.5 minimum
Linux version requirement from minimum-linux_p.h.
[ChangeLog][QtCore][QFile] Added a workaround to a compatibility issue
of the copy() implementation in some containerized Linux environments,
which could cause the file copy to fail with a "Function not
implemented" error. This is believed to be a bug in the container
runtime, not Qt, in that the container wrongly filtered the
copy_file_range(2) system call that the Linux kernel supports.

[PATCH] rhi: vulkan: Fix unintentional SDR format selection
I needed to read back the swapchain image for my Vulkan RHI-enabled
QtQuick application, but it complained that
VK_FORMAT_A2R10G10B10_UNORM_PACK32 wasn't able to be read back - why?
My initial naive solution is to simply add it to the
swapchainReadbackTextureFormat function - but that wouldn't work as
there is no BGR10A2 RHI texture format and applications would unkowingly
end up with swapped channels. The actual problem came down to how we
were selecting swapchain image formats.
The first thing I changed was the hdrFormatMatchesVkSurfaceFormat
function, because that checked two formats for HDR10:
VK_FORMAT_A2B10G10R10_UNORM_PACK32 and
VK_FORMAT_A2R10G10B10_UNORM_PACK32. Checking the online Vulkan hardware
database, the BGR variant is more well-supported. Picking the RGB
variant is inevitably going to lead into the problem described before -
and should be added back when & if a new RHI texture format is
introduced.
The next thing I changed was the swapchain format selection logic,
specifically the choice for a non-sRGB SDR format. Judging by the
comments in this function and other RHIs like DX12 we *want* the default
color format of VK_FORMAT_B8G8R8A8_UNORM unless otherwise requested.
That isn't what was happening though, on my specific hardware it was
choosing VK_FORMAT_A2R10G10B10_UNORM_PACK32 - why?
It comes down to the isSrgbFormat check in the loop. Again, for the
non-SRGB SDR case the "srgbRequested" variable is always false. And when
a non-SRGB format (like the aforementioned problematic VkFormat) is
checked isSrgbFormat will return false, but I don't think that's what is
intended here. We want that for the sRGB case, but for non-SRGB SDR the
default color format is fine and that lines up with other RHIs
(see QD3D12SwapChain::chooseFormats for an example.) I checked this
inside the loop so the passthrough code is still ran on Wayland, but I
think the new logic is still sensible.
I tested this against the five usual cases I could think of and now the
format selection seems sensible:
* non-sRGB SDR chose VK_FORMAT_B8G8R8A8_UNORM
* sRGB SDR chose VK_FORMAT_R8G8B8A8_SRGB
* extended sRGB Linear chose VK_FORMAT_R16G16B16A16_SFLOAT
* HDR10 chose VK_FORMAT_A2B10G10R10_UNORM_PACK32
* Display P3 chose VK_FORMAT_R16G16B16A16_SFLOAT
