This fixes `fetchurl-force.nix` not being installed, which breaks
bundix for some gems.

Issues addressed:
- xcode build failed with
... was built for newer OSX version (10.10) than being linked (10.5)
fixed by setting GYP mac deployment target to the nix value
- a gyp bug when SDKROOT is not set (and removed an orphaned gyp patch
- path to python in generated gyp-mac-tool
- noisy build due to static assert warnings, by silencing warnings
- use of system xcodebuild and libtool replaced by darwin.cctools

XSA-219 Issue Description:
> When using shadow paging, writes to guest pagetables must be trapped and
> emulated, so the shadows can be suitably adjusted as well.
>
> When emulating the write, Xen maps the guests pagetable(s) to make the final
> adjustment and leave the guest's view of its state consistent.
>
> However, when mapping the frame, Xen drops the page reference before
> performing the write. This is a race window where the underlying frame can
> change ownership.
>
> One possible attack scenario is for the frame to change ownership and to be
> inserted into a PV guest's pagetables. At that point, the emulated write will
> be an unaudited modification to the PV pagetables whose value is under guest
> control.

XSA-220 Issue Description:
> Memory Protection Extensions (MPX) and Protection Key (PKU) are features in
> newer processors, whose state is intended to be per-thread and context
> switched along with all other XSAVE state.
>
> Xen's vCPU context switch code would save and restore the state only
> if the guest had set the relevant XSTATE enable bits. However,
> surprisingly, the use of these features is not dependent (PKU) or may
> not be dependent (MPX) on having the relevant XSTATE bits enabled.
>
> VMs which use MPX or PKU, and context switch the state manually rather
> than via XSAVE, will have the state leak between vCPUs (possibly,
> between vCPUs in different guests). This in turn corrupts state in
> the destination vCPU, and hence may lead to weakened protections
>
> Experimentally, MPX appears not to make any interaction with BND*

XSA-221 Issue Description:

XSA-222 Issue Description:
> Certain actions require removing pages from a guest's P2M
> (Physical-to-Machine) mapping. When large pages are in use to map
> guest pages in the 2nd-stage page tables, such a removal operation may
> incur a memory allocation (to replace a large mapping with individual
> smaller ones). If this allocation fails, these errors are ignored by
> the callers, which would then continue and (for example) free the
> referenced page for reuse. This leaves the guest with a mapping to a
> page it shouldn't have access to.
>
> The allocation involved comes from a separate pool of memory created
> when the domain is created; under normal operating conditions it never
> fails, but a malicious guest may be able to engineer situations where
> this pool is exhausted.

XSA-224 Issue Description:
> We have discovered a number of bugs in the code mapping and unmapping
> grant references.
>
> * If a grant is mapped with both the GNTMAP_device_map and

>
> * Under some specific conditions, if a grant is mapped with both the

>
> * When a grant reference is given to an MMIO region (as opposed to a
> normal guest page), if the grant is mapped with only the
> GNTMAP_device_map flag set, a mapping is created at host_addr anyway.
> This does *not* cause reference counts to change, but there will be no
> record of this mapping, so it will not be considered when reporting

The rsync binary was previously built without iconv support which is needed
for utf-8 conversions on darwin. Fixes#26864.
Additionally rsync used to be built with bundled versions of zlib and popt
that were outdated. This decreases the size of the rsync binary by ~82KB.
Removing all `config.mpv.*` options will improve readability. MPV has many
configurable options, and using the config approach is prone to confusion and
unnecessary code duplication. If needed, the user can `override` the relevant
variables in the function itself, so no functionality is lost.
Closes issue #26786
The following errors occur when you start Chromium prior to this commit:
[2534:2534:0625/202928.673160:ERROR:gl_implementation.cc(246)] Failed to
load .../libexec/chromium/swiftshader/libGLESv2.so:

[2534:2534:0625/202928.674434:ERROR:gpu_child_thread.cc(174)] Exiting
GPU process due to errors during initialization
While in theory we do not strictly need libGLESv2.so, in practice this
means that the GPU process isn't starting up at all which in turn leads
to crawling rendering performance on some sites.
So let's install all shared libraries in swiftshader.
I've tested this with the chromium.stable NixOS VM test and also locally
on my machine and the errors as well as the performance issues are gone.

This allows users to specify a custom registry src,
because currently every packager would need to create
an outdated Cargo.lock just to be compatible with the
probably outdated rustRegistry in nixpkgs.
Currently there is no easy way to convince cargo to
do that, so this makes that workaround unnecessary.

Qt 5.8 is immediately removed because its support window is ended.
The qtlocation module is built with `enableParallelBuilding = false` so that the
clipper library will be built before the components which link to it.
kjs now depends directly on pcre. The dependency was previously propagated from
qtbase, which now depends on pcre2.
Use standardized implementation of attribute set extensibility mechanism
instead of manually re-implementing it.
Suggested by @cstrahan at https://github.com/NixOS/nixpkgs/pull/26668.
First of all, we need a newer version of Vc, because at least version
1.1.0 is required for Krita 3.1.3.
Also, qtmultimedia and qtx11extras were missing.
Built and tested successfully on my machine.

The merge of the version bump in
6fb9f89238 didn't take care of our patch
for the hardening mode and thus enabling VirtualBox without also
force-disabling hardening mode will result in a build error.
While the patch is largely identical with the old version, I've removed
one particular change around the following code:
if (pFsObjState->Stat.st_mode & S_IWOTH)
return supR3HardenedSetError3(VERR_SUPLIB_WORLD_WRITABLE, pErrInfo,
"World writable: '", pszPath, "'");
In the old version of the patch we have checked whether the path is
within the Nix store and suppressed the error return if that's the case.
The reason why I did that in the first place was because we had a bunch
of symlinks which were writable.
In VirtualBox 5.1.22 the code specifically checks whether the file is a
symlink, so we can safely drop our change.
Tested via all of the "virtualbox" NixOS VM subtests and they now all
succeed.

The setup hooks for many kdeFrameworks and plasma5 packages were erroneously
running before $outputDev was set. This lead to .dev outputs being propagated
into the user environment.
Without this, a `#include <float.h>` resolves incorrectly. Either the
headers weren't on the include path at all, or they only were for
local, not system, imports.
What's weird is this used to not be a problem. Not sure what other
change in e.g. cc-wrapper would affect this.
I think it's ok to export things which aren't wrapped. The cc-wrapper
can be thought of as responsible for all of binutils and the c
compiler, only wrapping those binaries which are necessary to
interposition---as opposed to all binaries it thinks are relevaant.
Conversely, adding the setup hook to the unwrapped compilers would be
unforunate as hooks are ugly hacks and the compilers themselves take
a long time to rebuild. Better to wholely separate "pure packages" from
hacks.
Packages get --host and --target by default, but can explicitly request
any subset to be passed as needed. See docs for more info.
rustc: Avoid hash breakage by using the old (ignored)
dontSetConfigureCross when not cross building
Eventually we should avoid this "pre-wrapping" and just update those
files in nixpkgs. This mass-rebuild change is best done along with
those needed to reduce the disparity between native and cross (i.e.
making native the "identity cross").
