linuxkpi: add uuid_t and helpers
linux/uuid.h has only the guid_t family. Add uuid_t, next to guid_t,
with uuid_equal(), uuid_copy(), import_uuid() and export_uuid(),
mirroring the guid_ versions.
Used by drm/virtio for dma-buf UUID export.

linuxkpi: add pci_is_vga()
Returns true for a VGA-compatible display controller and for the
pre-PCI 2.0 VGA class (base 0x00, subclass 0x01), as Linux's
pci_is_vga() does. Used by drm/virtio to decide whether to remove
the firmware framebuffer on virtio-vga.

linuxkpi: add strncpy_from_user()
Same semantics as Linux: returns the string length without the NUL,
count if the string was truncated, or -EFAULT. Implemented with
copyinstr(9). Unlike linux_copyin() it does not translate the remapped
ioctl argument window; its user, drm/virtio, passes a pointer taken
from the ioctl payload, so that is not needed.

acpi_apple: make the device mode a typed enum
The two mode values were spelled as bit flags, but a device is exactly
one of the two and the dispatch compared the field for equality.
Turned them into an enum, type the softc field with it, and dispatch with
a switch that lists every value
No functional change.

acpi_apple: rename source files to match the driver name
The driver, module, kernel option and manual page are all named
acpi_apple, but the sources lived in sys/dev/apple_acpi/ with an
apple_ prefix. Every other vendor ACPI driver in the tree uses the
acpi_<vendor> form for both the directory and the file names.
No functional change.

multimedia/openh264: link library as originally intended
We carried this patch since importing openh264 into the ports tree,
but at this time it results in weird linkage.
The original reasoning behind this patch can't be reconstructed beyond
the short comment in the patch file.
Without the patch, the library looks much more sane.

lang/v8: update to 15.5.35.25
- Initialize the attribute object before passing it to
pthread_attr_get_np() in PartitionAlloc's GetStackTop(), which
FreeBSD requires.
lang/v8-beta: update to 15.7.112 (Chrome 157 beta)
- Update the dependency pins from DEPS and the Temporal crates to the
versions in Chromium's third_party/rust.
- Adapt the pkg-config.py and PartitionAlloc stack patches to upstream
changes. Initialize the attribute object before passing it to
pthread_attr_get_np(), which FreeBSD requires.
- libclang's Python bindings before LLVM 21 pass non-Cursor operands
such as None to clang_equalCursors(), which metagen now relies on
working. Extend the existing shim with LLVM 21's Cursor.__eq__.
[clang][CodeGen] Fix assertion failure for new T[SIZE_MAX] with array cookie (#232570)
Fixes #232250.
`EmitCXXNewExpr` asserts that `allocSize == allocSizeWithoutCookie` if
and only if no array cookie is needed. The "only if" direction does not
always hold.
`EmitCXXNewAllocSize` replaces the allocation size with an all-ones
value when the size computation overflows, so that `operator new` fails.
If the count times the element size is already all-ones and adding the
cookie then overflows, both values are the same uniqued constant even
though a cookie is present. For example, on i386:
struct S { ~S(); };
void f() { new S[0xFFFFFFFFu]; }
Here `sizeof(S) == 1`, the cookie is 4 bytes, and `0xFFFFFFFF + 4`
overflows, so the assertion fired. This can't happen on 64-bit targets

tcp/rack: reject wma_divisor values <= 0
The net.inet.tcp.rack.measure.wma_divisor sysctl is the divisor
of the goodput weighted moving average used when the dynamic
goodput multiplier is enabled. Setting it to 0 panics the kernel.
Make the variable and the sysctl unsigned, reject 0 and values
above INT32_MAX.
