interfaces: multi-dhcp6c support and custom PD association #7647
This splits off rtsold and dhcp6c into separate processes
which frees us from the restrictions of faked iterative IDs
for PD associations. For NA we simply default to 0 now.
I'm not entirely sure why we settled for a single deamon of
dhcp6c back in the day, but there are certianly downsides to
it and I don't see something that wasn't fixed in the meantime
that makes this not work.
Mk/Uses/inotify.mk: Add USES=inotify
FreeBSD 15 includes the inotify system in base, but anything prior to 15
needs the libinotify port. This USES script makes it a little easier to
depend on and use the correct thing.

[MLIR][NFC] Ignore clang-tidy `modernize-use-using` check in C code (#180326)
In the MLIR C API headers, clang-tidy’s `modernize-use-using` check
reports a large number of type definitions that use `typedef`. In my
IDE, this even causes the `typedef` code to be shown as struck through.
However, in this case it is clearly not possible to replace them with
`using`. This PR suppresses the `modernize-use-using` check for the code
inside `extern "C"` blocks.
[AMDGPU] Introduce asyncmark/wait intrinsics
Asynchronous operations are memory transfers (usually between the global memory
and LDS) that are completed independently at an unspecified scope. A thread that
requests one or more asynchronous transfers can use async marks to track their
completion. The thread waits for each mark to be completed, which indicates that
requests initiated in program order before this mark have also completed.
For now, we implement asyncmark/wait operations on pre-GFX12 architectures that
support "LDS DMA" operations. Future work will extend support to GFX12Plus
architectures that support "true" async operations.

[AMDGPU] Asynchronous loads from global/buffer to LDS on pre-GFX12
The existing "LDS DMA" builtins/intrinsics copy data from global/buffer pointer
to LDS. These are now augmented with their ".async" version, where the compiler
does not automatically track completion. The completion is now tracked using
explicit mark/wait intrinsics, which must be inserted by the user. This makes it
possible to write programs with efficient waits in software pipeline loops. The
program can now wait for only the oldest outstanding operations to finish, while
launching more operations for later use.
This change only contains the new names of the builtins/intrinsics, which
continue to behave exactly like their non-async counterparts. A later change
will implement the actual mark/wait semantics in SIInsertWaitcnts.

pcb.h: mark struct pcb to be preserved
There are programs that depend on this structure (e.g. kernel debuggers)
that breaks when the ABI changes.

[RISCV] Add SpacemiT X100 base scheduling model (#178189)
SpacemiT X100 is a 4-issue, out-of-order, RVA23 processor. This patch
introduces the base scheduling model for scalar instructions. The
scheduling model for RVV will be added in a future update.
