This is neither POSIX compliant nor what the implementation does.

The current localedef simply assumes that the locale headers on build system
are compatible with those on the target system which is not necessarily true.
It generally works on FreeBSD (as long as we don't change the locale headers),
but Linux and macOS provide completely different locale headers.
This change adds new bootstrap headers that namespace certain xlocale
structures defined or used by in the headers that localdef needs.
This is required since system headers *must* be able to include the "real"
locale headers for printf(), etc., but we also want to access the target
systems's internal locale structures.

This problem will be fixed in the next commit.
Generate libpmc_events.c in a temporary file first and only overwrite it

It keeps recalculated way more often than it is needed.
Provide a routine (fdlastfile) to get it if necessary.
Consumers may be better off with a bitmap iterator instead.
The code in nfscl_dofflayout() loops when a flexible file layout server
provides a small write data limit (no extant server is known to do this).
If/when it looped, it erroneously reused the "drpc" argument for the
mirror worker thread, corrupting it.
This patch fixes the problem by only using the calling thread after the
first loop iteration.
Found during testing by simulating a server with a small write size.
Since no extant pNFS server is known to provide a small write size,
this fix it not needed in practice at this time.

I made an attempt to fix this in r362978, but all it really did was
confine the issue to the $MACHINE_CPUARCH == "riscv" case. The real
problem is that LINKER_FEATURES is not defined here, so bsd.linker.mk
needs to be included.
This error with cleandir only occurs when META_MODE is disabled, which
explains why it was missed by both CI and myself.
Note that this effectively reverts r362978.

Stop using smp_ipi_mtx to protect global shootdown state, and
move/multiply the global state into pcpu. Now each CPU can initiate
shootdown IPI independently from other CPUs. Initiator enters
critical section, then fills its local PCPU shootdown info
(pc_smp_tlb_XXX), then clears scoreboard generation at location (cpu,
my_cpuid) for each target cpu. After that IPI is sent to all targets
which scan for zeroed scoreboard generation words. Upon finding such
word the shootdown data is read from corresponding cpu' pcpu, and
generation is set. Meantime initiator loops waiting for all zeroed
generations in scoreboard to update.
Initiator does not disable interrupts, which should allow
non-invalidation IPIs from deadlocking, it only needs to disable
preemption to pin itself to the instance of the pcpu smp_tlb data.
The generation is set before the actual invalidation is performed in
handler. It is safe because target CPU cannot return to userspace
before handler finishes. In principle only NMI can preempt the
handler, but NMI would see the kernel handler frame and not touch
not-invalidated user page table.
Handlers loop until they do not see zeroed scoreboard generations.
This, together with hardware keeping one pending IPI in LAPIC IRR
should prevent lost shootdowns.
Notes.
1. The code does protect writes to LAPIC ICR with exclusion. I believe
this is fine because we in fact do not send IPIs from interrupt
handlers. More for !x2APIC mode where ICR access for write requires
two registers write, we disable interrupts around it. If considered
incorrect, I can add per-cpu spinlock around ipi_send().
2. Scoreboard lines owned by given target CPU can be padded to the
cache line, to reduce ping-pong.
