mmp: tell a failed uberblock claim apart from remote activity
When the claim could not write to every device the config expects
present, spa_activity_check_claim() replaced the error from
mmp_claim_uberblock() with EREMOTEIO, so an operator whose peer died
together with its mirror legs was told another host holds the pool,
which sends them looking for a host that is not there.
Report the cause instead. A shortfall has two causes worth telling
apart, so mmp_claim_uberblock() now counts the writes it issues
alongside the ones that succeed. A leaf the config expects present but
which cannot be written is never issued one, so too few issued means a
device is absent, which persists across retries and is what
"zhack mmp reclaim" recovers; that returns ENODEV. Enough issued but
too few good means the writes reached present devices and failed, which
a retry may clear; that stays EIO. The issued count is gated exactly as
the good count is so the two describe the same set of leaves.
Both get a case in spa_ld_activity_result() and both still return

ZTS: add coverage for zhack mmp reclaim
Six scenarios: a stranded pool is recovered and the claim then accepts
it, a live host sharing a leg is still refused, both top-level vdevs
are counted after a recovery, a pool without multihost is left alone,
a log vdev leg is not touched, and a raidz member is not touched.
Every recovery assertion re-imports as a third hostid. zhack exports
cleanly under its own hostid, so importing again as the same host
takes the exported-and-matching-hostid path, skips the activity check
entirely, and would leave the claim unexercised and the test vacuous.
The assertions read req_writes and good_writes from the claim's own
dbgmsg line, which 20176224e added. That is the only observable of
the claim arithmetic, at the cost of coupling the test to a debug
message this change does not control.
mmp_pool_destroy() used a bare "pgrep zhack", which matches any
process whose name merely contains zhack. A ksh script named

zhack: add "mmp reclaim" to recover a pool stranded by MMP
When a host fails together with the mirror legs attached to it, the
surviving labels still describe those legs as present, so the MMP
uberblock claim keeps demanding a write to every one of them and no
later import can satisfy it. The pool cannot be imported by any host
again.
Add "zhack mmp reclaim", which imports once with the claim's required
write count relaxed for the mirror legs this host cannot open, marks
those leaves offline so that the ordinary imports which follow
succeed, and exports.
The relaxation is confined to userspace. mmp_claim_relaxed is
declared under #ifndef _KERNEL, and module/Kbuild.in builds the module
with -D_KERNEL, so the flag cannot exist in a kernel module. libzpool
does not define _KERNEL and so gets the check. This follows the
zfeature_checks_disable pattern zhack already uses around the same
import, and is stronger, since that flag does exist in the kernel.

[libc] Implement expected<void, E> and use it in internal utilities (#215020)
Add the expected<void, E> partial template specialization to support
functions that return an error on failure and nothing on success,
matching std::expected<void, E>.
I've used this to resolve a TODO in if_nameindex and converted a few
other simple internal functions (pwd_utils::open/close,
update_from_seconds, stat_via_statx).

[scudo] Remove malloc_enable_child from API. (#215439)
The malloc_enable_child does not need to be a public API, instead move
the function to be static and reference it that way.
[RISCV] Avoid pre-RA Zilsd pairs with same src/dst registers (#215575)
The pre-RA Zilsd optimizer previously allowed a special case for stores
where both source operands were the same vreg if that vreg was defined
by COPY $x0. This assumes register allocation will preserve the value as
x0, but that is not guaranteed. The vreg can be allocated to a normal
GPR, producing an invalid pair.
