Casper services expect that the first 3 descriptors (stdin/stdout/stderr)
will point to /dev/null. Which Casper will ensure later. The Casper
services are forked from the original process. If the initial process
closes one of those descriptors, Casper may reuse one of them for it on
purpose. If this is the case, then renumarate the descriptors used by
Casper to higher numbers. This is done already after the fork, so it
doesn't break the parent process.

Instead of requiring all implementations of vfs_quotactl to unbusy
the mount for Q_QUOTAON and Q_QUOTAOFF, add an "mp_busy" in/out param
to VFS_QUOTACTL(9). The implementation may then indicate to the caller
whether it needed to unbusy the mount.
Also, add stbool.h to libprocstat modules which #define _KERNEL
before including sys/mount.h. Otherwise they'll pull in sys/types.h
before defining _KERNEL and therefore won't have the bool definition
they need for mp_busy.

When collecting kernel stacks for a target process, if the process
adds a thread between the two calls to sysctl, ignore the additional

We know that snapshot is already stale, but it could still be stale
even with a more complex fix to reallocate and retry, so such a fix
is hardly worth the effort.

On x86, the pmu_events table is the source of truth for finding
supported events. However, events not found there may still be present
in the kernel's static event tables. For example, the pmc.soft(3) events
will never be available from pmu-events.
Update pmc_allocate() to search the legacy event tables if
pmc_pmu_pmcallocate() fails to return a result. This allows both event
sources to be consulted before giving up, thus restoring pmc.soft(3) and
pmc.tsc(3) on x86.

This logic was added for handling some of the complicated relationships
between events and x86 CPU models. Since that logic has been mostly
removed from libpmc(3) in favor of pmu-events, this no longer serves
much of a purpose. Mapping CPU types to event tables is already handled
by the switch statement in pmc_init().

When parsing the nvlist for a struct pf_addr_wrap we unconditionally
tried to parse "ifname". This broke for PF_ADDR_TABLE when the table
name was longer than IFNAMSIZ. PF_TABLE_NAME_SIZE is longer than
IFNAMSIZ, so this is a valid configuration.
Only parse (or return) ifname or tblname for the corresponding
pf_addr_wrap type.
This manifested as a failure to set rules such as these, where the pfctl
optimiser generated an automatic table:
