stge_attach() could fail at line 464, sc->sc_spec remains NULL when
calling stge_detach(), thus bus_release_resources() at line 704 will
trigger null pointer dereference. We need to check the nulliness before
calling bus_release_resources().

The props feature to this API was added as a "just in case", with no
planned consumer. It turns out that it was implemented incorrectly,
tapping out props for the BE root (BE's parent) rather than the BE
itself in all cases.
Fetch properties for the dataset that's actually mounted at the queried
path.

Historically 32-bit Linuxulator under amd64 emulated the real i386
behavior. Since 3d8dd983 the old i386 Linux world can't be used under
amd64 Linuxulator as it don't know anything about amd64 machine (which
is returned now by newuname() syscall). So, add a knob to allow to swith
the behavior and use i386 Linux binaries on amd64.
Set knob to the new behavior as I think this is common to the modern
Linux distros.

Compiling another driver on i386 revealed two problems:
- ieee80211_tx_info.status.status_driver_data space needs to be
calculated. While a pointer is 32bit vm_paddr_t is 64 bit on i386
so we didn't fit more than one of these in but needed more space.
- the arguments to ieee80211_txq_get_depth() are expected to
unsigned long and not uint64_t.
No user noticable changes.

"ifconfig -g groupname" prints a list of interface names,
which could be confusing, because it differs from
the behavior of "ifconfig -a -g groupname".
While here, add two examples showing the difference between
"ifconfig -a -g groupname" and "ifconfig -g groupname".

In the search for contiguous pages, as each page segment is examined,
check to see if the free list set for the next page segment differs
from the set for the current segment, and avoid a pointless search if

The limit may later be updated by the "set limit" directive in pf.conf.
UMA does not permit a limit to be set on a zone after any items have
been allocated from a zone.
Other UMA zones used by pf do not appear to be susceptible to this
problem: they either set a limit at zone creation time or never set one
at all.
