Polish the syslog messages to contain readily useful information.
Behavior of capability 'priority' is inconsistent with what is done for
all other contexts: 'umask', 'cpumask', resource limits, etc., where an
absence of capability means to inherit the value. It is currently
preserved for compatibility, but is subject to change on a future major
release.

Simplify the code and make it more coherent (umask was the only context
setting not modified by setlogincontext() directly).
Preserve the current behavior of not changing the umask if none is
specified in the login class capabilities database, but without the
superfluous umask() dance. (The only exception to this is that
a special value no user is likely to input in the database now stands
for no specification.)
If some user has a 'umask' override in its '~/.login_conf', the umask
will still be set twice as before (as is the case for all other context
settings overriden in '~/.login_conf').
Log a warning in case of an invalid umask specification.
This change makes it apparent that the value of LOGIN_DEFUMASK doesn't
matter. It will be removed in a subsequent commit.

[libc++] Fix filesystem::remove_all() on FreeBSD (#79540)
remove_all_impl() opens the target path with O_NOFOLLOW, which fails if
the target is a symbolic link. On FreeBSD, rather than returning ELOOP,
openat() returns EMLINK. This is unlikely to change for compatibility
reasons, see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214633 .
Thus, check for EMLINK as well.

When we route-to the state should be bound to the route-to interface,
not the default route interface. However, we should only do so for
outbound traffic, because inbound traffic should bind on the arriving
interface, not the one we eventually transmit on.
Explicitly check for this in BOUND_IFACE().
We must also extend pf_find_state(), because subsequent packets within
the established state will attempt to match the original interface, not
the route-to interface.

pfil hooks (i.e. firewalls) may pass, modify or free the mbuf passed
to them. (E.g. when rejecting a packet, or when gathering up packets
for reassembly).
If the hook returns PFIL_PASS the mbuf must still be present. Assert
this in pfil_mem_common() and ensure that ipfilter follows this
convention. pf and ipfw already did.
Similarly, if the hook returns PFIL_DROPPED or PFIL_CONSUMED the mbuf
must have been freed (or now be owned by the firewall for further
processing, like packet scheduling or reassembly).
This allows us to remove a few extraneous NULL checks.

This difference can become as large as the receive

If the header that we add to the packet's size is 0 % 4 and we're
strictly aligning, then we need to adjust where we store the header so
the packet that follows will have it's struct ip header properly
aligned. We do this on allocation (and when we check the length of the
mbufs in the lro_nomrg case). We can't just adjust the clustersz in the
softc, because it's also used to allocate the mbufs and it needs to be
the proper size for that. Since we otherwise use the size of the mbuf
(or sometimes the smaller size of the received packet) to compute how
much we can buffer, this ensures no overflows. The 2 byte adjustment
also does not affect how many packets we can receive in the lro_nomrg
case.
