This adds two new rules named create-packages-kernel-repo and
create-packages-world-repo.
The goal of those rules is to create the {kernel,world} packages and
after that the repository.
It helps a lot for developing with pkgbase by adding the dev machine
repository created by those rules on top of the official pkgbase one.

This is a preparation for adding dtrace hooks in a follow-up commit,
which are missing in the code path, where packets are directly queued
to the tcpcb. The dtrace hooks expect the fields to be in host byte
order. This only applies when TCP HPTS is used.
No functional change intended.

[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.

The RFC6675 pipe calculation (sack.revised, enabled
by default since D28702), uses outdated information,
while the previous default calculated it correctly
with up-to-date information from the incoming ACK.
This difference can become as large as the receive
window (not the congestion window previously),
potentially triggering a massive burst of new packets.

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.

I observed the problem on a system with fairly old and, apparently,
buggy EFI implementation. A list of boot devices had an invalid
trailing entry. efidp_size() for that entry returned zero, which means
that the code got stuck looping on that entry.
The rest of the sound system supports 7+1 maximum and is not aware of 8+0.
I believe that these messages are caused by 8+0:
kernel: feeder_init(0xfffff801f935d680) on feeder_matrix returned 22
kernel: pcm0: feeder_build_matrix(): can't add feeder_matrix
This should disable allocation of the second per-CPU principal buffer
which is never used. This will also enable additional asserts
for buffers that are never switched.
For example, shutdown_panic wants to produce some output and maybe take
some input before a system is actually reset.
The change should only make difference for the case of system reset
(reboot), poweroff and halt should not be affected.
The change makes difference only if hw.acpi.handle_reboot is set. It
used to default to zero until r213755 / ac731af567.
First of all and unlike I2C, it's not the master that dictates how many
bytes to read in block read operation. It's the device that informs the
master how many bytes it's sending back.
Thus, for ichsmb_bread() the count parameter is purely an output
parameter. The code has been changed to reflect that.
The sanity checking of the response length is now done once it (the
first byte of the response) is received.
While here, handling of ICH_HST_STA_FAILED status bit has been added.
Plus some code style improvements and some new code comments in the
vicinity of the changed code.
That is, wd_shutdown_countdown value is ignored when halting.
A halted system should remain halted for as long as needed until
a power cycle, so the watchdog should not reset the system.
Power off or reset may be activated either by low or high signal or by an
edge. So, try everything.
Also, the driver now supports DTS properties for timings.
Finally, the driver does not change the pin configuration during attach.
It is assumed that the pin is already in a state that does not trigger
the power event (otherwise we wouldn't be running).
Fall-through to non-FDT probe code if no matching device node is found.
While here, fix indentation of the switch statement.
Also, make the device description for the hints-based attachment the
same as for FDT attachment.

On several systems we've noticed that when NTB link goes down, the
Physical Layer User Test Pattern registers we use as additional
scratchpad registers (that is explicitly allowed by the chip specs)
become read-only for about 100us. I see no explanation for this in
the chip specs, neither why it was not seen before, may be a race.
Since we do need these registers, workaround it by repeating writes
until we succeed or 1ms timeout expire.
