Most ATM support was removed prior to FreeBSD 12. The netgraph support
was kept as it was less intrusive, but it is presumed to be unused.

It's possible for Xen to switch the video mode set by the boot loader,
so that the information passed in the kernel metadata is no longer
valid. Fetch the video mode used by Xen using an hypercall and update
the medatada for the kernel to use the correct video mode.

This change adds the "default" parsers of _all_ route/link attributes

It removes the need to declare similar parsers in the userland applications,

Some routing socket defines (`RTM_` and `RTA_` ones) clash with the ones
used by the the Netlink.
As some rtsock definitions like interface flags or route flags are used in
both netlink and rtsock, provide a convenient way to include those without
running into the define collision.

rc.d/hostid_save saves a UUID generated by rc.d/hostid in /etc/hostid.
Store the same UUID, without hyphens, in /etc/machine-id. The hypĥens
are removed with a shell function because hostid_save runs before file
systems are mounted so other tools may not be available yet.
This eliminates some duplication between hostid and machine-id and for
virtual machines machine-id now contains the UUID configured in the
hypervisor like it does on Linux.

When compiling current on arm64, it breaks since LA_UNLOCKED is
undefined. This was in turn caused by the mutex code aliasing
it as MA_NOTOWNED.
Add <sys/lock.h> so the macro is defined.
Building with -DMSDOSFS_DEBUG failed due to a format mismatch and

Started seeing the following after updating to VMware ESXi 8.0:
pcib2: <ACPI Host-PCI bridge> on acpi0
pcib2: could not evaluate _ADR - AE_NOT_FOUND
pci2: <ACPI PCI bus> on pcib2
vmx0: <VMware VMXNET3 Ethernet Adapter> ...
The virtual NIC works fine, and the code comment suggests that
missing _ADR is not something fatal, skip printing the message
if status is AE_NOT_FOUND.

Have to add a check that the computed cylinder group size does not
exceed the block size of the filesystem.
It is also necessary to validate additional parameters when a
superblock is going to be used in read-only mode if its supplementary
information is going to be read in to ensure that the size and
location of the supplementary information is valid. Also when a
warning is raised let it be accepted, but bound the flagged field
to the value checked by the warning.
No legitimate superblocks should fail as a result of these changes.

The assertions added in commit b0ccf53f24 ("inpcb: Assert against
wildcard addrs in in_pcblookup_hash_locked()") revealed that protocol
layers may pass the unspecified address to in_pcblookup().
Add some checks to filter out such packets before we attempt an inpcb
lookup:
- Disallow the use of an unspecified source address in in_pcbladdr() and
in6_pcbladdr().
- Disallow IP packets with an unspecified destination address.
- Disallow TCP packets with an unspecified source address, and add an
assertion to verify the comment claiming that the case of an
unspecified destination address is handled by the IP layer.

epairs currently shuttle all transmitted packets through a single global
taskqueue thread. To hand packets over to the taskqueue thread, each
epair maintains a pair of ring buffers and a lockless scheme for
notifying the thread of pending work. The implementation can lead to
lost wakeups, causing to-be-transmitted packets to end up stuck in the
queue.
Rather than extending the existing scheme, simply replace it with a
linked list protected by a mutex, and use the mutex to synchronize
wakeups of the taskqueue thread. This appears to give equivalent or
better throughput with >= 16 producer threads and eliminates the lost
wakeups.
