- Implement bus_map/unmap_resource pulling bits from the previous
ofw_pcib_activate/deactivate_resource. One difference here is that
the bus_unmap_resource implementation uses bus_space_unmap instead
of pmap_unmapdev as a complement to the existing use of bus_space_map.
- Use bus_generic_rman_* in various routines for memory and I/O port
resources.
- Use pci_domain_* for PCI_RES_BUS in
ofw_pcib_activate/deactivate_resource.

Previously it failed to compile since the macro passed too many
arguments to the function. Fix by adding the bus handle to the
function and adding an implementation that calls pmap_unmapdev.

- Stop assuming that the breakpoint size is one byte.
- Avoid referencing the "rip" field in machine-independent code, use a
helper.

It's awkward to have separate tables for information which is logically
connected. Merge the gdb_regset[] and gdb_regsize[] arrays and update
gdb_read_regs() to cope with the result. This makes the addition of
arm64 support a bit cleaner.

bsdlabel is intended to support up to 20 partitions, but the disklabel
struct has a d_partitions array with only BSD_NPARTS_MIN (8) entries.
Previously, an attempt to operate on a bsdlabel with more than eight
partitions resulted in a buffer overflow.
As a stopgap limit bsdlabel to 8 partitions until this is fixed
properly.

While there are no inherent limits to the number of exporters we're
likely to scale rather badly to very large numbers. There's also no
obvious use case for more than a handful. Limit to 128 exporters to
prevent foot-shooting.

bpfattach() is called in wg_clone_create(), but the bpfdetach() is
missing from wg_close_destroy(). Add the missing bpfdetach() to avoid
leaking both the associated bpf bits as well as the ifnet that bpf will

If we're applying NPTv6 we pass a packet with a modified source and/or
destination address to the network stack.
If that packet then turns out to be larger than the MTU of the sending
interface the stack will attempt to generate an icmp6 packet-too-big
error, but may fail to look up the appropriate source address for that
error message. Even if it does, pf would still have to undo the binat
operation inside the icmp6 packet so the sending host can make sense of
the error.
We can avoid both problems entirely by having pf also perform the MTU
check (taking the potential refragmentation into account), and
generating the icmp6 error directly in pf.

The usual use case in 2024 for newfs_msdosfs is creating filesystems on SD cards
for older hardware. In most tutorials, they call the cluster size "allocation
size". Therefore, add a small note next to cluster size that it is also called
allocation size, and add an example for how to do this.
