Replaces panic with a warning message to allow kernel continue
when no bootp eligible network interfaces are found.
This avoids having to build a custom kernel when using a local root
file system on targets like powerpcspe that expects bootp/NFS by
default.

dev_alloc_skb() comapred to alloc_skb() reserves some headroom
at the beginning of the skb which is used by drivers.
Split the code for the two cases and reserve NET_SKB_PAD space,
which should at least be 32 octets.

Following up on fb8c87b4f3, which was
supposed to go into all supported branches, increase ieee80211_scanparams
status field from 8bit to 32bit (enum size) and add a dedicated error
code for Mesh ID.

The driver parsed the table to update the relevant resource map
registers, but failed to write the new register value after computing
it.

Since physical memory management is now handled by subr_physmem.c, the
need to keep this global array has diminished. It is not referenced
outside of early boot-time, and is populated by physmem_avail() in
pmap_bootstrap(). Just allocate the array on the stack for the duration
of its lifetime.
The check against physmap[0] in initriscv() can be dropped altogether,
as there is no consequence for excluding a memory range twice.

The page size may be dynamically selected on boot. Have the
coredump_phnum test helper ask the kernel for the correct value.

We forgot to free the nvlist (and packed nvlist) on success.
While here start using the ERROUT macro to clean up error handling, and
to add SDTs for better debugging.

The nvlist is allocated in pf_keth_rule_to_nveth_rule(). There's no need
to allocate one in the calling function. Especially not as we overwrite
the pointer to the new nvlist with the one allocated by
pf_keth_rule_to_nveth_rule(), leaking memory.

These options use the CONS_SCRSHOT ioctl to capture the contents of the
current console, which is not yet supported by vt(4). Disable the
options when vt(4) is in use rather than emitting a possibly confusing
error message.
This change should be reverted if CONS_SCRSHOT is implemented for vt(4).

- Mark a value only used in debug traces as unused.
- Remove variables only used for device register reads with
side-effects with void casts on the read.
