linker: Reset DMAP protections in link_elf_unload_file()
On x86, when a preloaded kernel module is unloaded, we free the backing
(physically contiguous) pages. The ET_REL linker will have adjusted
protections on segments of the preloaded file, which updates the direct
map, so the original protections must be restored when unloading the
module.
Previously this was handled in kmem_bootstrap_free(), but there is no
apparent reason not to handle this within the kernel linker. Moreover,
we were not resetting permissions in the kernel map on arm64.

pf: Avoid taking the pf rules write lock in a couple of ioctls
The DIOCGETRULES ioctl handlers has taken the write lock ever since
fine-grained locking was merged to pf, but I believe it's unneeded. Use
the read lock instead.
DIOCGETRULENV takes the write lock as well but I believe this is only
required when clearing rule counters. Acquire the read lock if that is
not the case.

pf: Fix state handling when ICMP packets are diverted
Commit 66f2f1c83247 ("pf: handle divert packets") missed a case that I
happened to hit while testing something.
Add a regression test for the ICMP case, based on the existing test.
Fix a buglet in the existing test (missing whitespace after "[").

ifconfig: Fix the -L flag when using netlink
By default, when ifconfig shows a v6 address derived from a
router-advertised prefix, it shows the initial preferred and valid
lifetimes. When -L is specified, it is supposed to show the remaining
lifetimes, but this was broken in the conversion to netlink.
Fix that, and add a regression test which validates ifconfig output
before and after a short-lived address expires.
