libpam: extra bounds checking through reallocarray(3).
It appears to be causing brokenness when reporting PAM_* environment
variables. This requires more investigation.
Reported by: lstewart
reallocarray(3) is a non portable extension that originated in OpenBSD.
Given that it is already in FreeBSD's libc it is useful for the cases
where reallocation involves a multiplication.

When sending SIGCHLD informing reaper that a zombie was reparented to
it, we might race with the situation where the previous parent still
not finished delivering SIGCHLD and having its p_ksi structure on the
signal queue. While on queue, the ksi should not be used for another
send.
Fix this by copying p_ksi into newly allocated ksi, which is directly
put onto reaper sigqueue. The later ensures that siginfo for reaper
SIGCHLD is always present, similar to guarantees for siginfo of child.

For such segments, GNU bfd linker writes knowingly incorrect value
into the the file offset field of the program header entry, with the
motivation that file should not be mapped for creation of this segment
at all.
Relax checks for the ELF structure validity when on-disk segment
length is zero, and explicitely set mapping length to zero for such
segments to avoid validating rounding arithmetic.

overly large allocation requests.
When ktrace-ing io, sys_kevent() allocates memory to copy the
requested changes and reported events. Allocations are sized by the
incoming syscall lengths arguments, which are user-controlled, and
might cause overflow in calculations or too large allocations.
Since io trace chunks are limited by ktr_geniosize, there is no sense
it even trying to satisfy unbounded allocations. Export ktr_geniosize
and clamp the buffers sizes in advance.

When we unload we don't hold the pf_rules_lock, so we cannot call rw_sleep()
with it, because it would release a lock we do not hold. There's no need for the
lock either, so we can just tsleep().
While here also make the same change in pf_purge_thread(), because it explicitly
takes the lock before rw_sleep() and then immediately releases it afterwards.
- spelling: "mis-named" should be "misnamed".
- delete spaces interspersed in literal representation of
`struct cam_device` as hard-tabs separate the types and fields.
- Add commas after `e.g.`.

gpart(8) has functionality to change the label of an GPT partition.
This functionality works like it should, however, after a label change
the /dev/gpt/ entries remain unchanged. glabel(8) status output remains

Unfortunately kyua does not omit the path mismatch on failure, so it must be coded

hardware but lack the larger fifos rev 5 hardware should have.
The linux world (where our FDT data comes from) solved this by adding
a new property to pl011 nodes, "arm,primecell-periphid". When this
property is present, its values override the values in the hardware
periphid registers. For pl011 rev 5 hardware with small fifos, they
override the id so that it appears to be rev 4 hardware.
The driver now uses the new property when present. It also continues
to check the device compat string, to handle older fdt data that may
still be in use on existing systems (on RPi systems it is common to
update system software without updating fdt data which is part of the
boot firmware).
