pfctl -ss printed state levels for ICMPv6. Disable this the same

panic seen with some some icmp types in icmp error message payloads.
Obtained from: OpenBSD
Stricter state checking for ICMP and ICMPv6 packets: include the ICMP type
in one port of the state key, using the type to determine which
side should be the id, and which should be the type. Also:
- Handle ICMP6 messages which are typically sent to multicast
addresses but recieve unicast replies, by doing fallthrough lookups
against the correct multicast address. - Clear up some mistaken
assumptions in the PF code:
- Not all ICMP packets have an icmp_id, so simulate
one based on other data if we can, otherwise set it to 0.
- Don't modify the icmp id field in NAT unless it's echo
- Use the full range of possible id's when NATing icmp6 echoy
Difference with OpenBSD version:
- C99ify the new code
- WITHOUT_INET6 safe

In blk_write(), code verifies that ptr and pa cannot be non-zero
simultaneously. The later check for the page-alignment of the ptr
argument never triggers due to pa != 0 always implying ptr == NULL. I
believe that the intent was to ensure that physicall address passed is
page-aligned, since the address is (temporary) mapped for the duration
of the page write.
Clear the progress_track.visited fields when starting minidump. If
minidump is restarted or taken second time during the system lifetime,
progress is not printed otherwise, making operator suspectible to the
dump status.

The future plan is to split most of non-kernel parts of

and replace example outputs with output from lockstat on FreeBSD, since
lockstat's output contains stack traces.
This change also removes some examples that don't seem to work properly on
FreeBSD. The examples should be re-added when lockstat is fixed.

space compared to the old way of hardcoding the end address as 0xE0000000.
Also, pre-map most of the SoC's common memory-mapped devices using 1MB
section mappings so that all device access uses just a few TLB entries.
Graphics devices aren't mapped this way yet, but probably should be.
To provide this new functionality without pasting identical code into
multiple imxNN_machdep.c files, rework the imx machdep code so that
things common to the whole family of SoCs are in a new imx_machdep.c file.
The rewritten imxNN_machdep.c files contain just things specific to an
individual SoC.

BIO_new_mem_buf takes a void* buf, but internally it never modifies the
buf. It assigns the buffer to another pointer and then marks it as
read-only. So deconsting it should be safe here.
