r355990:
MFV r355890:

Fix libpcap issue #893: check for invalid IPv4 addresses.

This fixes errors such as:

tcpdump -i lagg0 net 999.999.999.999

This was originally discovered on a Red Hat 7.7 server and verified
to also be a bug on FreeBSD.

MFC r326613: Update tcpdump to 4.9.2

It contains many fixes, including bounds checking, buffer overflows (in
SLIP and bittok2str_internal), buffer over-reads, and infinite loops.

One other notable change:
Do not use getprotobynumber() for protocol name resolution.
Do not do any protocol name resolution if -n is specified.

resolve merge conflicts and update for proper build; including:

o print-fr.c returned to code on vendor branch
o remove pmap_prot.h include from print-sunrprc.c
o remove gcc/i386-specific ntoh* write-arounds from tcpdump-stdinc.h

Merge of tcpdump 3.8.3 from tcpdump.org, with the following caveats:

print-atm.c no longer performs special handling for FORE headers; these
can no doubt be re-added at a later date.

print-fr.c is effectively a no-op.

print-llc.c has had the default_print_unaligned() call removed as
tcpdump no longer defines this function, however the prototype is still
present. Suggest we roll in a diff to use print_unknown_data().

Merge tcpdump 3.6.2

* Buffer-safe string function cleanup. There are a couple of strcpy()
and strcat()s which would be more difficult to fix, but I think they're
safe anyway.
* Don't crash at runtime by overflowing a buffer with constant data in
print-icmp.c on a long hostname.
* Don't overflow a static buffer by trying to decode an AFS ACL into a buffer
which is way too small for it.

Merge tcpdump 3.5

Merge tcpdump 3.3.
The print_nfs.c changes are pretty extensive; this is partially because
LBL did a lot of cleanup and partially because I removed lots of
pointless changes away from the LBL style.
