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.

Update tcpdump to 4.9.0.

It fixes many buffer overflow in different protocol parsers, but none of
them are critical, even in absense of Capsicum.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.
