manpages: Remove telnetd references

Mostly remove from the SEE ALSO section, adding a mention of the port
where not removed. Elsewhere, remove as appropriate and change from .Xr
to .Nm where a mention of telnetd continues to make sense (or removing
it would require significant reworking of the surrounding text).

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.
