Nuke ascii2addr() and addr2ascii(). They have no consumers anywhere

in FreeBSD, and originated from INRIA IPv6.

Stub out netstat reference to addr2ascii() I mistakenly introduced.
Update misleading man page sections.

Merge NetBSD's getnameinfo() AF_LINK extensions for a portable way to
print link-layer addresses given a sockaddr_dl(), minus the IEEE 1394
bits which don't map directly to our code.

Obtained from:	NetBSD (getnameinfo.c)
Discussed on:	current (March 2006)
