Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Linux requires -D__dead2= and -D__unused= to get rid of the
sys/cdef.h-isms in the make source. The variant of linux I tried it
on doesn't have arc4random, so -Darc4random=random too.

Use a clever definition of __FBSDID to allow building on !FreeBSD systems.

Use the name of the default shell instead of a numeric index to select
the default shell.

Idea from: DragonFlyBSD

Move all the remaining list functions into one C-file and remove
double documentation comments. Remove the 3rd clause (from 4) of the
BSD license because these files have only the UCB copyright.

Include -DDEFSHELL=1 in Makefile.dist so people boostrapping will
have a sane default.

Also add $FreeBSD$ while I'm here.
