[PATCH] Use extcmd to handle bsd arguments.

[Vladimir 'phcoder' Serbinenko]

Hello. Currently bsd loaders inspects argv[1] for boot options but the
treat argv[1] as if it always was prefixed by dash ('-') and
completely ignores options in argv[n], n>1. This leads to unexpected
results like
freebsd /kernel verbose
is parsed like verbose ('v'), dfltroot ('r') and single ('s')
freebsd /kernel -v -s
is parsed only like verbose and not verbose and single.
Additionally help shows no information about these options. This patch
delegates option parsing to lib/arg.c and so achieves good option
passing, GNU-style options support and provides help. Unfortunately
booting with some options has no noticeable effect so I couldn't
document what they do
