[Crash-utility] sial output redirection

[Denman, Robert]

Luc,
The following patch will allow the output of SIAL commands to be
redirected to a file or pipe.  I did not handle all cases supported by
crash (e.g. multi-pipes), only simple output redirection.  Would you
please consider this change or something like it in the next release?
Thanks.
