[U-Boot] [PATCH] Add "source" command; prepare removal of "autoscr" command

[Peter Tyser <ptyser@xes-inc.com>]

The changes look good to me.  2 comments below:

I'd vote to change autoscr's help messages to something letting end
user's know that the command is deprecated and being replaced by the
"source".  Eg something like:

+ autoscr, 2, 0, do_source,
+ "DEPRECATED - see 'source' command",
+ "DEPRECATED - see 'source' command"

Most U-Boot user's are more likely to see this than the
feature-removal-schedule.txt in the source code.

There's an out of place newline here.
