[PATCH] uml: add mconsole_reply variant with length param 

This is needed for the console output patch, since we have a possibly
non-NULL-terminated string there.  So, the new interface takes a string and a
length, and the old interface calls strlen on its string and calls the new
interface with the length.

There's also a bit of whitespace cleanup.
