9p: parse lines in rdwr command
Use bio(3) to read at most one line of input per iteration, even if there is more than one line available in the input buffer. This makes it easier to interact with line-oriented ctl files like that of factotum(4) from shell scripts, without the need to control when and how much data is flushed to a pipe.
Trivial changes: whitespace and modes.
Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>
