printk: rename LOG_NEWLINE and tidy upreview/more-printk-flags

Rename LOG_NEWLINE to be LOG_COMPLETE, so it makes more sense in the
context of a log record (or a string of them) rather than how a
record gets formatted.

Add a block of commentary explaining how the log flags indicate that
consecutive log records should be treated as a single logical log
entry.

Do some other tidying of the code now that a lot of the former flags
complexity has been eliminated.
