sbuf(9): Add sbuf_nl_terminate() API

The API is used to gracefully terminate text line(s) with a single \n. If
the formatted buffer was empty or already ended in \n, it is unmodified.
Otherwise, a newline character is appended to it. The API, like other
sbuf-modifying routines, is only valid while the sbuf is not FINISHED.

device_printf: Use sbuf for more coherent prints on SMP

device_printf does multiple calls to printf allowing other console messages to
be inserted between the device name, and the rest of the message. This change
uses sbuf to compose to two into a single buffer, and prints it all at once.

It exposes an sbuf drain function (drain-to-printf) for common use.

Update documentation to match; some unit tests included.

Implement simple record boundary tracking in sbuf(9) to avoid record splitting
during drain operations. When an sbuf is configured to use this feature by way
of the SBUF_DRAINTOEOR sbuf_new() flag, top-level sections started with
sbuf_start_section() create a record boundary marker that is used to avoid
flushing partial records.

Implement sbuf_prf(), which takes an sbuf and outputs it
to stdout in the non-kernel case and to the console+log
in the kernel case. For the kernel case it hooks the
putbuf() machinery underneath printf(9) so that the buffer
is written completely atomically and without a copy into
another temporary buffer. This is useful for fixing
compound console/log messages that become broken and
interleaved when multiple threads are competing for the
console.
