- Support partial writes to IO handles.
printf can turn a single print statement into multiple, fragmented
writes to the IO handle. Add a "commit" method to signal that the
multiple partial writes have completed.

- [lib][memlog] Do not expose memlog data until the writer is done.
Due to how LK's printf works, a single print statement may result in
multiple write calls to the memlog. A second thread reading the memlog
can observe each write as it occurs. This can result in corrupted output
if the observer treats each write as a separate logging event.
To work around this issue, a seperate "commit" function was added to
signal that a write is complete and that memlog should expose the
recently written data.
