Message:

Convert kernel console writing to byte arrays

More buffer per buffer (the original char32_t buffer takes up four
times as much space for the same amount of backlog, which is wasteful).
It is also faster, possibly thanks to bigger chunks being processed in bulk.
Gonna try to figure out if the locking can be improved further.

Also changed to use a syscall for reading KIO buffer from uspace,
to allow better synchronization.
