Message:

Introduce a console lock to prevent line splitting in kernel output

It is a common occurrence to see broken lines on screen or in serial
output due to bad timing. This is an attempt to prevent that without
breaking anything.

It could be considered a stopgap solution, since the whole console
stack deserves a better/faster implementation.
