Kernel support for new PCVT console mouse features.

- Basic cut/paste functionality.
- Wheel mouse support (wheel rolls page-by-page through scrollback buffer).
- Copybuffer ownership. i.e., if User X logs in the console and selects text,
  when User Y logs in later the buffer cannot be pasted.

Big thanks to Jean-Baptiste Marchand, Julien Montagne, and Jerome Verdon for
implementing this.
