Kernel support for console mouse functionality which will be controlled by

the wsmoused daemon (replacement for moused which was used with PCVT). Adds
a "getchar" method to the display drivers which returns the value of the
character currently under the cursor (e.g., so it may be inversed). From jbm@.

Still needs a bit of cleanup and improvement, especially X cohabitation
features. The pointer moves to fast as well. These sorts of issues will be
corrected in-tree.
