Replace all in-tree uses with necessary subset of <sys/{fb,kb,cons}io.h>.
This is also the appropriate fix for exo-tree sources.
Put warnings in <machine/console.h> to discourage use.
November 15th 2000 the warnings will be converted to errors.
January 15th 2001 the <machine/console.h> files will be removed.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Not all mappings are supported, most languages come only with one
encoding since this should be sufficient to get up & running in using
sysinstall, and we are already pretty tight on space. (My previous
commit has already bumped the boot MFS size by another 50 KB for
this.)
This feature requires the `kbdcontrol -L' i've just committed. Plain
text keymaps and the entire scanner are overkill for sysinstall.
Also updated the list of available keymaps while i was at it.
