Remove a hard-coded table of kernel console I/O functions exported

from sc, vt and sio drivers.  Use instead a linker_set to collect them.

Staticize ??cngetc(), ??cnputc(), etc functions in sc and vt drivers.
We must still have siocngetc() and siocnputc() as globals because they
are directly referred to by i386-gdbstub.c :-(
