Port syscons to the alpha. The driver itself has moved to sys/isa as it will

Browse source 
hopefully become a portable driver usable by all architectures.  The api
support files have had to be copied to sys/alpha/include since userland
programs expect to find them in <machine/*.h>.

All the revision history of the i386 syscons has been retained by a
repository copy.
