Add skeleton machine dependent headers and c files for a port of freebsd to a new architecture. This is the base of the sparc64 port, but contains limited machine dependent code, and can be used a base for ports. Included are: - standard machine dependent headers, tweaked for a 64 bit, big endian architecture, including empty versions of all the machine dependent structures - a machine independent atomic.h, which can be used until a port has support for interrupts and the operations really need to be atomic - stub versions of all the machine dependent functions, which panic when called and print out the name of the function that needs to be implemented. functions which are normally in assembly files are not included, but this should reduce the number of different undefined references on the first few compiles from hundreds to 5 or 6 Given minimal startup code and console support it should be trivial to make this compile and run the first few sysinits on almost any architecture.

Now that we have a working OF_printf() since r230631 and a OF_panic() helper since r230632, use these for output and panicing during the early cycles and move cninit() until after the static per-CPU data has been set up. This solves a couple of issue regarding the non- availability of the static per-CPU data: - panic() not working and only making things worse when called, - having to supply a special DELAY() implementation to the low-level console drivers, - curthread accesses of mutex(9) usage in low-level console drivers that aren't conditional due to compiler optimizations (basically, this is the problem described in r227537 but in this case for keyboards attached via uart(4)).
