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.

+ * Functions to be implemented here are:
+ *
+ * procfs_read_regs(proc, regs)
+ *	Get the current user-visible register set from the process
+ *	and copy it into the regs structure (<machine/reg.h>).
+ *	The process is stopped at the time read_regs is called.
+ *
+ * procfs_write_regs(proc, regs)
+ *	Update the current register set from the passed in regs
+ *	structure.  Take care to avoid clobbering special CPU
+ *	registers or privileged bits in the PSL.
+ *	Depending on the architecture this may have fix-up work to do,
+ *	especially if the IAR or PCW are modified.
+ *	The process is stopped at the time write_regs is called.
+ *
+ * procfs_read_fpregs, procfs_write_fpregs
+ *	deal with the floating point register set, otherwise as above.
+ *
+ * procfs_read_dbregs, procfs_write_dbregs
+ *	deal with the processor debug register set, otherwise as above.
+ *
+ * procfs_sstep(proc)
+ *	Arrange for the process to trap after executing a single instruction.
