PERFORCE change 133376 for review

Change 133376 by imp at imp_lighthouse on 2008/01/16 00:48:25

	Create a mips_proc0_init() (name stole from Juniper code) to
	encapsulate the 8 lines of code that were being cut and paste.
	
	We may be able to have a routine that's from init_param2() through
	the kdb_init too that would save another 8 lines of code from
	all the init functions, but one step at a time.
