DECstation MIPS3 support: wbflush() is cpu-dependent, need declaration from machine/locore.h. From Toru Nishimura: _FORKBRAINDAMAGE is gone, user process entered through proc_trampoline() [also cpu-dependent].

Define the conventional pmax locore entry-point names to be calls through an vector (struct) of function pointers. Add prototype declarations for each vector entry. Add declarations for the r2000 (MIPS-I) and r4000 (MIPS-III) locore versions of the relevant functions.
