Log Message:
Rather than pmap_boostrap2() returning the address of the lwp0 uarea,
let pmap_bootstrap2() construct the fake exception frame, initialize
lwp0.l_md.md_regs, and return the new lwp0 stack pointer, thus removing
a bunch of duplicated asm code in each platform's locore.s.

XXX amiga and atari TBD, but the changes will be less mechanical.

XXX sun2/sun3/sun3x TBD, require a slightly different set of mechanical
changes.
