This commit enables userland to load and start executing, as it
did before recent vm/ shakeups. fork(2) is still wip.

Changes:
pmap.c:
i) Initial split out of pmap_enter() variants:
 - pmap_enter_locked()
 - pmap_enter_quick()
 - pmap_enter_object()
ii) Improve locking behaviour - make it more consistent with native pmap
iii) Fix two api change related bugs. (kva_alloc() and friends)
iv) Miscellaneous further pmap functions to make boot progress.

pmap_pv.[hc]:
i) Modify the api to export locking behaviour control.
ii) Fine tune pv chunk garbage collecting.
iii) Remove stray debug/instrumentation code.
     "-	if (pmap == kernel_pmap) return true;"
