Change the pmap_enter interface to merge access_type and the wired boolean
and arbitrary flags into one argument.
One new flag is PMAP_CANFAIL that tells pmap_enter that it can fail if there
are not enough resources to satisfy the request. If this flag is not passed,
pmap_enter should panic as it should have done before this change (XXX - many
pmaps are still not doing that).
Only i386 and alpha implement CANFAIL for now.
Includes uvm updates from NetBSD.
