UVM typedef struct

[Mindaugas Rasiukevicius <rmind%netbsd.org@localhost>]

Hello,

I would like to typedef and replace the struct usage in UVM, so that
struct vm_map would become vm_map_t, struct vm_anon - vm_anon_t, and so
on. It increases readability and makes UVM consistent in this respect
with other subsystems (cf. sys/kern). Any concerns?

I would like to do this in one go, since <chs> has mentioned that "slow"
diverge would prolong his pain. :)
