Convert rman to use rman_res_t instead of u_long

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

bus_set_resource takes a rid, not a pointer to a rid.

Document my adventures in newbus land. Clarify some examples, especially
that count is in bytes, not bits. There are some drivers that I think make
this mistake. (I've seen counts of 16 in the tree).

Assorted mdoc(7) fixes.

Document what bus_set_resource(9) does. It is used by bus drivers to
bind resources that client drivers later access.
