  -----------
  [libc][rpc] Allocate locks array within process

Replaces the globals currently used. Worth changing to a bitmap
before allowing runtime number of ports >> 64. One bit per port is likely
to be cheap enough that sizing for the worst case is always fine, otherwise
in the future we can change to dynamically allocating it.
