util.pposix,signal: Pass around various OS numbers as integers [Lua 5.3] Passing around PIDs, UIDs etc as integers makes it more sane in Lua 5.3. Getting 1234.0 as PID is silly. Shouldn't change any behavior as these are all integers on the C side and the integral floats are accepted as integers when passed back from Lua into C.
