- Convert msleep(9) in select(2) and poll(2) to cv_*wait*(9).

- Since polling should not involve sleeping, keep holding a
  process lock upon scanning file descriptors.

- Hold a reference to every file descriptor prior to entering
  polling loop in order to avoid lock order reversal between
  lockmgr and p_mtx upon calling fdrop() in fo_poll().
  (NOTE: this work has not been done for netncp and netsmb
  yet because a socket itself has no reference counts.)
