H A Dif_rl.cdiff 131606 Mon Jul 05 00:51:32 MDT 2004 bms Locking cleanup for rl(4).
- Eliminate the use of a recursive mutex.
- Mark the driver INTR_MPSAFE.

This work is incomplete and will be refined in a future commit.
- Most notably, _locked() variants of entry points need to be introduced.
- The mii upcall/downcall may still be racy.
- Add a stubbed-out guard against racing rl_detach() for the time being.
