- Use if_printf() and device_printf() in re(4) and remove rl_unit from

Browse Source 
the softc.
- Use callout_init_mtx() and rather than timeout/untimeout in both rl(4)
  and re(4).
- Fix locking for ifmedia by locking the driver in the ifmedia handlers
  rather than in the miibus functions.  (re(4) didn't lock the mii stuff
  at all!)
- Fix some locking in re_ioctl().

Note: the two drivers share the same softc declared in if_rlreg.h, so they
had to be change simultaneously.

MFC after:	 1 week
Tested by:	several on rl(4), none on re(4)
