        src/sys/dev/ic: rtw.c rtwreg.h rtwvar.h

Log Message:
Miscellaneous Realtek RTL8180L driver improvements:

1 Added new sysctl controls for debugging.

2 Improve detection & support for hardware WEP.

3 Revamp handling of transmit descriptor rings.

4 Reliably IFF_OACTIVE when transmit descriptors are available, to
  stop the transmit section of the driver from freezing up.

5 Fix beacon transmission in adhoc and hostap modes.  XXX There is
  a wart in hostap mode, where beacons are transmitted at 1/2 the
  correct rate.  Load beacon descriptors when the RTW_INTR_BINT
  interrupt arrives; schedule RTW_INTR_BINT 1ms ahead of the target
  beacon time.

6 Recover more gracefully from tx/rx errors: avoid
  transmitter/receiver/chip resets.  Try to re-synchronize software
  state with hardware state---e.g., load next descriptor pointer
  from hardware.

7 Activate the transmit watchdog timer for beacons as well as other
  packets.

8 Introduce rtw_idle() that waits for transmit DMA to finish; call
  it before resetting the transmitter.
