net/ieee80211 -> drivers/net/ipw2x00/libipw_* rename

The old ieee80211 code only remains as a support library for the ipw2100
and ipw2200 drivers.  So, move the code and rename it appropriately to
reflects it's true purpose and status.

-	bool "Full debugging output for the old IEEE80211 stack"
-	depends on IEEE80211
-	---help---
-	  This option will enable debug tracing output for the
-	  ieee80211 network stack.
-
-	  This will result in the kernel module being ~70k larger.  You
-	  can control which debug output is sent to the kernel log by
-	  setting the value in
-
-	  /proc/net/ieee80211/debug_level
-
-	  For example:
-
-	  % echo 0x00000FFO > /proc/net/ieee80211/debug_level
-
-	  For a list of values you can assign to debug_level, you
-	  can look at the bit mask values in <net/ieee80211.h>
-
-	  If you are not trying to debug or develop the ieee80211
-	  subsystem, you most likely want to say N here.
