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.

-	---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.

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts.  The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames.  With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.
