code for ints than for bytes.

After my bit scan re-writing the SIOCSIWSCAN wext ioctl no longer supported
scanning for a specific SSID. However, wpa_supplicant is a possible user of
this ioctl, so here is code that add's this.

While passing, removed even more of the debugfs-based scanning. You can (and
should) the SIOCSIWSCAN to ask for scans, so there is no need for
proprietary interfaces for scanning. And, besides, the scan result couldn't
be used further, e.g. not for associating.

This changes the code that is used for scanning and makes it hopefully
easier to understand:

* move function into logical blocks
* create a bunch of lbs_scan_add_XXXX_tlv() functions, that
  help to create the TLV parameter of CMD_802_11_SCAN
* all of them are now called from the much simpler lbs_do_scan()
* no **puserscancfg double-pointers :-)

The transmit and receive traffic as soon as the mesh interface is
brought up.

Test case 1:  Bring up only the mesh interface and ping.  No need for
any iwconfig commands on the main interface.

$ ifconfig msh0 192.168.5.3
$ iwconfig msh0 channel X
$ ping 192.168.5.2
If ping succeeds, PASS

Test case 2:  Associate with the main interface, and turn off AP.  Mesh
interface should not lose connectivity.

$ iwconfig eth0 mode managed essid "my_ssid"
$ ifconfig msh0 192.168.5.3
$ ping 192.168.5.2
<turn off access point>
If ping continues uninterrupted, PASS

Currently, when you define LBS_DEB_HEX, you get every hex dump in the
whole driver, e.g. for LBS_DEB_CMD, LBS_DEB_RX, LBS_DEB_TX etc. This
patch makes sure that you only get the hexdump that you're interested in.

Renamed lbs_dbg_hex() into lbs_deb_hex(), like the other lbs_deb_XXX()
macros.

Made lbs_deb_hex() issue a line feed (and a new prompt) after 16 bytes.

As lbs_deb_hex() now prints the ":" after the prompt by itself, removed
the misc colons in the various *.c files.

lbs_deb_XXX() now print the debug category as well.

As lbs_deb_XXX() --- and especially lbs_deb_11d() --- now print the
category, I removed various "11D:" prefixes in 11d.c as well.

Remove unused/duplicated fields and consolidate static data rate arrays,
for example the libertas_supported_rates[] and datarates[] arrays in
the bss_descriptor structure, and the libertas_supported_rates field
in the wlan_adapter structure.

Introduce libertas_fw_index_to_data_rate and libertas_data_rate_to_fw_index
functions and use them everywhere firmware requires a rate index rather
than a rate array.

The firmware requires the 4 basic rates to have the MSB set, but most
other stuff doesn't, like WEXT and mesh ioctls.  Therefore, only set the MSB
on basic rates when pushing rate arrays to firmware instead of doing a ton
of (rate & 0x7f) everywhere.

With this patch, scanning with mshX interface will only return mesh networks. To
differentiate them, a specific mesh IE in beacons/probe responses is used. This
IE has been introduced in firmware release 5.110.14. Note:

Even though there can be at most a single mesh per channel, this scan might
return several networks in the same channel.

If all nodes in a mesh network are associated to an AP, they won't produce
beacons/probe responses, thus the network will not be listed. This will be fixed
in future firmware releases.

Scan on ethX interface is not filtered, so it will list both mesh and non-mesh
networks.
