carl9170 firmware: initial WoWLAN support

Unlike the previous proof-of-concept implementation, this
one supports nl80211's magic packet & disconnect wakeup
triggers. Furthermore, the trigger can be enabled from
userspace with "iw", so there's no need for a custom
firmware anymore.

Quote from Marius L. Meyer:
I discovered what the problem was. The directory include/generated does not
exist and does not get created anywhere in the process. So when
configure/conf tries to rename .tmpconfig.h to include/generated/autoconf.h,
it fails. The problem is solved by simply creating the directory before
running autogen.sh.

carl9170 firmware: Wake-on-LAN support

With this feature enabled, the device will stay

[Suspend to RAM!].

Furthermore, it scans all incoming 802.11 data frames
for a MAGIC WOL pattern and - when found - propagates
the wake-up call to the USB Host.

Notes/Limitations:
* Your host has to support USB remote wake-up.
  [In some cases, /proc/acpi/wakeup has to be
   configured as well - see Google for more
   details]

* The MAC address is taken from the device EEPROM.
  [so, ifconfig dev hw ether overrides don't
   work (yet)]

* The magic pattern has to be within the first
  320 bytes of the data frame.

* The magic frames has to be send unencrypted.
  Therefore the WOL initiator has to support
  frame injection [not a problem for most
  mac80211-based drivers].

* The initatior need to be in range and on the
  same channel as well.

mac80211: Update mesh constants to approved IEEE ANA values

This patch updates IEEE802.11 mesh constants to be consistent with newly
approved values. It modifies some values, as well as adds many new constants
in preparation for updating mesh code to the current 802.11s drafts. ANA
numbers were taken from:
https://mentor.ieee.org/802.11/dcn/09/11-09-0031-12-0000-ana-database-assigned-number-authority.xls

A few notes are in order:
1. This will break backwards compatibility with existing Linux kernels as
over-the-air constants have changed.
2. Some old and obsolete constants have been retained for now as the mesh code
itself hasn't been updated yet to the new 802.11s draft. This was desired to
keep the existing mesh scheme working until it can be updated. Adding the
approved values is the first step in updating the mesh code.
3. Obsolete constants have been clearly marked.
4. All ANA approved 802.11s constants have been added.
