Wifi: Allow configuration of Ad-Hoc (IBSS) networks

Show Ad-Hoc (IBSS) networks in the list of available Wi-Fi networks and allow
to connect to or create new Ad-Hoc (IBSS) networks.

This requires the IBSS changes in frameworks/base and external/wpa_supplicant_8

Wifi: Enable IBSS options only if IBSS is supported

Show IBSS network options only if IBSS mode is supported by the Wifi driver.

This makes use of the new API isIbssSupported() of WifiManager. We have to be
careful to make the query only after we reached WIFI_STATE_ENABLED.

WifiSettingsForSetupWizardXL is left out because it does not handle these
states.

Settings: TRDS 2.0 (3/3)

After testing with huge success we discovered here
and there small problems (like NFC beam animation is broken,
TRDS was disabled on cardock etc) which mainly was caused
due that we used the already from AOSP introduced uiModes
qualifier which could cause in special conditions this
conflicts. Beside that we want a bit more flexibility.
Result: This commit introduces the inverted qualifier as
complete own qualifier undependent of the already AOSP
used ones.

Beside that it fixes all known issues......features:

- it is now completly working over the AOSP Configuration classes
  Means every app get notice of a change trough onConfiguratioChange
  and restarts it's activity if change was detected.
- app can disable that like some other configuration values
  over AndroidMainfest.xml
- beside "inverted" folder another "notinverted" folder is introduced
  for another themeing (eg white)
- qualifier order is direct before the official uiMode qualifiers
  (see AOSP docs)
- All usual Configuration actions can be used with the inverted
  qualifiers....like BroadcastChange, direct read out from every
  app etc. etc. Note: Only system can change the uiInvertedMode

So as you see a real own qualifier now

NOTE: Apktool as well aapt need to be changed to fit the "new
qualifier"....which means that we need to recompile our gapps
that they react as well on this new behaviour. Think we will get them ready
next 2 or 3 days
