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.

Wifi: Add frequency selection for new IBSS

Settings: rotation settings for devices with hardware rotation lock

All settings would be disabled on devices with hardware rotation
lock due to dependency setting. Disable dependency to allow setting
swap volume and rotation degrees on those devices.

DataUsageSummary: fix mobile data usage display for sim-less devices

- Don't assume the device has a sim card. Check for a phone number
  instead. Otherwise the mobile data usage screen will not show up
  on sim-less CDMA devices.

DataUsageSummary: fix mobile data usage display for GSM devices with no number

Some providers don't write phone number onto SIM card causing the
phone number check introduced in the partially reverted commit to fail.
Re-introduce the original check with the "or" condition.

This partially reverts commit 4c51b45355b9d6fed973f946738bf455a8b7c9ea.

Check if the Activity is finishing before showDialog()

Check if the Activity is going through its finishing phase before
displaying the Dialog, because Showing dialog once the activity
is no longer in context will cause BadTokenException.

WLAN configuration (static address): reject IPv6 addresses.

Without this, entering an IPv6 address as the interface address (or possibly
also others, such as gateway address) will, on connection to that WLAN,
trigger an uncaught exception:

*** FATAL EXCEPTION IN SYSTEM PROCESS: WifiStateMachine
java.lang.IllegalArgumentException: command '59 interface setcfg wlan0 2001:db8::ffff 24 up' failed with '501 59 Flag unsupported'
	at com.android.server.NetworkManagementService.setInterfaceConfig(NetworkManagementService.java:546)

	at com.android.internal.util.StateMachine$SmHandler.invokeEnterMethods(StateMachine.java:958)
[etc.]

followed by a restart of the UI then another connection attempt. So long as
the misconfigured-for AP is present (and preferred?), this will continue to
happen.

No back icon in action bar of APN Settings

When entering the APN menu, the actionbar is missing a back
