Disable touch while using the stylus (Galaxy Note)

Android 4.0 cannot form multitouch events from multiple input
devices. So it is not possible to report one touchpoint from the
stylus position and, at the same time, another touchpoint from a
finger touch. Instead, when a new input device starts up the currently
active input is cancelled. This is highly undesirable while writing
with the pen.

The easiest solution is to ignore non-stylus touch events while the
stylus is within range (hovering) of the touchscreen. For example,
N-trig digitizers implement this in hardware. But wacom digitizers do
report pen data simultaneously with touch data. This patch disables
(non-stylus) touch input within 50ms of stylus data. On my Galaxy
Note this is necessary to make stylus input usable.

Allow mounting of multiple volumes via mass storage (framework part)

Cherry-pick from CM9.

The volumes to mount is taken from storage_list.xml (allowMassStorage)
rather than ro.additionalmounts in CM7.

    MountService: Remount all volumes after USB disconnect

    If USB was removed while UMS was enabled, the MountService was only
    remounting the primary share.  Any other shares, like the HTC Inc's
    emmc, were left in limbo.  This patch now iterates over *all* shared
    volumes to remount after disconnect.

    MountService: Only notify PackageManager for true ASEC changes

    MountService can be dealing with multiple mounts (emmc, sdcard), but
    only the EXTERNAL_STORAGE has any ASEC mounts on it.  Since the PMS
    updateExternalMediaStatus doesn't specify the path, we need to make sure
    it's only called for the real ASEC mount.  Otherwise we get into nasty
    race conditions when multiple mounts are coming and going, like during
    UMS transitions, and sdcard-installed apps tend to break.

    MountService: Unmount secondary volumes more carefully

    Use the same message handler for unmounting both the ASEC external-
    storage path and any secondary paths like emmc.  This seems to help with

    Allow multiple shareable SD Cards by using getShareableVolumes()
    to get all the volumes that are shareable and allowing
    sharing/unsharing for all of them rather than just the hardcoded
    getExternalStorage calls.

    Unmount immediately if PM is not updating and not an ASEC
    mount. Change from Josh Stone.

Fix don't interrupt ongoing PIN/PUK verification

This fixes an issue which only occurs if
1. you use a SIM PIN
2. the PIN verification takes longer than the screen timeout is. e.g. when then screen turns black while "unlocking SIM" message is displayed!

It might be possible to simulate the bug by pressing power quickly after the PIN has ben entered and "unlocking SIM" message is still being displayed.

If the PIN verification takes longer thant the screen timeout is then the screen turns black.
If that happens LockPatternKeyguardView.reset() is called which then forces a re-creation of the view. But then the original created
SimUnlockScreen.onSimLockChangedResponse callback never receives the success message for the SIM unlock.
What then happens is that the LockPatternKeyguardView is re-created again and again whenever screen turns off while waiting
until we receive a SIM state changed event e.g. until we are back on network.
But when that happens we are presented the pattern unlock screen. With a single touch we can then (finally) get on the homescreen.

The fix removes the forced re-creation of the LockPatternKeyguardView if there is a PIN/PUK verification in progress. Which leads to a 'normal' unlock behavior:
1. enter pin
2. "unlocking SIM" message is displayed
3. maybe screen turns off after timeout
4. after some seconds you get on the homescreen directly

fix NAT detection in SipService

The NAT detection in SipService just checks if the client IP is a
private address. In this case keep alive is enforced. But if you
use a server which also has a private address, keep alive should not
be enabled to save battery.
This patch modifies the NAT detection to also check the server IP.
If both are private, NAT is not detected.

Improve scrolling cache

Scrolling cache helps make short scrolls/flings smooth but will
cause stutter when long flings are made. This patch disables
scrolling cache when long flings are made.

This patch also fixes a related bug where scrolling cache will
not be enabled properly when transitioning from flinging to scrolling.
