frameworks/base: Add an option to disable hw acceleration via system prop.

Hardware accelerated graphics on devices without updated proprietary files
and/or drivers is causing graphics glitches and reboots. Add the ability
to disable it to alleviate the problems until each device can support it.

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

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
    additional race conditions encountered on Inc.

    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.

Make "SD Card removed" notification dismissible if the removed SD Card is not the primary storage

The Galaxy S uses the "external SD Card" as the extended storage
and it the notification should be dismissible as it's okay not
to have it.

Additionally, this patch also not hide the USB storage mount dialog
if the removed storage is not the primary storage
