bootanimation: allow preload the bootanimation

This patch implements one simple performance enhancement, which
might benefit devices. It is completely opt-in by setting
the following variable.

  * TARGET_BOOTANIMATION_PRELOAD: will preload the bootanimation
    zip to memory; this is handy on devices where the storage
    might be slow. By preloading it, we get quick access to the
    zip file, and the animation doesn't stutter.

bootanimation: allow using RGB565

RGB565 uses considerably less memory, and together with texture
cache, it allows us to offer a really smooth bootanimation on
not so powerful devices.

WiFi : Fix to DHCP to static IP configuration problem

WiFiStateMachine shall update the IP address configuration to
the kernel through NetworkManagementService.This notification
from the kernel is again sent to the connectivity service
through the NetLinkStateTracker and WiFiStateMachine.
Thus ,if the interface is down during this IP address
reconfiguration (for the case of DHCP to Static IP configuration),
Connectivity service shall be notified with old IP address ,NULL(0)
IP address(signifying interface down) and the latest IP address.
This notification was done by updating the IP address using a local
variable , and hence the second notification on the interface down
is over ridden by the last notification , resulting in missed
interface down notification to the connectivity service.This
resulted in failed data connection when IP address is changed from
DHCP to IP on the fly.
Hence ,this gerrit enhances the design and also pass the updated
IP address to the connectivity service.
