    dumpstate: Fix calls to su to specify a shell command

    Superuser's su requires that shell commands be specified with the "-c"
    option.  Fix calls to su to explicitly specify this option.

    dumpstate: Skip subsequent showmaps if the first run fails.

    dumpstate takes over six minutes to run as each call to "su" (which
    dumpstate uses opportunistically on states that require root privileges to
    access) takes approximately one second to process.

    The vast majority of these "su" calls are made to "showmap", which is
    called for every running process.  These calls nearly always fail, either
    because dumpstate is denied root access, or because "showmap" isn't
    installed.

    This greatly speeds up the dumpstate process by skipping subsequent
    "showmap" attempts if the first run (on process init) fails.

SurfaceFlinger: Removal of NO_RGBX_8888 flag for OMAP3

Removing this will allow color format of surface to be set for RGBX8888
that can improve performance for 32 bit framebuffer.

Tested on Nook Color with CM10
TI's commit can be found here:
review.omapzoom.org/#/c/21374/3

This will also remove the need to have BOARD_NO_RGBX_8888 := true
in the BoardConfig.mk

sensors: Add dummy light sensor

Some devices have a sysfs toggle for the lightsensor instead of
passing the LUX values for userspace processing; for those,
use BOARD_SYSFS_LIGHT_SENSOR:=<sysfs path>

This is necessary for the rest of userspace to recognize its existence
and toggle it for auto-brightness. It doesn't generate actual light
values, though; all backlight adjustments are made in-kernel.

sensors: dummy ls: set unique handle

handles and types are usually the same, but it's not mandatory.
Sony DASH use custom handles, and the previous assumption broke
Proximity sensor on Sony devices.
