Support forcing all screenshots into a CPU consumer

Looks like a full GPU path is less efficient on some GPU
drivers that we're still using, and CPU is reliably faster...
(there's probably a locking condition going on somewhere, this
needs to be looked into)

    surfaceflinger: odd hw rotation (90/270) patch for swapping width/height

    This patch works in addition to the following commit
    re-implementing ro.sf.hwrotation:
    https://github.com/CyanogenMod/android_frameworks_native/commit/7d283431efffc4402cb1a6cacf5da64729c883bb

    When using values of 90 and 270 for ro.sf.hwrotation the
    LCD width and height also need to be swapped to display properly.

    NOTE: This patch does not fix the initial startup of bootanimation

    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.
