surfaceflinger: don't handle EVENT_ORIENTATION when !HWC_DEVICE_API_VERSION_1_0

a184463 causes segfault on boot for the enrc2b (and probably others), this fixes it.

surfaceflinger: Consolidate display orientation compensation hooks

Dedupe rotation calculation code and make rotation a statically
available property in the DisplayDevice

SF: Avoid wormhole clear for BLIT calls

Do not call GPU clear from SF when composition
type is BLIT as it'll be taken care in HAL.

sf: Fix detection of 0.3 hwcomposer

The format was different, so look at the header bits too...

sf: Don't do premultiplied alpha blending on the statusbar for hwc <= 0.3

Blending the translucent statusbar with the limited alpha implementation
of older HWC versions is glitch-prone, so don't do that with the compositor
at all

sensorservice: Fix init sequence for pre-1.1 API sensor HALs

The sensors API introduced a new flush() method that older binaries
won't have. For those, replace the firstFlush invocation with a
setDelay call since a lot of implementations interpreted that as
the initialization step.
We also don't want any kind of call to flush() to happen when it
isn't there, since it'll either hit a random OEM extension or
a memory address we really don't want to execute.

sensorservice: Set the rate for pre-1.1 HALs _after_ activation

We want to be sure these are applied in the same sequence they
used to be...
