028508cad5 hopefully fixe a race condition in sf initialization
if we received a vsync event during SF init, we could crash
as not all objects were ready to go.

8630320433 split HWComposer out of DisplayHardware
we will only ever have a single instance of HWComposer, so
it's now an attribute of SurfaceFlinger, instead of being part
of DisplayHardware.

DisplayHardware now just represents a "display" (it should be renamed).

this attribute can be set through a regular transaction using
SurfaceComposerClient (just like any other attribute, eg: position or size)

8b33f03232 update SF binder protocol to support setting display attributes
no change of functionality -- the old behavior is implemented
on top of this new protocol.
this new protocol will allow, eventually, to pass informations
about displays and layer stacks.

10fbdb6059 surfaceflinger: call into hardware composer to blank screen
Call into the new HWC blank operation to blank or unblank the screen.
Legacy systems may have already blanked the screen via early suspend,
and can choose to not implement the blank operation in their hardware
composer implementation.

3094df359d First prototype atttempting to support an external display
both API and implementation will change, this is just a prototype
intended to show feasability.

SurfaceFlinger is passed an ISurfaceTexture through a new
callback, it is in turn used to create an EGLSurface which
surfaceflinger will draw into in addition to the main screen.

dc5b63e40e small improvement to sensor fusion
1) there was a typo when computing the system covariance
a term in dT^3 was ommitted; the impact was was very limited
because of how small this term is.

2) initialize the system covariance matrix with non-zero
values for the gyro-bias part. this improves the initial
bias estimation speed significantly.

3) added comments here and there

1a62301fc5 handle EINTR when calling sensor HAL's poll function
some sensor HALs don't handle EINTR, make sure to catch it in the
sensorservice.

also if we ever encounter an error that we can't handle, we abort
which will restart us (or the whole system process if we're running
in it)

62569ecf52 SensorService now always clamps the requested rate
Requested rate will be clamped to the minimum rate and then
to 1ms. Previously we would return an error if a lower
rate was asked. The SensorManager documentation wording
allows this change.

We do this to get more consistancy between all the sensor
drivers / HALs

ae09d65f5b fix an issue where SensorService could request an invalid sensor delay
When the app requests "fastest", the java layer encodes this as a
delay of 0. SensorService was passing this unchanged to the HAL.
However the HAL is required to reject delays lower that the
advertised lower delay.

1cb13461a8 PermissionCache caches permission checks
This is intended to absorb the cost of the IPC
to the permission controller.
Cached permission checks cost about 3us, while
full blown ones are two orders of magnitude slower.

CAVEAT: PermissionCache can only handle system
permissions safely for now, because the cache is
not purged upon global permission changes.
