SF: Fix invalid reduction of transparent region from a layer.

Reduce transparent region from a layer only if the transparent
region has valid intersection with the layer. Otherwise, reducing
a transparent region lying completely outside of the layer leads to
invalid sourcecrop values for the layer.

sf: Determine if virtual display can use HWC for composition

For HWC virtual display using V4L2 approach:
1. HWC virtual display implementation doesn't send output buffer
   back to Surface Flinger.
2. For non-wfd virtual displays(e.g. Simulated Secondary Displays,
   Screen Record, CTS etc..), configure VDS to use GPU for
   composition on output/sink buffer.
3. For wfd virtual display (a.k.a hybrid wfd), use
   Framebuffer surface (similar to external display mechanism).

For HWC virtual display using VDS approach:
1. HWC is allocated for first virtual display connection.
2. Subsequent virtual display sessions will be composed by GLES driver.
ToDo: Modify VDS component to allocate hwcDisplayId based on
mForceHwcCopy (which is based on Usage Flags)

Extend installd to support SELinux restorecon function.

Implement new restorecondata function which will allow
the relabeling of /data/data and /data/user directories.
This is needed in the case of certain OTAs. Not every
boot will apply this relabeling however. Consult change
I77bf2a0c4c34b1feef6fdf4d6c3bd92dbf32f4a1 for
clarification on this issue.

Proper security labeling of multi-user data directories.

Add seinfo paramater to appropriate make directory
functions. This allows proper labeling for multi-user
scenarios.

Convert all selinux_android_restorecon and _setfilecon calls to new API.

libselinux selinux_android_restorecon API is changing to the more
general interface with flags and dropping the older variants.

Also get rid of the old, no longer used selinux_android_setfilecon API
and rename selinux_android_setfilecon2 to it as it is the only API in use.

MemoryHeapBase: ifdef for gingerbread/froyo compatibility

Allow to "revert" by a board config flag the offset member addon
see commit f24c4cd0f20 (aosp change id Ie618fb5c0718e)

This change is required to use overlay based proprietary camera libs
coming from gingerbread and froyo builds.

This change also requires a global cflag named BINDER_COMPAT
because a lot of modules use the MemoryHeap includes

Add this in your BoardConfig.mk :
COMMON_GLOBAL_CFLAGS += -DBINDER_COMPAT

Backported from /#/c/13317/

sensorservice: Add legacy sensors fusion.

This change allows devices with accelerometer & magnetometer but
without gyroscope to still get virtual sensors such as Gravity,
Linear Acceleration and Rotation Vector.
