Single idle time value is not working well on all targets as
power saving is dependent on specific GPU behavior on the device.
We need to come up with per target default idle time based on power
profiling. Retain the property to set default idle time per target.

Add support for dynamically setting idle timeout values.
Move default idle timeout setting to IdleInvalidator.
Fix static var naming, handle errors from IdleInvalidator in hwc.
Property debug.hwc.idletime is removed with this change.
Example:
1) Set idle timeout to 100ms
adb shell service call display.qservice 16 i32 100
16 is the code for SET_IDLE_TIMEOUT, 100 is time in ms
2) Disable idle timeout
adb shell service call display.qservice 16 i32 0

1. Use kernel timer interrupt to signal about the timeout to
Invalidator thread and fallback to GPU composition.
2. This implementation avoids waking up the Invalidator thread for
every idletimeout value during continuous update.

Currently the idle timeout is in a range from idle_timeout / 2
to idle_timeout, since we didn't need precise values.
Change this to a fixed value using timestamps, because the timeout
is too low and warrants precision.

Protect invalidator data from accessing multiple threads
asynchronously. Composition thread and idle invalidator
threads could access at same time. Add locking to protect
invalidator class member variables.

This change
1) implements MDP Composition upto 3 layers
2) adds invalidator support to fall back to FB
composition during idle screen condition.

* Rename qcomui directory to qdutils
* Avoid inclusion of qcom_ui header
* Add class to get MDP version
* Add namespace for qdutils to prevent collison
