This commit has the following changes:
1. Use hdmi switch node for hdmi hotplug
- uses /devices/virtual/switch/hdmi switch_state to determine
the hdmi connect/disconnect
- this switch will be set to 1 on connect and 0 on disconnect
- on connect, open framebuffer device, will trigger the hdcp
authentication.
- the driver will set the hdmi_audio switch to indicate that
the HDMI sink supports audio
2. Enable HDP on unblank
- this will resolve the device freeze during the bootup with hdmi
connected

(cherry picked from commit 953b04b3cbba2f91d25795e5b0560c13d47844b0)
Cleanup overlay for external from the draw thread. If done from the uevent
thread, its possible that the object being used by draw thread is deleted by
uevent thread.
This also removes unnecessary side-effects where libexternal sets states in
hwc, whereas, it could be set from hwc itself. There should be no need for
libexternal to modify states in hwc.

Wait for hwc_set completion if already in progress before processing
the async events.

We are seeing errors where a device's hwcVsyncThread is not present for some
reason. The surface flinger has not crashed, so either the thread never got
created, or it exited withouth throwing an error. This patch adds some more
verbose on-error logging to the HWC as an attempt to verify the theory that the
thread does not get created, or fails in pthread_create. While we're at it, we
add the same logging at pthread_create() for hwcUeventThread, as well.
Also, replace the lseek()+read() with a pread() combo in the vsync thread.

* Read sysfs entries to get vsync timestamp from kernel.
* External display continues to use uevents for hotplug events
* A new thread, vsyncThread is created to read and send vsync
timestamps to HAL.
* Disable H/W VSYNC for MDP 5.x targets until kernel changes are
complete.
* Synchronization is needed to make sure read() is not called
by hwcVsyncThread when VSYNC is disabled.

Add QService binder interface to enable communication
to display by the mediaserver for Securing/Unsecuring start and end
notifications.
Create separate lib for external.
Clear reserved field before applying format.

Also store the hwc_procs_t* into a dedicated field instead of one of
the hwc_composer_device_1_t::reserved_procs slots, which are supposed
to be NULL so the structure can be extended without breaking backwards
binary compatibility.

the hdmi driver can send change uevent anytime, in which case, the
connected state was getting set to 0, due to its default value.
