libqdutils: Add synchronization to idle invalidator

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.

hwcomposer: Fix a crash with MDP composition.

Reset the current frame data before returning from MDP
composition prepare to avoid accessing previous frame data
in MDP composition draw phase. Avoid the number of app layers
going beyond the layer count limit in MDP composition.

hwcomposer: Reset LayerRotMap if MDP configure fails

For some reason if overlay pipe allocation fails reset the LayerRotMap
to avoid calling rotator sync ioctl which we should not call.

hwcomposer: Add adb property to disable Mixed Mode

This change adds adb property support to disable mixed mode in
MDP Comp. Will be helpful in debugging issues to narrow down the
root cause.

hwcomposer: Fix a deadlock with debug enabled.

If debug property for MDP composition is enabled,
we call dump function from composition thread.
Make sure we are not holding the MDP composition
lock before calling dump function as this also tries
to acquire the same lock and causes a dead lock.

gralloc: Fixes for software composition

Check that the buffer is actually an ion buffer
before calling clean. This is needed for the case
where the physically contiguous framebuffer is mapped.
That framebuffer memory is used for bringup.

gralloc: Do not map framebuffer memory unless needed

The SurfaceFlinger opens the framebuffer module even when it
isn't necessary. It does this for some legacy hals.
Due to this we unnecessarily mmap the fb memory in gralloc.
Do not map this unless the property to use the framebuffer
memory is set.

We do further operations in fb_device_open based on the result of
mapFrameBuffer. However, if mapFrameBuffer is never done, we
could end up with a random crash when using the info values in
fb_device_open. Defaulting to an error value avoids this.

hwc: Minor bug fixes

- Since SF doesnot send blank/unblank event to hwc for
virtual display, handle them as part of primary
- Close acquireFenceFd's of the layers before returning from hwc_set
in case of display commit failure.
- Change in getAspectRatioPosition function to handle portrait and
landscape panels.

hwc: wfd: Call commit even if in pause

We need to call commit on wfd even if in paused state so that pipes
which are unset are actually unstaged from driver

hwc: Fix locking in external connect and composition.

The external configuring flag should be set after holding locks.
Before opening FB for HDMI/WFD, composition should give up any
open external FB resources.

Locks should be held by composition for the entire duration.

gralloc: Add workaround for Jellybean camera drivers

* Arcee is smarter than I am, and discovered that we can simply swap
  two fields to ensure compatibility with Jellybean camera drivers
  having the metadata fields in the private_handle_t struct.
* Enable this by defining QCOM_BSP_CAMERA_ABI_HACK.

hwc: Configure framebuffer before other layers.

If framebuffer needs to be configured, configure it before all the
other layers in mdp composition. This helps in cases where we are
out of SMPs and framebuffer configuration fails owing to that.
Framebuffer being the fallback path, should always get highest
priority when reserving SMP blocks
