When there is a state change, open/close only the required channels
instead of blindly closing all the channels. When HDMI is connected,
open the overlay for queueing the frames on the external, and when
hdmi is disconnected, only close the external overlay channel.

With this change application would be specifying 3D format and that would
be handled by hwcomposer would handle it appropriately.

This reverts commit f2dbabe786a12e7e9ae15328550b5ba581c5492e.
This change is not needed any more because we are caching the MDP pipe
contents when closing the channel. So no need to wait for postFB finish.

If there is a SKIP layer present, the SKIP layers are first composited
using the GPU. If there any layer below the SKIP layer that performs
any operations on the FrameBuffer, it results in undesireable results
on the screen e.g. artifacts, since SurfaceFlinger draws the SKIP layers
before the HWComposer.

Refactoring is necessary to attain flexibility in setting mdp overlay params

This change includes new APIs for setting crop rectangle, display params and

respectively.

When performing the setup for bypass operations, check the number
of bypass channels that are in open state. If the count does not
match the number of bypass layers, close all the bypass channels.
This is done to prevent the overlay channels from going into an
inconsistent/undefined state.

If module composition type is MDP or C2D and we have a skipped layer
(usually layers without backing buffers, layers with "invalid"
orientations or debug layers), mark every HWC layer below this layer
for GPU composition.
This logic is needed because ICS SF composes a bunch of z-ordered
HWC_FRAMEBUFFER (GPU) layers first and then the remaining bunch of
z-ordered HWC_OVERLAY layers last which breaks the overall z-ordered
layer rendering requirement. This logic also holds valid for 2-layer
bypass in ICS.

Validate the previous overlay and bypass handles before unlocking
the buffers. The reason for doing this, is that in certain use cases,
after the previous handles are stored, the buffer gets destroyed and the
handle is now invalid. The HWC however doesn't know that the handle is
invalid and tries to unlock the handle, resulting in a failure.

Since composition bypass uses MDP overlays, which
need physically contiguous memory, we cannot use
bypass in cases where the buffers are using ashmem
or other virtual memory. Hence, avoid bypass in
such cases.

- Set the WAIT flag for the primary channel.

For copybit composition, aquire a read lock on the buffer, before
the blit operation and release the lock after the blit operation.
For overlay, aquire a read lock on buffer N that is sent to the
overlay. After the play call for buffer N returns, unlock the lock
held by buffer (N-1).
