Seperate out rectangle deduction from the layer cropping. Update

This makes the function generic enough to be used by other

display: Clean up binder interface

The current binder implementation is inflexible when it comes to
adding new input/output parameters. It also needs a lot of
boilerplate code written when adding a simple enable/disable type
command.

Instead, let clients specify the parcels they want to pass and
unparcel them at the end points only.
Please note that it is assumed that all commands coming in
need the same permission checks. If this is no longer the case,
some commands need to be split out on the receiver end in
IQService.cpp.
This change also simplifies the code end clients need to write.
They should be able to include QServiceUtils and call a single
function to set the binder up and make the call.

qdutils: Add display config to qdutils

This API is meant for system level users that need to get/set
various display attributes that are normally not available via
the regular Android framework channels.
Initially the APIs exposed are to check HDMI status, get display
attributes and set HSIC data.
Only physically connected displays are supported for now.

hwc: Reset layer-to-rotator map and fences on configuration failure

When a rotator or mdp configuration for a display fails, reset the
layer-to-rotator mappings for that display and reset the release
fences for the rotator objects used for that display.

Note: The rotator itself is offline and not tied to any mixer. It is
from the mappings that we deduce which rotator object was used for
layers of which display. Also we don't delete rotator objects held
for a specific display, since during stability runs, failures could
repeat each round and we end up allocating and deallocating memory
unnecessarily. The rotator objects will be deleted automatically
when not required anymore.

hwc: mdpcomp: Make all pipes available if a frame fails

Make all pipes in overlay available, if programming a frame (list)
fails. The failure could be due to commit failure, in which case the
overlay itself will make pipes available.

The failure can also be owing to lack of pipes, since we don't allow
switching pipes across mixers any more. This is particularly a problem
for split-panels. This fix addresses this latter case.

hwc: Update rotator object handling in error cases

Earlier, on configuration errors, we simply drained the fences held
by current rotator objects and went to GPU comp. The rotator objects
were deleted in the subsequent rounds, if they remained unused.

If we don't use GPU comp on failure but use other strategies, then we
need to mark the rotator objects for a display for reuse, so that
other strategies can use them.

Also any failure resets on overlay or rotator need to happen from
functions that call configuration helpers rather than the  helper
themselves. Leaving cleanup to black-box helpers is not desirable.

Revert "libhwcomposer: print a log if there is any delay in vsync read."

This reverts commit 624cef4052af2995c6360bca71f6acbf529cbe3a.
This log is misleading as it does not print the actual vsync time
when vsync is disabled then enabled. It prints accumulated time
from vsync disable to next vsync enable.
