1. Remove hwc_context_t from libexternal since this is a construct
that should only be used in libhwcomposer.
2. Clean up redundant code by creating utility functions to
a. open a sysfs node in a given mode
b. improving EDID mode storage/manipulation
c. creating/destroying composition objects
3. Add utility functions to
a. get the connected state of the external display
b. determine which interface the external display is connected to
(primary or external)
c. activate the hdmi interface by setting the resolution via an
ioctl
d. update/reset external display information when a device
connected/disconnected

- The primary panels refresh rate can be change by clients
- Required refresh rate will be set by client using metadata
- If there are multiple clients requesting, it will be used only
when the refresh rates are equal, else it resets to default
- Set the new refresh rate only when there are only YUV layers
updating or when the list has only one RGB layer updating
- MdpVersion gets the dyn fps capabilities from panelInfo

1. Add support for Dynamic Resolution Change
We add support for DRC on virtual displays. This is achieved
by reading the width and height attributes that are set as
part of the buffer handle metadata.
For the WFD use cases, the WFD MultiMedia framework will
update the width and height during DRC by using setMetaData
API with UPDATE_BUFFER_GEOMETRY. We then proceed to configure
WB with the new resolution for subsequent frames.
2. Update WB dump with output buffer format and resolution
Update WB dump with output buffer format and resolution. This is
helpful for debugging purposes.

1. Detect and account the number of secure RGB layers present.
2. Mark secure RGB layers for MDP comp in cache based stratergy.
3. If full MDP comp and partial MDP comp fails, Mark secure RGB
layers for MDP composition.
4. In partial MDP comp reject load based composition, if secure
layer is present to avoid GPU composition.
5. Disable idlefallback feature if secure RGB layer is present
to avoid GPU composition.

Remove support for overriding a layer's z to set it up for foreground.
This is unused and can be achieved using pipes staged at required
z-orders.

Clean up scattered definitions of commonly used constants/values.
There is no need in re-defining these in several places.

* A non-updating layer requiring rotation, can make use of
the older rotator buffer written when the layer got first
updated, rather than invoking a new rotator cycle.
* A rotator play is avoided in cases where incoming layer
buffer fd, offset, whf, src-rect, dst-rect, etc are similar
to that of the previous input layer to the rotator.
* For ex: In a usecase where video layer updates happen at
30fps and all other asynchrous UI updates happen at 60fps,
instead of the traditional 60 calls of rotator play per sec,
we now do only 30 thereby saving rotator bandwidth.
* Property "debug.rotcache.disable" can be used to disable
this feature.

Add support for rotator downscale. This is enabled from 8994 onwards
Constraints:
--Downscale should be a power of 2, max upto 32
--Both directions should have equal downscale
--{src_w, src_h} mod downscale = 0
--No BWC
--No Interlaced video support
The rotator's destination rect is modified to reflect the presence of
downscale. Any downscale calcs should be done only after adjusting
crop to meet rotator's requirements.
Smaller downscale is used if we need to chop off any more than 1
line or pixel.

* Limit the number of rotator sessions to 4 both in
LayerRotMap and RotMgr structures
* Make use of MDPVersion getter fuctions to check
for maxMixerWidth and maxDownScale supported by MDP

Read the maximum width mixer can output from drivers
and consider this in identifying if dual pipes are required
to support a layer. So far above 2K dimensions we are using dual
pipes, but 8x39 mixer output can be upto 2560. So there is no
need of dual pipes as long as pipe data is less than this limit.
Compare layer/panel resolutions against this limit to deduce
if there is a need for dual pipes or split.

1. In PTOR feature, offset for the second overlap layer on render
buffer, depends on stride calculated by gralloc for RGBA (4 bpp).
2. If mCopyBit object exists for external, we need setReleaseFd()

* This reverts commit 52b4fdbdbd.
* Since DisplayDevices are not created for non-wfd virtual
displays(CTS/SR/SSD) anymore, we can remove these checks.

Currently for Mdss rotator we manipulate the layer buffer dimensions
to be equal to what rotator's destination dimensions would be, so that
these could be fed to MDP. Instead, this patch introduces APIs in
rotator so that hwc can directly query destination crop, width, height,
format from rotator.
This also simplifies the updateSource() and configRotator() helpers.

- Consider two smallest layers for PTOR feature which uses MDP comp.
- These two layers are rendered on a buffer and are queued to MDP
to acheive full MDP Composition
- This helps to acheive performance enhancement

This change closes the release fence fd in the event that
a failure occurs during the buf sync ioctl. This is additional
sanity to ensure that we are not leaking any fd's in userspace.

1) While setting BWC check for 90 transform and swap crop
2) Calculate decimation in the getDecimationFactor API itself.
Currently, a residual downscale is calculated and the clients have
to take logs and apply forcible decimation like in MdpCtrl
3) Fix bug where transform gets typecasted to bool
