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

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.

Source Split layers always if the driver indicates so by setting
the src_split_always in the capabilities sysfs node.
This is applicable to layers whose width > mixer's width, since
MDP clk rate is dependent on max(mixer_width, layer_width).
This feature can be enabled if the panel height is more than a
certain empirically derived value. Splitting always in those
cases can help with a lower voltage.

For panels that cannot accept commands in both the interfaces, we cannot
send two ROI's (for each half). We merge them into single ROI and split
them across lSplit for MDP mixer use. The ROI's will be merged again
finally before updating the panel in the driver.
- Reads panel property of dual control path.
- If dual control path not supported, merge ROI's before
analysing for composition strategies.

Some of the definitions may not be present on AOSP builds while

- Add utility function for 8x16
- Add internal function to identify if RGB doesn't
support scaling that is read from capabilities node.
- If UI layer needs scaling and RGB pipe doesn't
support scalar, request a VG pipe
- On 8x16, request DMA pipe for WFD

Add support for SourceSplit. The mixers are abstracted from hwc.
There would be no translations to mixer understood destinations.
1) If a layer's crop and position are < 2048, only 1 pipe can be used
irrespective of position.
2) Else 2 pipes can be used with the layer equally split, without
regard to position.

Remove all klockwork warnings and errors for libgralloc,
libhwcomposer, liboverlay, libqdutils, libqservice, libvirtual,
libexternal libraries to avoid buffer overflow and memory leaks.

Some frameworks override malloc() and free() but not getline().
Pre-allocating the buffer avoids heap mismatch on free().

Currently HW revisions are maintained separately between kernel and
user-space. To optimize this there will be single place, exported
msm_mdp.h, where HW revisions will be maintained.

Macro tile is enabled only if all the conditions are met:
1. GPU hardware should support Macro Tiling.
2. MDSS hardware should support Macro Tiling.
3. USAGE flags shouldnt contain GRALLOC_USAGE_SW_READ_OFTEN and
GRALLOC_USAGE_SW_WRITE_OFTEN.
4. RGB 16bit and 32bit formats.
5. persist.hwc.macro_tile_enable flag should be enabled.
PRIV_FLAGS_TILE_RENDERED flag is added to indicate whether the layer
is rendered/composited in Macro Tiling or Linear format.

Add device version inline checks for hardware devices.
Also fixes the issue of 8084 being treated as 8974v2
owing to the expanded range.

1. MDPVersion class can query the capabilities using sysfs node.
Since sysfs node can be read with out opening framebuffer, it is no
longer required.
2. New internal functions updatePanelInfo, updateSplitInfo are added.

During surfaceflinger initialization, the first fb open
call comes from the MDP version check. The MDPVersion
class implements a singleton object, which open and close
the fb device. This initial fb open and close will trigger
the kernel driver to turn on and off the display, which
results two side effects: 1) extra delay in the display on,
2) one flicker when the display is turned on and off.
The change is to close the fd handle in the destructor.

Add support for unevenly split primary displays.
The driver provides info about the split via msm_fb_split sysfs node
For external we assume even split. If driver doesn't specify any split
for primary, we default to even split.

These include constrained targets, with external connected which could
lead to a scarcity of pipes. Furthermore owing to a scarcity of writeback
interfaces, even if pipes are available, we may not be able to still
use rotator.

Parse the panel type from the panel info string using string operations
rather than relying on constant offset (which would have to be update for
any changes in length to the preceding MDP/MDSS version string). Assumes
that panel type is the first character after the first '_' in the panel
info string.

- This adds support for Bandwidth Compression.
- If MDSS supports BWC, then we set BWC flags
to both Rotator(encode) and overlay(decode)

Add support for decimation on top of what MDP can downscale,
because decimation can have quality issues.
B-family MDP downscale of 1/4, plus decimation of 1/16 can let
us have a total downscale of 1/64.
Also decimate by 2 (min) if width is greater than what layer mixer
supports and is not handled by the client.

Userspace can retrieve MDP revision number and number of different
types of MDP pipes (RGB,VG,DMA) information from driver. Add target
