When measuring GL latency with dumpsys, it's possible to hit a
race condition if the hardware is fast enough to complete rendering
the test cycle before the latency dump is requested, since it only
matches the latency for live layers (unless it's an animation. See
change I8bded1ea08a4cddefef0aa955401052bb9107c90)
So always save a reference to the last rendered SurfaceView frame,
and dump its values if there isn't an active one.

Android 5.0 cannot form multitouch events from multiple input
devices. So it is not possible to report one touchpoint from the
stylus position and, at the same time, another touchpoint from a
finger touch. Instead, when a new input device starts up the currently
active input is cancelled. This is highly undesirable while writing
with the pen.
The easiest solution is to ignore non-stylus touch events while the
stylus is within range (hovering) of the touchscreen. For example,
N-trig digitizers implement this in hardware. But wacom digitizers do
report pen data simultaneously with touch data. This patch disables
(non-stylus) touch input within 50ms of stylus data. On my Galaxy
Note this is necessary to make stylus input usable.

Looks like a full GPU path is less efficient on some GPU
drivers that we're still using, and CPU is reliably faster...
(there's probably a locking condition going on somewhere, this
needs to be looked into)

This was originally added for b/14445579. An in-development app was
attempting to render to a window as an EGLSurface, then tear that
down, change some window properties, and create a new EGLSurface. The
second eglCreateWindowSurface failed because the window was already
connected. This change went in, but it turned out the real problem was
that the app still (unintentionally) had the surface current. After
the app bug was fixed, nobody revisited whether this change was
actually needed.
Turns out it wasn't needed. After an EGLSurface is both destroyed
*AND* not current (basically refcount==0), we were already
disconnecting the window in ~egl_surface_t().
Apart from being unnecessary and redundant, disconnecting the window
here is wrong for two reasons:
(a) The surface may still be in use after eglDestroySurface, if it was
still current. Rendering is undefined in that case, but disconnecting
the window leads to more catastrophic results than necessary.
(b) It's being called before calling the driver's eglDestroySurface.
The driver will almost definitely have a buffer dequeued that it needs
to cancel, and by disconnecting first we turn that into an error that
they don't have a graceful way to deal with.

This change is porting of following commits related to MDP3
1) SurfaceFlinger: Change to support framebuffer flip for 2D blitters
- Surfaceflinger does not flip framebuffers when there are
no layers marked for HWC_FRAMEBUFFER
- This change checks for the HWC_BLIT flag and will request a flip
to a new FB_TARGET buffer even if there are no FRAMEBUFFER layers
"Change-Id: I1cb44389a05c9ec049d7f0d39c288feccb11a91c"
2) SF: Avoid wormhole clear for BLIT calls
- Do not call GPU clear from SF when composition
type is BLIT as it'll be taken care in HAL.
"Change-Id: Ia613eb9b824c6484ecc8c8fa4ee883545d8541b8"

blocking screen shots.

Avoid disabling DispSync resync if app and SF events aren't

Inside Surface::lock if new buffer is allocated
and DirtyRegion does not cover complete buffer
bounds then copyback may not cover all remaining area
as it copyback only area covered by dirty regions
from other buffers. This will lead to left out
black area which may cause flicker.

sf: Fixes for resolution change in SurfaceFlinger
1. Use active config from HWC when querying display attributes
When we query the display attributes we should use the active
config as reported by HWC in cases where HWC version is 1.4.
In all other cases we should revert to the default config,
config 0, as the active config.
2. Set/update the display config if HWC config change was successful
The new config should only be applied if HWC succeeded in changing
the active config. This would otherwise cause failure or undefined
behavior if the client sets an invalid/unsupported display config.
3. Set the active config at display creation time
When a new display device is added update the active config by
querying HWC.
